MEETINGS OF THE SECTIONS.

NORTH EASTERN SECTION.

A meeting for the purpose of organizing a local section of the American Chemical Society was held in Boston at the Parker House, on February 4th. About 150 chemists were in attendance. An application for a local charter was signed; and the following officers were elected: President, A. A. Noyes, Massachusetts Institute of Technology; Vice-President, L. P. Kinnicutt, Worcester Polytechnic Institute; Treasurer, B. F. Davenport, Boston; Secretary, W. R. Whitney, Massachusetts Institute of Technology. An Executive Committee was appointed consisting of the above officers, together with John Alden, Pacific Mills, Lawrence, Mass.; A. D. Little, Boston; H. Carmichael, Boston; John Shaw, Boston; and H. P. Talbot, Massachusetts Institute of Technology. It was voted that the territory covered by the section comprise the states of Massachusetts, New Hampshire, Maine, and Vermont. A Committee on By-Laws was appointed by the president.

The second meeting was held at the Parker House, Boston, March 25th, with 150 members present. A paper, illustrated by experiments, was presented by A. A. Noyes, the subject being "The Dissociation Theory of the Condition of Salts in Solution and Some of Its Important Applications." After the discussion of this paper, a recess was taken to furnish opportunity for social intercourse. A second paper was then presented by John Alden, Chemist of the Pacific Mills, Lawrence, on "The Production of the Direct Azo Colors on the Fiber." This was also illustrated by experiments and by a large number of

samples of the dyed colors. Members were also presented with a folder, specially prepared for the occasion, containing samples of the dyed goods with descriptions of the processes of preparation, etc. It was voted at this meeting that the name of the section be made the North Eastern Section. Some new apparatus was exhibited by Richards & Co., of New York.

W. R. WHITNEY, Secretary.

CINCINNATI SECTION.

The March meeting of the Section was held in the Lloyd Library on Tuesday, March 15th, with twenty members and several guests present, and Professor O. W. Martin in the chair.

The chairman exhibited a number of specimens of gunpowder and guncotton, and in this connection gave some interesting information as to their physical and technical properties. Mr. Louis Werk then read a paper on the determination of sulphur in coal, giving in tabulated form the results of numerous analyses of a certain specimen of coal, carried out according to the methods of Eschka, Wiley, and Carius. The paper included a series of experiments undertaken to determine the amount of barium chloride which is precipitated along with barium sulphate from sulphuric acid solution.

Dr. R. Monroe McKenzie then read a paper on "Some Double Chlorides of Ferric and Ferrous Iron with Some Aromatic Bases," viz., aniline and the three toluidines.

Dr. Alfred Springer made an informal report on the qualitative analyses of two distilled waters which had been sent to his laboratory the day before.

The first water, when evaporated to dryness, left a white residue or rather coating on the glass dish; when heated, it gave a distinct odor of coniferine. Taking some coniferine to make comparative tests, it was found that both-besides showing the usual reaction with phenol and hydrochloric acid-turned solutions of potassium permanganate a bright cherry red, and potassium manganate an emerald green; even traces of coniferine had this effect. Upon inquiry it was ascertained that the distilled water had been stored in a cypress tank.

The second water, very clear in appearance, as soon as heated, produced a black scum, which adhered to the sides of the con

taining vessel when evaporated to dryness. The residue proved to contain copper in such quantity that the residue from one liter was sufficient to plate a platinum dish besides serving for a half dozen different tests. In order to compare the delicacy of the well-known reagents, Dr. Springer found that hydroxylamine hydrochloride showed the presence of copper in the original water, whereas it required evaporation to about one-sixteenth of the original volume to produce either the ammonia or the ferrocyanide reaction.

Inquiry developed that the water had been pumped directly from an artesian well into a still. Undoubtedly, as Dr. Springer remarked, the free carbon dioxide as well as that liberated from the bicarbonates in the water, produced the solvent action on the copper pipes.

On motion, the meeting adjourned.

S. WALDBOTT, Secretary.

COLUMBUS SECTION.

The following papers were presented at the regular meetings held in March and April:

I. "The Results of the Chemical Investigation of the Water of the Scioto River," by Professor N. W. Lord.

This work was carried on under the auspices of the State Board of Health, and will be published by the Board. The object in view was a critical study of the river waters of Ohio. The result of a large number of analyses of waters taken from different places and at different periods, was given and interesting conclusions drawn.

2. "The Nerve Cell as Presented by the Newer Methods of Research," by Dr. A. M. Bleile, an associate member of the Section.

3. "The Solution of Chemical Problems," by O. R. Flynn. The author gave his methods of presenting this subject to students.

4. "Effect of an Excess of Reagent in the Precipitation of Magnesium Ammonium Phosphate," by C. W. Foulk. The following is a brief abstract of the paper:

A series of experiments was made by precipitating fixed amounts of magnesium ammonium phosphate under carefully

regulated conditions which were made to agree as clearly as possible with ordinary analytical operations. The time of standing after precipitation and before filtration and the amount of reagent added were varied. Filtrations were made varying from two hours to half an hour after precipitation. In every case it was found that complete precipitation was effected provided sufficient reagent was added. Decreased time of standing required the addition of more precipitating reagent. No essential difference in the excess of reagent required was noted between precipitating Mg ions with PO, ions and vice versa, or between large and small amounts of precipitate in proportionate volume, excepting in the case of precipitating very small amounts of sodium hydrogen phosphate with magnesium chloride. Here the results seemed to show that relatively more magnesium salt is required to effect complete precipitation in half an hour. A number of comparative results was also given to show that in the presence of molybdic acid, i. e., where the PO, ions had been separated with molybdate solution-a very much smaller excess of Mg ions is required to effect complete precipitation. The author desires to carry the investigation somewhat further before publishing the results as a whole.

Messrs. E. F. Watson and A. C. Ehrenfeld were duly elected members of the Section. WILLIAM MCPHERSON, Secretary.

WASHINGTON SECTION.

The regular monthly meeting was held on March 10, 1898. Dr. E. A. de Schweinitz presented a paper on "The Pasteur Milk Laboratory of Washington." The speaker first reviewed briefly some of the ways in which milk can become infected, either from the fact that the animals are dirty and the stables in a filthy condition, or from the carelessness of the milkers, the dirty condition of the pans and pails and the use of impure water for washing these utensils. Attention was also called to the fact that dogs, cats, rats, mice, etc., which often obtain access to the place where the milk is ordinarily kept in the country, may affect the milk, as it is well known that these animals are often carriers of the germs of disease. In view of all these well-known dangers, and especially the fact that many outbreaks of typhoid fever have been traced directly to an
