Laboratory Manual and Text-Book of Embryology. By Charles 

 W. Prentiss, Ph. D., Professor of Microscopic Anatomy, North- 

 western University Medical School, Chicago. Large octavo of 400 

 pages, with 368 illustrations, 50 in colors. Just Out. 



Professor Prentiss' new work is the only recent single volume describing 

 the chick and pig embryos usually studied in the laboratory, at the same 

 time giving you a concise, systematic account of human embryology. 

 The descriptions of the embryos to be studied in the laboratory are con- 

 cise, yet they are profusely illustrated , the majority of the pictures being 

 original. It is the only comparatively brief text in which a large num- 

 ber of original dissections of pig and human embryos are described and 

 illustrated, and in which directions are given for making dissections of 

 the nervous system, viscera, face, palate, and tongue of these embryos. 

 Of the same embryos from which series of transverse sections have been 

 made illustrations are given, showing the external form and internal 

 structure. The student will thus be enabled to determine the position 

 and plane of section of each section studied. There are nearly 400 

 superb illustrations.
