Excerpt from A Text-Book of Medical Chemistry and ToxicologyON admission to the medical college the student is expected to have some knowledge of physics. Experience shows that a part of this information - concerned with chemical questions and having toxicologic and therapeutic interest - needs to be refreshed and enlarged.The remarkable developments of physical science in recent years have furnished the practical sciences with working princi ples of great value, and are being applied successfully to biologic problems in bacteriology, toxicology, and pharmacodynamics. Cryoscopy, osmotic pressure, electrolytic dissociation, mass action, radio-activity, have not been recognized hitherto as part of the preparatory studies, and hence should find a place in the medical text-book to the extent, at least, of a preliminary state ment of the principles involved.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
