no hint. The two cephalic pairs of "accessory lobes" are, in this 

 case, associated with the first spinal, the second spinal arises from the 

 third pair and the third from the five remaining. The sensory root of 

 the third spinal is more than ten times as as large as the motor and it is 

 from the three branches of this nerve that the free rays are innervated. 

 The rays are at first associated with the others by a web which is ab- 

 sorbed during development, proving that the free rays are of secondary 

 origin. The nerves in the free rays form a plexus beneath the surface 

 of the epidermis. Nerve fibres from the plexus pass between the cells 

 of the inner layer of the epidermis, where they divide, some ending 

 free and others are directly connected with spindle cells that extend to 

 the cuticle. The office of the free rays seems to be the detection of 

 food and tactile sensation incident to locomotion.

Edinger's Bericht.^ 



Edinger's admirable Review of the anatomical literature of Neu- 

 rology for 1893 ^'^^ 1894 is at hand. This work grows in importance 

 from year to year until now it is well-nigh indispensible. The present 

 number contains 54 large pages of closely printed matter. In the brief 

 introduction the author congratulates the science on the number of in- 

 vestigators who are entering this field ; but laments the growing tend- 

 ency to publish brief communications, often hastily prepared, while the 

 number of larger, monographic works is diminishing, and especially 

 he utters a timely warning against the still greater evil of basing far- 

 reaching generalizations on work of that fragmentary character.

Physician's and Surgeon's Pocket Dictionary.* 



This little book is really too brief both in the number and character 

 of the definitions to be of much use to physicians or anybody else. 



Anatomy of the Brain of Craniates.^ 



The author presents a variety of (chiefly anatomical) data from 

 Petromyzon, dipnoid, and selachian brains in support of views
