Three Important Books 



Mallory's Pathologic History '"^ItZZe 



Dr. Mallory presents pathology biologically. First he ascertains the cellular elements ont 

 of which the various lesions are built up ; then he traces the development of the lesions 

 from the simplest to the most complex. He so presents pathology that you are able to 

 trace backward from any given end-result, such as sclerosis of an organ (cirrhosis of the 

 liver, for example), through all the various acute lesions that may terminate in that par- 

 ticular end-result to the primal cause of the lesion. The book is based on the study of the 

 lesions themselves. There are 683 illustrations, 134 in colors. 



Octavo of 677 pages, with 497 figures containing 683 original illustrations, 124 in colors. By Pbank B . 

 Mallory, M.D., Associate Professor of Patliology at Harvard Universitj Medical School. Cloth, 85.50

Davis* Nasal Accessory Sinuses 



This book is based on the study of 290 lateral nasal walls, presenting the anatomy and phys- 

 iology of the nasal accessory sinuses from the sixtieth day of fetal life to advanced maturity. 

 It represents the original research work and personal dissections of Dr. Davis at the Daniel 

 Baugh Institute of Anatomy of Philadelphia and at the Friedriohshain Krankenhaus of 

 Berlin. In order to complete the series Dr. Davis had to develop a new technic hy which 

 the accessory sinus areas could be removed en masse at postmortem, and still permit of 

 reconstruction of the face without marked disfigurement. The tables of averages give you 

 the age, size of ostia, origin, thickness of septum, and anterior and posterior walla, 

 vertical, lateral and posterior diameters, and relation to the nasal floor.

Wells' Chemical Pathology 



NEW (.2d) EDITION 



This work deals with the chemical changes which take place in pathologic conditions. 

 It Ireats of the causes of disease, and so provides the first step in their treatment. It dis- 

 cusses the cell (proteins, ionization, colloids, osmotic pressure, etc.), enzymes, nature and 

 action ; autolysis; chemistry of bacteria andparasitea and their products; immunity, agglu- 

 tinins, precipitins, toxins, antitoxins, phytotoxins, zootoxins, hemolysis, serum cytotoxins, 

 inflammation, blood diseases, edema, retrogressive processes, (necrosis, cloudy swelling, 

 gangrene, rigor mortis, various degenerations, etc.); calcification, pigmentation, tumors, 

 metabolism, uremia, gout, diabetes, auto-intoxication, ductless glands (thyroid, adrenals, 

 hypophysis, thymxiB, etc.). This new edition is right up to date.
