Page 64 - AMMONOL possesses marked stimulating and expectorant properties. The well-known cardiac depression induced by other Antipyretics, has frequently prohibited their use in otherwise suitable cases. The introduction of a similar drug, possessed of stimulating properties, is an event of much importance. AMMONOL possesses marked anti-neuralgic properties and it is claimed to be especially useful in cases of dysmenorrhcea.
Page 117 - AMMONOL is one of the products of Coal-tar and differs from the numerous similar products in that it contains Ammonia in active form.. As a result of this AMMONOL possesses marked stimulating and expectorant properties. The well-known cardiac depression induced by other Antipyretics, has frequently prohibited their use in otherwise suitable cases.
Page 114 - Heidelberg4* which gives beautiful results, is as follows: Allow fresh blood to fall drop by drop into a solution of osmic acid (two per cent, acid solution, one part; one per cent, solution sodium chloride, two parts; distilled water, one part). The solution should be constantly stirred while the blood is dropping. Allow the blood and acid to stand over night, and then wash the acid away with distilled water.

Page 99 - The surface is carefully ground on a series of emery papers, mounted on carefully " trued " wooden discs attached to a lathe head, using ultimately the finest grades which can be produced. As the finest commercial papers are much too coarse, it is necessary to prepare the final papers oneself. This is done by washing the very finest slime from the best flour emery, mixing it with a solution of egg-albumen in water, and brushing it on paper specially free from grit. The paper is then allowed to dry...

Page 21 - They increase most rapidly during those seasons of the year when the water is in circulation throughout the vertical. During these periods, not only is food material more abundant ; the vertical currents keep the diatoms near the surface, where there is light enough to stimulate their growth, and where there is abundance of air. Some species of diatom display very strong...
Page 22 - Apbids and Coccids, which are covered with an abundant waxy secretion which can not be readily brushed away, we have adopted the plan of melting the wax. We place the insect on a bit of platinum foil and pass it once over the flame of the alcohol lamp. The wax melts at a surprisingly low temperature and leaves the insect perfectly clean for study. This method is particularly of use in the removal of the waxy cocoon of the pupae of male Coucidie, and is quicker and more thorough than the use of any...
