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



of the perforans supplied the perforated tendon of the little toe. In the 

 right foot of No. 11a long slip from the Jlexor-longus-digitorum tendon 

 joined that of the flexor hrevis going to the middle toe — as before described 

 with the varieties of the former muscle. In the left foot of the same sub- 

 ject a similar tendinous slip to the flexor brevis tendon of the middle toe 

 arose from the fibres of the accessorius. 



Out of 68 males the outer tendon of iht flexor brevis digitorum has been 

 found absent in 10, viz. 6 in both feet, 3 in the right, and 1 in the left 

 only. Out of 34 females it has been found absent in 5, viz. in both feet in 

 4, and in 1 in the right only. This gives a proportion of 15 per cent, and 

 an exact equality in the two sexes. In 4 of these, viz. 3 males and 1 

 female, a substitutory slip of muscle and tendon arose from the corre- 

 sponding tendon of the perforans, as in the Quadrumana. In one this was 

 connected partly with the fibres of the accessorius, and partly had a separate 

 origin from the tubercle of the calcaneum. 



54. Abductor halliicis. — A considerable slip from this muscle to the 

 second toe, arising with the front fibres, and inserted into the base of the 

 first phalanx, as first found and described by the author in his paper of 

 last year, was seen this year in three males and one female. In one of the 

 males and in the female it was found in both feet, in one male in the right 

 foot, and in the third in the left foot only. A similar slip is said by Meckel 

 to be found in the foot of the White Bear. 



Out of 40 males this slip has been found in 5, in 2 in both feet, in I 

 in the right, and in 1 in the left foot only. Out of 30 females it has been 

 found in 1 only, in both feet. 



55. Opponens minimi digiti. — This muscle, first pointed out by Henle 

 as frequently present in the human foot, has been noted this year in 6 sub- 

 jects out of 36, in 1 male and 5 females. In 4 it was found in both feet, 

 in 1 in the right and in 1 in the left foot only. In 1 female in last year's 

 series it was found, remarkably large, in both feet. The author has found 

 this muscle largely developed in the Orang. In the Bonnet-^Ionkey it 

 was not present. It is figured in Cuvier and Laurillard's plates as very 

 large in the foot of the Lion and Panther. 



56. Sundries. — Besides the three-headed gastrocnemius already de- 

 scribed, we have in this column, in the male (No. 4), an entirely detached 

 portion of the iliacus internus, arising from the middle of the iliac crest 

 by a thin tendinous aponeurosis, forming a flat muscular slip, which was 

 inserted into the common tendon of the psoas and iliacus muscles. In 

 both feet of the female (No. 20) the abductor minimi digiti was provided 

 with two distinct tendons. In the left leg of the female (No. 22) a con- 

 siderable fleshy slip from the adductor hrevis joined the tendon of the 

 obturator externus. In the right foot of the female (No. 27) the tendi- 

 nous slip from the insertion of the tibialis posticus to the outer cuneiform 

 bone, which usually gives part origin to the flexor brevis halluciSy passed 

 wholly into that muscle without being connected with the cuneiform. In
