herd consisted of forty-eight head, exclusive of calves, the latter being in all our calculations excluded. One animal after an other was attacked till the 12th of April, when thirteen head had died, and most of those remaining we re showing symptoms of disease. They were afterwards killed by order of the Commissioners, and a few examined with the following results:

Autopsy 1.-This cow appeared badly. She coughed, but it was said, ate well. The posterior lobe of the lung adhered to the diaphragm, was indurated, and contained a cyst in which was a very small quantity of pus, and a mass of detached lung of the size of a quart measure. This was connected with the main portion of the lung by bronchi, some of which had been cut off in such a manner as to admit air into the cyst. The mass was offensive, friable, and on incision did not present the bright, mottled, organized appearance of similar masses lying in air-tight cysts. There was no serum in the chest.-Dr. MARTIN, April 12, 1860.

Autopsy 2.-An ox 7 years old. The lung was extensively and firmly adherent in various parts, and almost "as hard as a stone." On incision there was found a large cyst containing pus and lymph. - Drs. DADD and THAYER, April 19, 1860.

Autopsy 3.-A steer 3 years old. The owner said that this animal was but slightly, if at all sick. The left lung was adherent to the pleura costalis, and diaphragm. On incision there was found in the middle a large cyst containing pulmonary tissue. The right lung was adherent, but its substance healthy.-Drs. DADD and THAYER, April 19, 1860.

Autopsy 4.-A steer 2 years old. Marked adhesion of the posterior superior portion of the lung to the diaphragm. Some consolidation of the lung. The right lung contained a cyst in which was a mass not entirely separated.-Drs. DADD and THAYER, April 19, 1860.

Autopsy 5.-A cow 8 years old. The owner said that this animal was one of the most healthy in his herd. At the apex of the left lung was a very large slough. There was also red hepatization.-Drs. Dadd and THAYER, April 19, 1860.

Autopsy 6.-An ox 7 years old, owned by Curtis Stoddard, and exposed to the Chenery calf during the illness of the latter. The superior anterior portion of the right lung was much enlarged, and contained a large cyst, in which was a quantity of pus and a mass of detached pulmonary tissue. Left lung adherent to the diaphragm.— Drs. DADD and TYLER, April 20, 1860.

Autopsy 7.-The anterior lobe of the right lung adhered to the sternum. A portion of the pulmonary tissue was separated and contained in a cyst. Drs. BATES, DADD and THAYER, April 21, 1860.

Autopsy 8.-A yearling heifer.

Much serum was found in the chest,

and the pleural surfaces were extensively adherent. The substance of the right lung was completely marbled, some parts, having suppurated while others were only indurated.-Dr. TYLER, April 27, 1860.

Other examinations are reported in connection with the herd, but in such language that no definite conclusion can be drawn from them.

Alden Olmstead's Herd.

Monday, November 28, 1859, Leonard Stoddard sold a pair of oxen from his diseased herd to Alden Olmstead, of the same town. Mr. Olmstead kept the oxen till the next Saturday, and then exchanged them for another yoke belonging to William F. Doane, who kept them until they were killed on May 9th, 1860. This yoke of oxen showed at their examination after death unequivocal marks of disease of a character similar to that previously described.

In two weeks after these oxen left Mr. Olmstead's herd, one of his (Olmstead's) animals, was attacked with coughing, shivering, grunting, and rapid respiration. In two or three weeks it died, but there was no post mortem examination. One animal after another was taken sick, so that on the 12th of April seven out of twenty-three had died, or were so near death, that, to prevent hopeless suffering, they were slaughtered. Many of the remaining animals were in a bad condition, and the entire herd was finally slaughtered by the Commissioners. Several examinations were made.

Autopsy 9.-Killed a cow which had been sick nineteen days. She was feeble, had but little appetite, diarrhoea, cough, and shortness of breath. Hair rough, &c. Percussion dull over all the left side of chest, with absence of respiration. The left pleural cavity contained several gallons of serum, by estimate. Over the costal pleura was a firm layer of lymph resembling the velvety parts of tripe. The whole lung was indurated, especially at its base, and brittle, like liver. No pus. Right side and lung healthy.-Dr. MARTIN, April 11, 1860.

Autopsy 10.-Killed a cow 10 years old. Sick since January. Dulness over the left side. On opening it there was a gush of fœtid matter as thick as tar. Strong adhesions to the ribs. In this lung was a large tumor enveloped in a cyst or sac. Right lung indurated.-Drs. DADD, THAYER and TYLER, April 19, 1860.

Autopsy 11. Killed a calf 3 weeks old. In the right pleural cavity was a quart of serum. Lymph, easily separated, was spread over the surface of the lung. The left lung adhered to the ribs, sternum, and pericardium.-Drs. DADD, THAYER and TYLER, April 19, 1860.

Autopsy 12.-Killed a cow 10 years old, which had been sick three or four months. The posterior superior portions of the right lung adhered so strongly to the ribs and diaphragm, that the knife was necessary for their separation. On opening the posterior part of the lung a detached mass was found, very soft, surrounded by pus and contained in a sac. Left lung healthy.-Drs. BATES, DADD and THAYER, April 21, 1860.

Autopsy 13.-Left lung healthy, but slight adhesions to diaphragm. Right lung firmly adherent to the diaphragm. In it was found a mass of consolidated lung not entirely separated.-Drs. BATES, DADD and THAYER, April 21, 1860.

Autopsy 14.-Killed a calf 4 weeks old. Right lung inflamed. Left chest filled with serum. Lung covered with lymph.-Drs. Bates, DADD and THAYER, April 21, 1860.

