varieties of palmaris longus; the third is from the presence of both 

 longus and accessorius ; the ninth, tenth, eleventh, and twelfth may be 

 varieties of the flexor carpi radialis brevis ; and the nineteenth is most 

 likely a form of flexor accessorius. 



One other remarkable variety occurred as a large expanded muscle, 

 half the size of the flexor carpi ulnaris. It arose by two heads — one a 

 tendinous, or rather fascial slip from the point of the internal condyle 

 of the humerus, superficial to the pronator muscles ; the second head 

 arose fleshy and tendinous from the inner edge of the ulna, under 

 cover of the flexor carpi ulnaris, and extended for nearly the lower 

 two-thirds of that bone ; the two origins were separated above by the 

 ulnar nerve, as no ulnar artery existed in the subject, but they soon 

 united. The insertions of the muscle were two fold : first, by a tendon 

 to the palmar fascia ; and, secondly, by a much stronger band, likewise 

 tendinous, into the abductor pollicis. 



In a male subject, with a large normal palmaris longus, the acces- 

 sorius arose by a flat tendon from the internal condyle, and passing 

 downwards, became fleshy, and was inserted by a two fold attachment- 

 one into the annular ligament and palmar fascia, and a second into the 

 abductor minimi digiti ; these insertions were quite separate, the 

 former being tendinous and the latter fleshy. 



5. The flexor carpi radialis presented a radial origin below the tubercle 

 of that bone, and in another case from the second head of the flexor 

 sublimis digitorum. It likewise exhibited a coronoid origin, which in 

 one case was separated by the median nerve from the condyloid head ; 

 and . in another case the largest part of the fleshy mass arose from the 

 deep surface of a process from the biceps tendon. The former cases 

 were probably instances of the coalition between the normal flexor and 

 the deep radial flexor of Wood. (For the nature of the slip from the 

 coronoid process, see the "Journal of Anatomy andPhysiologv," vol. ii. 

 3STo. 1, p. 8). 



6. A very distinct example of the middle head of the gastrocnemius 

 occurred in another subject similar to the one described in my former 

 paper. 



7. The passage of the lesser pectoral over the coracoid process I 

 have referred to in a paper in the "Journal of Anatomy " for May, 

 1867, and I have found, since that paper was written, out of 29 ex- 

 tremities that its tendon passed over the coracoid process in 12. Of 

 these it was attached to the triangular ligament in five, pierced through 

 it in the remaining seven, and was attached to the supra- spinatus 

 tendon, to the capsular ligament, and the head of the humerus in the 

 remainder. In that paper, I showed that the coraco-glenoid fasciculus 

 of ligament first described by me in the " Proceedings of the Royal 

 Irish Academy," vol. ix., pi. iv. fig. 1, a, was the representative of the 

 prolonged tendon, and was absent in cases where the prolonged tendon 

 existed. 



8. In the left hand of a thin old male subject, the in dicial tendon of 

 the flexor sublimis became suddenly fleshy opposite the metacarpo-
