Ebing, MtLLER, ScHtJ^LE, and others, the author enumerates with 

 considerable detail the early symptoms of such typical nervous and 

 mental diseases as dementia praecox, progressive paralysis, melan- 

 cholia, mania, paranoia, neurasthenia, etc. From this array of evi- 

 dence he concludes, ist. , That every mental disease begins with phys- 

 ical, especially nervous symptoms; 2nd., That no mental disease 

 begins with a pathologically cheerful mood, except mania; 3rd., 

 That in spite of the great differences observable in the fully developed 

 forms of mental disease the early S3anptoms are to a large degree 

 common and uniform. The author pleads for a larger number of pub- 

 lic hospitals for the treatment of nervous affections which, if neglect- 

 ed, may readily develop into insanity. j. c. bell.

This paper has a very wide range and includes the whole of the 

 vertebrates from cyclostomes to mammals. A general scheme is given 

 illustrating the rise of the hypophysis, from which it would appear 

 thnt the organ is invariably formed of an epithelial and a nervous por- 

 tion, the former of which being divided by its micro-chemical reac- 

 tions into a chromophilous and a chromophobio section, of which the 

 former increases and the latter decreases as we rise in the series. The 

 paper is useful contribution to the comparative anatomy of the 

 hypophysis. F. J. C.

 nei Petromizonti. Arch. Anat. EinbrioL, 3, 212. 6 plates and 3 

 text-figures. Florence, 1904. 

 In the first part of the paper after a short historical section the 

 -author describes the post-optic recess, saccus vasculosus, cavum cor- 

 poris mammillaris (of Johnston's terminology) and hypophysis of 

 Petromyzon mari?ius, subsequently comparing the latter with F. fluvi- 

 atilis and P. planeri. He concludes that the hypophysis is a glandu- 

 lar organ, the secretion of which by its action on the blood capillaries 

 has an effect upon the blood pressure. Part II contains a description 

 of the development of the infundibular region in Ammocoetes of from 

 17 to 157 mm. The plates illustrate both parts of the paper.
