* T found the following results from the dissection of a fine specimen of the 

 common Llama:—

In this animal the cross section of the tendons of the toes of the hind foot 

 exceeds that of the tendons of the fore foot in the proportion of 444 to 41 1.

The relative strengths of the tendons of the toes are very similar to thos< 

 the Negro Monkey (p. 95), and very unlike those of the Macaque (p. 94). The 

 fl. hall. long, flexes the first, second, third, and fourth toes ; while the fl. dig. 

 long, flexes the first, second, third, fourth, and fifth. This arrangement resem- 

 bles that of the flexor tendons of the Capuchin and Negro monkeys, in this re- 

 spect, that the entire flexion of the fifth toe devolves on the fl. dig. longus.
