592 Mr. J. Wood on Variations in Human Myology. [June 18, 



points d'Anatomie, 1853), who found some of these muscles abnormal in 

 45 per cent, of subjects. The proportionate frequency of the several muscles 

 affexited, however, is much the same. He also found the third to be most 

 frequently affected, as had been observed indeed by the older anatomists, 

 Petsche, Walther, and Heister (in Haller's Disput. Anatom. Select.), as 

 well as by Meckel and Theile. 



22. Flexor carpi radialis. — In three males and two females, two of 

 the males on the right side and the rest on the left only, the tendon of 

 this muscle gave a slip of insertion into the trapezium before being im- 

 planted upon the base of the second metacarpal bone. This has been re- 

 corded by Albinus, Loschge, Fleischmann, Theile, and Hyrtl, and is men- 

 tioned by Henle (Muskellehre, S. 191). 



Flexor carpi radialis brevis seu profundus^* . — In the left arm of a female 

 (No. 28) was found a small specimen of the variety of abnormality de- 

 scribed by the author under this name. It arose from the oblique line of 

 the radius, under the origin of the flexor sublimis, by a falciform aponeurosis, 

 with a fusiform belly 1|^ inch long, and was inserted by a round tendon into 

 that deep process of the annular ligament which is implanted upon the 

 ridge of the trapezium and trapezoid, enclosing the groove for the tendon 

 of the flexor carpi radialis. In the left arm of No. 32 (also a female) a 

 large specimen of the same muscle existed, arising aponeurotic from the 

 oblique line and outer border of the radius, with a fusiform belly ending in 

 a round tendon which crossed deeply and obliquely across that of the flexor 

 longus polKcis, close upon the wrist-joint, to be inserted in a fan-shaped 

 way into the head of the os magnum, almost but not quite reaching to the 

 base of the middle metacarpal bone. This specimen supplies a connecting 

 link between the fusiform muscle attached to the annular ligament of 

 No. 28 (which it resembled in its shape and origin) and the complete^flexor 

 of the middle metacarpal bone described by the author in former papers, 

 which it closely resembles in its insertion. In the same hand the flexor 

 caiyi radialis gave off a slip to the trapezium. In both arms of No. 28 

 the palmaris longus was wanting ; but in No. 32 that muscle was present 



^ While this is going through the press, the author has been favoured by Professor 

 W. Gruber, of St. Petersburg, with the last and several back numbers of the ' Bulletin de 

 I'Acad. Imp. des Sciences de St, Petersbourg.' In the last he claims priority of discovery 

 and publication in the matter of the above-named muscle, which he figured and described 

 in three male subjects in 1859 (in tom. xvii. no. 28, of that periodical ), and which he then 

 named "ilf. radio-carpeus" and " M. radio-carpometacarpeusy The author takes the 

 earliest opportunity of acknowledging this priority as regards himself. He was aware of, 

 and has frequently referred to evidences of Professor Grruber's industry in observation, 

 but he did not recognize his exceeding merits as a discoverer till informed of them by 

 the pamphlets above mentioned. In the last, Professor Gruber himself refers to the 

 publication of an instance of the " M. radio-carpeus " by M. Fano in the ' Bull, de la 

 Soc. Anat. de Paris,' in November 1851, with which he himself did not become ac- 

 quainted before 1859 ! ! The grounds upon which he claims priority in face of this are 

 not convincing ; but he objects to the name given by the author, and announces that 

 the muscle shall from henceforward be called " M. radialis internum brevis (s. minor) !
