Pagina 327 - ... duly registered. The tabulations of the meteorological traces have been regularly made, and these, as well as copies of the eye observations, with notes of weather, cloud, and sunshine, have been transmitted, as usual, to the Meteorological Office.
Pagina 415 - The nerves have been considered so generally as instruments for stimulating the muscles, without thought of their acting in the opposite capacity, that some additional illustration may be necessary here. Through the nerves is established the connection between the muscles, not only that connection by which muscles combine to one effort, but also that relation between the classes of muscles by which the one relaxes while the other contracts.
Pagina 358 - Ewing has already observed, after sudden change of magnetising force the induction does not at once attain to its full value, but there is a slight increase going on for some seconds. (2) The small difference between the ballistic curve of magnetisation with complete cycles, and the curve determined with a considerable frequency which has already been observed is a true time effect, the difference being greater between a frequency of 72 v per second and 5 v per second, than between 5 v per second...
Pagina 3 - Before using the instrument it is essential that the cross wires should be distinctly seen at the punctum remotum of the observer. The adjusted instrument is held in the observer's left hand, which rests on the forehead of the patient, the diaphragm being directed to a luminous source to the right of the observer.
Pagina 416 - I appended a weight to a tendon of an extensor muscle, which gently stretched it and drew out the muscle ; and I found that the contraction of the opponent flexor was attended with a descent of the weight, which indicated the relaxation of the extensor. To establish this connection between two classes of muscles, whether they be grouped near together, as in the limbs, or scattered widely as the muscles of respiration, there must be particular and appropriate nerves to form this double bond, to cause...
Pagina 379 - On the results of an examination of the orientations of a number of Greek temples with a view to connect these angles with the amplitudes of certain stars at the time the temples were founded, and an endeavour to derive therefrom the dates of their foundation by consideration of the changes produced upon the right ascension and declination of the stars by the precession of the equinoxes.
Pagina 129 - ... recognized the blood corpuscles and the filaments of fibrin. On that day biologic medicine was born." "Since the cellular constitution of plants and of animals has been proved, and since cells have become recognized as the essential living elements, the new science of biology has sprung up. ... It has placed in a strong light the immeasurable importance of anatomy, even in the most delicate conditions of the body; and, lastly, it has made us aware of the close similarity of life in the highest...
Pagina 86 - Palermo naturally retreated, as the waters advanced, deeper into the amphitheatre of hills until they found themselves embayed' as in a seine, with promontories running out to sea on either side and a mural precipice in front. As the area became more and more circumscribed the animals must have thronged together in vast multitudes, crushing into the more accessible caves, and swarming over the ground at their entrance, until overtaken by the waters and destroyed.
Pagina 115 - ... who comes before the public ? He who during a long and busy life is exposed to public opinion certainly learns to bear unjust criticism with equanimity, but this comes only through the confidence that our cause is the best, and that some day it must triumph. Such is our hope in our wrestlings for progress in science and art ; such is our hope in our struggles for civil and religious liberty, and in this hope we gradually become hardened against malicious attacks. It is a kind of immunization...
Pagina 406 - Nensholme leads to conclusions differing from the above, aiid it is now, on the contrary, argued that there has been no increase of cancer whatever, as will be seen by the following extract from the " Proceedings of the Royal Society, London ": — • The statistics for Frankfort-on-the-Main enable us to classify cancer in accordance with the part of the body primarily affected. We have therefore classified the returns into two groups, according as the cancer is " accessible " or easy of diagnosis,...
