SCIENCE. 



379 



noted that these researches deal with the 

 finest structures of the digestive tract. 



Mr. C has made extensive researches in 

 general anatomy, especially in vertebrate em- 

 bryology. His experiments on the formation 

 of the embryo in fish and amphibia are well 

 known. ^More recently he has taken up the 

 study of histogenesis, especially of tibrillated 

 muscle cells and their nuclei. At present he 

 is engaged upon a study of spermolysins and 

 ovolysins. 



Mr. D has been making contributions to 

 our knowledge of the anatomy of the spleen, 

 especially its framework, but is better known 

 through the work of the last year and a half, 

 conducted chiefly with Professor Ehrlieh in 

 Frankfurt, upon the nature of poisons which 

 act upon the blood, especially snake poison. 

 His studies have attracted international at- 

 tention and have a wide bearing upon blood 

 poisons in general. 



Mr. E has made a special study of the 

 anatomy of the ducts and blood-vessels of 

 the pancreas of the hog and their origin in 

 the embryo and has published part of the re- 

 sults. He is now engaged upon the study of 

 the framework and wandering cells of the 

 mucous membrane of the human stomach. 



Mr. F is engaged upon the study of the 

 arrangement of the connective tissues in the 

 mammalian larynx and the study of the his- 

 togenesis of the laryngeal glands in the pig. 



Mr. G is engaged upon the study of the 

 morphology of the head in vertebrates, and 

 on the study of the changes in the structure 

 v{ the mucous membrane of the stomach fol- 

 lowing the operation of gastroenterostomy. 



Mr. H is making important observations in 

 methods of staining nerves with methylene 

 blue and with Bethe's neuro-fibril method. 

 These studies have been concerned chiefly 

 with the degeneration of axones and nerve 

 endings after nerve section or local pressure; 

 and further with the effect of electrical stimu- 

 lation on the structure and vital staining 

 properties of nerve endings. 



Mr. J has worked out the distribution of 

 the blood-vessels in the labyrinth of the ear of 

 f^UJi scrofa domestirus, the results appearing in 

 the Decennial Publications of the University. 



11*- is now engaged upon the study of the struc- 

 ture and function of the strui vascularis. He 

 spent a great deal of time and care in the 

 I>roi)aration of casts and injections to form 

 material for his special course. 



THE DEPARTMENT OF NEUROLOOY. 



Mr. A is at work on the change in the per- 

 centage of water in the nervous system of the 

 white rat during the period between birth and 

 full maturity. 



Mr. B is making a study of the relative 

 activity of the white rat at different ages and 

 at different hours of the day. 



Mr. C is working on the effects of lecithin 

 on the growth of the central nervous system. 



Mr. D : on the law for the distribution of 

 the nerve fibers which innervate the leg of the 

 frog. 



Mr. E : on an enumeration of the medullated 

 nerve fibers in the dorsal and ventral roots of 

 the spinal nerves of man. 



Mr. F : on the psychical development of the 

 young white rat correlated with the growth of 

 its nervous system. 



Miss G : on the mode in which the white 

 substance of the spinal cord of the rat in- 

 creases in area. 



Mr. H: on the healing of wounds of the 

 brain at different ages between birth and ma- 

 turity. 



Mr. J : on the axone reaction as obsert-ed in 

 the nucleus of the third cranial nerve of the 

 white rat. 



THE DEPARTMENT (IF BOTANY. 



Mr. A is engaged in studying problems 

 connected with the origin and evolution of seed 

 plants. A book, just going through the press, 

 iov the first time organizes the subject for the 

 lienofit of advanced and research students. 



Mr. B is at present investigating the prob- 

 lems of fertilization amoug the lower plants. 

 The results are distinctly pushing out the 

 boundaries of our knowledge of one of the 

 most fundamental life-processes. 



Mr. C is investigating cytological problems 

 among plants, and is completing an important 

 • •ontribution to our knowledge of the methods 

 of nuclear division. 



Mr. D is a large contributor to plant ecol- 

 ogy, and is now engaged in organizing the
