caneum of Grantzer, arising by a flat, bipenniform, muscular belly from 

 the posterior tibial fascia below the tibial origin of the soleus, and 

 inserted by a flat spreading tendon, whicb crossed obliquely the post- 

 maUeolar tendons into the os calcis in front of the tendo-achillis. From 

 its outer border was given off a spreading aponeurosis, which was 

 attached to the hinder border of the outer malleolus, almost like that 

 seen in figure 7. In the left leg of a female subject was found the 

 jperforatus tendon of the little toe, arising from a separate triangular- 

 shaped muscle, which was attached to both the tubercles of the cal- 

 caneum between the superficial muscles and the accessorius, like that 

 described in the author's former papers. 



In the left arm of another muscular male subject two abnormalities 

 were found, viz. a third head of the pronator radii teres, arising with 

 the fibres of the hrachialis anticus at the junction of the middle and 

 lower thirds of the humerus. The median nerve and ulnar vessels 

 passed between the abnormal and condyloid heads, and the radial 

 artery came oft" high in the upper arm. No supra-condyloid process 

 was found on the bone (as described by Gruber in such a case), although 

 carefully looked for. The other abnormality was a high muscular 

 origin of the abductor minimi digiti, arising from the fascia covering the 

 inner flexor muscles of the fore arm by a single penniform head, and 

 joining partly with the normal abductor, and partly inserted by a sepa- 

 rate tendon into the base of the first phalanx of the little finger. 



The author is indebted also to Mr. J. Gralton, of the Dreadnought 

 Hospital, for some clever sketches of three abnormalities, one of a detached 

 slip of the 'pectoralis major, arising from the anterior end of the fifth rib, 

 and inserted behind the sternal fibres into the fascia covering the coraco- 

 brachialis, an inch or so below the coracoid process ; another, of an 

 "accessorius ad flex or em pollicis longum''^ of Grantzer, the tendon of ^ 

 which, after being first connected by a broad aponeurosis with the 

 muscular belly of the flexor longus poUicis, was then divided into two 

 slips, one of which joined the tendon of the last-named muscle, and the 

 other the indicial tendon of the flexor profundus digitorum (as in sub- 

 ject 9 previously described). The third was a small fusiform muscular 

 slip, found on the deep surface of flexor hrevis hallucis, arising by a 

 pointed tendon from internal cuneiform bone, and inserted by another 

 round tendon into the abductor and inner head of the flexor brevia 

 hallucis, close to the sesamoid bone. It seems to represent the " inter - 

 OSS eus palmar is volaris^^ of the hand. 



Out of 36 subjects dissected at King's College during the Session, 34 

 have been found to present muscular abnormalities worthy of note. 

 'Four of these had also noteworthy abnormalities of some of the arteries ; 

 viz. No, 3, having 10 muscular varieties in the head and arm, had also 

 an irregularity of the third part of the subclavian, whence a common 

 trunk was given oft* for the posterior and suprascapular arteries. The
