in the slightest degree in any of these cases, and, \>hile ordinary tactile 

 thermal and pain sensations are abohshed, there remains in this second 

 field a sensibility to a moving contact which leads the author to suspect 

 the existence of fibers of general sensation in the chorda tympani. 

 This peculiar sensation was found to be totally absent, as well as gust- 

 atory sensation, in a case in which the operation had involved the fac- 

 ial as well as the trigeminus nerve. 



The clinical data are conti-oUed by a discussion of the adult anat- 

 omy, the comparative anatomy and the embryological relations, the 

 results of which clear up several vexed questions of peripheral nerve 

 distribution, as well as strengthen to the point of demonstration some 

 of the homologies proposed by recent students of nerve components in 

 the lowliest vertebrates. c. j. h.

Dr. Pinkus describes the hair and its accessory structures and 

 considers that in position and structure these parts are analogous to 

 the scales of reptiles. The human hair preserves the triple-hair 

 structure characteristic of all mammals though the schema is often re- 

 duced to a single hair. A rudimentary scale lies immediately in front 

 of the hair, while the sensory organ under consideration occupies a 

 position behind (i. e. in the acute angle of) the hair. Histologically 

 this knob-like body consists of a broad cutico-papilla with thickened 

 epidermis. This structure, the under surface of whose epithelium is 

 composed of pallisade-like cells, is highly innervated. The theoreti- 

 cal conclusions, which seem perhaps considerably to overbalance the 

 meagre descriptive portions, are as follows : "We have to do, there- 

 fore, with an organ of great antiquity the fundamental form of which 

 is perhaps preserved to us in the form of a genuine epithelial sensory 

 ridge, in Hattcria punctata presumably the oldest reptile.' Our author 

 agrees with Keibel that the hair is "homologous with a specially 

 modified part of a scale." c. l. h.

The author finds no cerebral fissures in the human embryo of 3^ 



to 4 months. The so-called Fissura prima (vordere Bogenfurche of 



His) is not a true fissure, but it might properly be called a "sulcus 



olfactorius" or "fovea olfactoria." Contrary to the idea of His, also.
