254 MESSRS. MIVART AND MURIE ON THE [Feb. 28, 
fleshy bellies, each giving off two slender and perforated tendons 
which go to the fourth and fifth digits respectively (fig. 6, F. b. d). 
We did not observe an accessorius. 
The small muscles of both hand and foot, which belong to the 
first and fifth digits respectively, we found to exist as mentioned by 
our authors: and with regard to the interossei of the hand and foot, 
these are represeuted (as they appeared to us) in the woodcuts 
(figs. 4 & 7); but we refrain from giving a detailed description of 
them, as a fresh dissection would be required to confirm and satisfy 
ourselves as to the perfect accuracy of our observations upon them. 
Enlarged view of the plantar surface of the foot, to show the small muscles of 
the hallux and fifth digits, the interossei, and the lumbricales attached to the 
flexor tendons. 
On carefully comparing the brain of our specimen with the de- 
scription of Professors Van der Kolk and Vrolik, and likewise with 
the careful and minute account given by Mr. W. H. Flower’, of the 
brain of Nycticebus javanicus, we found it to agree completely with 
the statements of the latter author, except that the posterior parts 
of the Sylvian fissures converged instead of being parallel. 
A slight difference existed in form and dimensions; but these, 
doubtless, were due to its having been previously preserved in 
alcohol. 
The viscera agree with Professors Van der Kolk and W. Vrolik’s 
account of them. It may be worth while at the same time to men-