Autopsy 15.-Killed a cow 9 years old, and mother of the calf. In the right lung was a cyst of the size of a pullet's egg, filled with pus The left lung contained a small cyst filled with the same. Heart flabby -Drs. BATES, DADD and THAYER, April 21, 1860.

Autopsy 16.-Killed a stag that was in the "big team." Three months before, he had been sick for four weeks, but had recovered, and had been working very hard. Serum in the right pleural cavity. Lung indurated, and adherent throughout so strongly to the ribs and diaphragm, that it was necessary to cut or scrape it off. In this lung was a small cyst. Examined May 9, 1860.

Autopsy 17.-Killed the other stag. Left lung useless. Serum in the chest. Right lung in the acute inflammatory stage.

These stags were taken December 3d, 1860, in exchange for a yoke of oxen sold at the same time to William F. Doane, and kept with Olmstead's diseased herd. They were in the "big team" December 19th.Examined May 9, 1860.

Alanson A. Needham's Herd, New Braintree.

January 3d, 1860, Mr. Needham took three animals from Stoddard's diseased herd into his, which was at that time well. One of these animals was sick when purchased, so that he kept her but three weeks, and then drove her back to Stoddard's, where she died. There was no post mortem. The two steers never appeared sick. On the 30th of January, twenty-seven

days after the introduction of these cattle, a cow of his original herd was taken sick; then one after another drooped till most of his herd were attacked, and eight out of twenty-two died before April 11th. Those which did not die from the disease were killed by the Commissioners, and many of them examined.

Autopsy 18.-Killed a cow which was taken sick on January 30th, 1860. In fourteen days she began to get better. When killed she was gaining flesh, breathed well, and the hair was healthy. She gave ten quarts of milk a day, and in all other respects was healthy, with the exception that she had a slight cough. Percussion dull over the base of the left lung, near the spine, and respiration feeble in the same region. Left lung strongly adherent to the ribs and diaphragm. The long adhesions were smooth, and the pleura, where free from these, was healthy. The lung was of a light pink color, and permeable to air, except at the base, in which was a cyst containing a pint or two of pus. Floating loose in this pus, was a hard mass as large as a two quart measure. This on incision was found marbled in the centre, and presented the appearance of indurated lung detached by suppuration. The cyst seemed to be air-tight, the bronchi being plugged with lymph.-Dr. MARTIN, April 11, 1860.

Autopsy 19.-Killed a cow which had been sick fourteen days and was so sick as to be scarcely able to walk. She was coughing and breathing badly. Hair rough. Percussion dull over both sides and respiration very feeble. Both pleural cavities were filled with serum, and there was a deposit of lymph upon the costal pleura, an inch thick. The right lung was indurated at its base, and the left throughout its whole extent. These diseased portions were brittle, like the liver. Firm adhesion to the diaphragm and ribs near the spine, the lungs being forced back from the parietes elsewhere by the accumulated serum. Nearly one-third of the right lung was compressed by the serum.-Dr. MARTIN, April 11, 1860.

Autopsy 20.-Killed a heifer belonging to Charles Wilcox, a neighbor of Mr. Needham. She was kept with Mr. Needham's herd because, as she coughed, it was feared she might have contracted the disease from these infected animals. She was in fair condition and ate well. There was dulness on percussion, over the base of the left lung, which part adhered to the ribs and diaphragm, and was indurated. On cutting into this diseased lung there were found ulceration, and a head of Timothy grass, four or five inches long. This animal was in every other respect well. Dr. MARTIN, April 11, 1860.

Autopsy 21.-Killed an animal which had been sick four weeks. Right lung indurated at the base and adherent to the diaphragm and costal pleura; in it was a cyst containing a little pus, and a mass of pulmonary tissue, separated on one side only.-Dr. MARTIN, April 18, 1860.

C. P. Huntington's Herd, North Brookfield.

On the 15th or 16th of October, 1859, Mr. Huntington bought a cow of Leonard Stoddard. This cow was taken sick on November 1st, and died on December 5th. No post mortem. December 15th, an animal in Mr. Huntington's herd was taken sick, then one animal after another showed symptoms of severe disease, till scarcely one appeared well. Before the 12th of April, eight out of twenty-two had died. No post mortem. The remaining animals were killed by the Commissioners, and many were examined post mortem.

Autopsy 22.-A cow was attacked on January 1st with a cough, difficulty of breathing and other symptoms of disease, and continued sick till March 1st. On taking her out April 12th, to be slaughtered, she capered, stuck up her tail, snuffed and snorted, showing all the signs of feeling well and vigorous. Right lung firmly adherent to the diaphragm and costal pleura near the spine. No serum. The posterior part of the lung was indurated and contained a cyst, in which was a mass of the size of a two-quart measure, floating in pus. The outer portion of this was of a yellowish-white color, irregular, brittle and caseous. The interior was mottled, or divided into irregular squares, red, and was crushed by pressure like the hepatic substance. The remainder of the lung was apparently healthy, except for a short distance about the air-tight cyst, where it was indurated.-Dr. MARTIN, April 12, 1860.

Autopsy 23.-The animal was attacked on December 15th, and was very sick. In three weeks she appeared well, but still had quite a severe cough, which continued till about the 1st of March, when it became worse and so continued till April 5th, when she calved, after which she improved and appeared as if about to recover, but was killed on the 12th. On examination, the right lung was found adherent to the diaphragm and costal pleura. At the posterior part was a flaccid fluctuating cyst; on opening this, an offensive, decomposing mass of pulmonary tissue was found; otherwise nothing abnormal.-Dr. MARTIN, April 12, 1860.

Autopsy 24.-Killed a heifer, which had coughed slightly for six weeks, but the owner said that he thought no one going into his herd
