§ 1448. Acceptance of the new nomenclature. — The terms of description em- 

 ployed in the present work have been, upon the whole, commended by The Medical 

 Record (May 13, 1883, Feb. 10, 1883), The Medical and Surgical Reporter (March 34, 1883), 

 Science (May 11, 1883), Nature (May 24, 1883), The American Naturalist (July, 1883), and 

 by otlier medical and scientific journals. Meson and its derivatives mesal and mesad, 

 ectal and ental, lateral, transection, Tiemisection, etc., occur in The American Journal of 

 Neurology and Psychiatry (I, 46, 50, 55, 101-104), and The Journal of Nervous and Mental 

 Disease (XI, 1-38), and are employed more or less uniformly by our colleague, Prof. J. H. 

 Comstock (A, B), by Langley and Sherrington {1, 55), Morton and Dana (Med. Record, 

 July 8. 1883, p. 5), Murie (Zoological Transactions, VllI, 183), Sachs (Neurologisches 

 Centralblatt, Dec. 15, 1885, p. 549), Seguin (S, 33, 33, 33, etc.), Spitzka, (21, 423, 47?), 

 and T. B. Stowell {1, 2). Dorsal, ventral, lateral, cephalic and caudal are now commonly 

 used, and their adverbial forms, dorsad, laierad, etc., are not infrequent. Cephalic and 

 caudal are, of course, objectionable theoretically, because they are employed for the desig- 

 nation of special parts as well as of general body regions. But as long as medical writers 

 persist in using anterior and posterior for ventral and dorsal, the comparative anatomist 

 cannot employ the former without risk of misapprehension. 



The following is a recent illustration of the ambiguity of descriptive terms applicable 

 to the human body alone. The writer spoke of the " transverse diameter" of the uterus ; 

 fearing that this might be interpreted as dextro-sinistral, he qualified it by the words 

 " antero-posterior ; " but this might mean either caiido-cephaXic or dorso-ventral. 



The revised encephalic nomenclature has met with unexpected favor from working 

 neurologists Uke Osborn (1, 2), Spitzka (7), and Wright (Standard Natural History, HI, 

 pp. 37-35), and the first named permits us to say that he lias found " the greatest advan- 

 tage from the use of the brain terminology in practical work." As stated in the senior 

 author's paper (63, 336), Prof. T. Jeffery Parker, of New Zealand, had independently 

 employed KocXia as the basis for ventricular designations (A and 2), and one of his terms, 

 mesoomle, is simply a paronym of mesoccdia. 



§ 1444 (§146.) Nippers. — Besides the ordinary surgical bone forceps, there are the 

 dental " wedge-cutters," which closely resemble the nippers, but are highly polished and 

 provided with a spring for separating the handles ; they cost about $3.35.
