tion, Movement ; Vocal Organs ; Organs of Reproduction, etc. The author 

 maintains that there has been an evolution of organs as well as of animals, and 

 that he who desires to understand the most complicated organs must first know 

 the structure of such as are more simply constructed. 



The Dissection of the Frog. By J. Cossar Ewart, M.D. 

 Directions for the Examination of the Amceba, Para- 



moecium, Vorticella, Hydra, Lumbricus, Hirudo, Asterias, and Echinus. By 

 J. Cossar Ewart, M. D., and J. Duncan Matthews. 



The Dissection of the Skate. By the same. (Edinburgh : 



James Thin. 1884). Price is. 6d. each. 



In the above works, which are published for the use of Students in the 

 University of Edinburgh Laborator}-, full instructions for dissection and exa- 

 mination of the object, with directions for making drawings of the various 

 parts, are given on the left-hand page, the right-hand page being left blank, 

 we suppose, for the drawings. These books appear to us to be most useful. 



Johnstone's Student's Atlas of Bones and Ligaments. 



By Charles W. Cathcart, M.A., MB., F.R.CS., etc., and F. M, Caird, 

 M.B., F.R.CS.E. (Edinburgh: W. and A. K. Johnstone. 18S5.) Size 

 of page, 14^ in. by II in. Price 15s. 



This fine work contains 30 plates, each accompanied by descriptive letter- 

 press. On each plate we notice also that the origins of the muscles are 

 marked in red, and their insertions in blue, which has been supplemented by 

 printing the names of the muscles in corresponding ink, and in washing a 

 shade of blue over the articular surfaces. A similar shade has been used to 

 express the various ligaments, and in some cases a mottling of red has been put 

 in to draw attention to sections through the bone. Letterpress has been used 

 on each plate to indicate the various points which the student should remember.

 sity of Pennsylvania. Edited by N. A. Randolph, M.D., and vSamuel G. 

 Dixon, pp. 88. (Philadelphia, U.S.A. : J. B. Lippincott. 1885.) 



The papers forming this little volume are records of facts of interest brought 

 to light in the course of physiological study, and embrace Notes on the Faeces 

 of Starch-fed Infants ; a Study of the Distribution of Gluten in the Wheat- 

 grain ; on the Digestion of Raw and Boiled Milk ; on the Nutritive Values of

The Essentials of Histology, Descriptive and Practical, 



for the Use of Students. By E. A. Schafer, F.R.S. pp. x. — 245. (London: 

 Longmans, CJreen, and Co. 1885.) Price 6s. 



Those who are not already the happy possessors of Dr. Schafer's large and 

 more elaborate work will doubtless be much pleased with this elementary and 

 condensed one, which is sure to prove of much value in class teaching. For 

 the convenience of students, it is divided into forty-two lessons, each of which 

 may be supposed to occupy the class from one to three hours. Each lesson 

 takes a special list of tissues for microscopical examination, clear and detailed 

 directions being given for their preparation.
