Braasch's Pyelography 



Dr. Braasch's new work is the first comprehensive collection of pyelograms 

 showing both normal and pathologic pelvic and ureteral outlines. You get 

 here 296 skiagrams selected from several thousand made at the Mayo Clinic 

 during the past five years. These pyelograms, together with the clear de- 

 scriptions, constitute an admirable aid to the differential diagnosis of the 

 various conditions affecting the renal pelvis. The characteristic pelvic out- 

 line in each disease is first shown you by the excellent pyelograms ; then 

 Dr. Braasch interprets the pyelograms for you in diagnostic terms. In ad- 

 dition, you get the history and development of pyelography, the exact tech- 

 nic, selection of the medium, preparation of the solution, accidents, sources 

 of error, results, gas pyelography, etc. 



Octavo of 323 pages, with 296 pyelograms. By William F. Beaasch, M.D., The Mayo Clinic, Rochester, 

 Miss. Cloth, S5.00 net 



Prentiss' Embryology 



Professor Prentiss has given you here both a laboratory manual and a de- 

 scriptive text-book. It is the only recent book describing the chick and pig 

 embryo. You get a large number of original dissections of pig and human 

 embryos, giving directions for making dissections of the nervous system, 

 viscera, face, palate and tongue. Of the same embryos from which series 

 of transverse sections have been made, illustrations are given, showing you 

 the external form and internal structure. A feature of the book is the large 

 number of illustrations. 



Large octavo of 400 pages, with iOO illustrations. By Chahles W. Pkentiss, Ph.D., formerly Professor of

Mallory's Pathologic Histology 



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

 elements out 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 particular 

 end result to the primal cause of the lesion. There are 683 illustrations. The 

 124 colored illustrations are printed directly in the text. There are no trouble- 

 some inserts. 



Octavo of 677 pages, with 497 figures, containing 673 original illustrations, 124 in colors. By Frank B. 

 Mallory, M.D., Associate Professor of Pathology at Harvard Medical School, Boston.
