Shimek's criticism of the aqueous origin of 

 Loess ' is answered by Professor G. Frederick 

 Wright. Mr. Paul W. Prutzman discusses 

 the ' Chemistry of California Petroleum,' and 

 the number concludes with an article by Pro- 

 fessor Lawrence M. Lambe, ' On the Tooth- 

 Structure of Mesohippus westoni (Cope),' 

 which is illustrated by one plate giving four 

 views of an upper molar of this primitive 

 species. 



The American Naturalist for March con- 

 tains the following articles : ' The Anatomical 

 Changes in the Structure of the Vascular 

 Cylinder, Incident to the Hybridization of 

 the Catalpa,' by D. P. Penhallow; 'The Oc- 

 currence and Origin of Amber in the Eastern 

 United States,' Arthur Hollick ; ' Fresh-water 

 Ehizopods from the White Mountain Region 

 of New Hampshire,' J. A. Cushman and W. 

 P. Henderson ; and ' The Reactions of the 

 Pomace Fly (Drosophila ampelophila Loew) 

 to Light, Gravity and Mechanical Stimula- 

 tion,' by F. W. Carpenter. There are, besides, 

 reviews of scientific literature. 



Arteriosclerosis in its relation to diseases 

 of the nervous system is the subject of the 

 opening paper in the May issue of the J ournal 

 of Nervous and Mental Disease. Dr. E. D. 

 Fisher discusses the clinical aspect, and Dr. 

 Harlow Brooks summarizes the pathology, 

 with reports of three illustrative cases, one of 

 syphilis of the cerebro-spinal axis, one of 

 arteriosclerosis of the brain and spinal cord 

 occurring in alcoholism, and one of acute 

 arteritis occurring in vessels of the central 

 nervous system in rabies. Drs. W. G. Spiller 

 and C. H. Frazier follow with the presentation 

 of some original views on the subject of nerve 

 anastomoses. They have experimented in this 

 line in the treatment of cerebral palsies, and 

 their suggestions open up a field in neurolog- 

 ical surgery that seems to be full of promise. 

 Dr. Spiller also contributes a short illustrated 

 paper, being mainly the report of a case which 

 came under his observation and seemed to 

 offer valid evidence for the location of the 

 fibers of temperature and pain within the 

 tracts of Gower. Dr. Jas. W. Wherry writes 



on the curability of epilepsy, and takes an 

 optimistic view of the question, conditioned 

 on beginning treatment promptly upon the ap- 

 pearance of the disease. Plis idea of the re- 

 quirements in such treatment consists of ' A 

 study of each case individually; special adapta- 

 tion of drugs to individual conditions; per- 

 sonal supervision and individualization of diet, 

 absolute change of environment.' The pro- 

 ceedings of the New York Neurological 

 Society for December 6, 1904, and of the 

 Philadelphia Society for December 27, 1904,- 

 are reported.
