been an induration of the thyroid gland. The author speaks of the 

 disease as a connective-tissue dystrophy, a fatty metamorphosis of 

 various stages of completeness, occurring in separate regions, with 

 symptoms suggestive of an irregular and fugitive irritation of the 

 nervous trunks — possibly a neuritis. 



Wood's Reference Hand-book Supplement. 



The Supplement embraces 1076 quarto pages of closely printed 

 matter which, on the whole, is of excellent quality and will serve to 

 bring the work down to date. Several neurological articles have 

 already been noticed. It is obviously impossible to offer even a sum- 

 mary of all. The following jottings may, however, prove useful : 



Articles on the Brain in the Reference Hand-Book. 



Among the many useful articles in the supplement to Wood's 

 Reference Hand-book of the Medical Sciences are two by Professor 

 B. G. Wilder, on the brain. The first of these is a supplement to his 

 paper in the eighth volume of that work. After illustrating the prin- 

 ciple enforced in his article in an earlier volume of this journal, that 

 it is each author's duty to correct his own mistakes as soon as discov- 

 ered, he enters upon questions of nomenclature. Among other sug- 

 gestions are these : Neuron might better be associated with axon and 

 enteron as a name for the whole neural axis and neuraxis would be 

 appropriate instead of axis cylinder. 



Professor Wilder suggests that the bulbs, their crura, the olfactory 

 portion of the precommissure and a part of the aula might be recog- 

 nized as constituting a sixth definitive segment (Rhinencephalon); 

 but — unless the word encephalon in composition is to be shorn 

 altogether of segmental significance — it should no more be used 

 for a vent;-al portion of a region than for a dorsal portion, e. g. 

 the cerebellum, without the supporting preoblongata. Very nat- 

 urally he objects to the use of the term " Rhinencephalon," 

 by Sir William Turner in a third sense. We ma'y add that the 

 confusion in nomenclature is here absolutely intolerable. One who 

 is indisposed to apply a term of his own coinage for all parts of the 

 olfactory apparatus may have a choice and varied assortment of 

 names for every part. The German usage seems to embrace under 

 the term olfactory lobe, a projecting bulbus, a connecting peduncle 

 and an eminence on the cerebrum, the tuber. Others use lobe as 

 restricted to the tuber, which is also termed the tract. In other cases 

 the word tuber is applied to the bulb.
