W. P. Hunter's translation, 



Besides skins of this species of stag, I find, in Mr. Darwin's collection, three 

 pairs of horns, which, together with a pair belonging to one of the skins, consti- 

 tute a sufficiently complete series to illustrate the different forms which these 

 appendages assume, as the animal increases in size. 



Scale of twelve Inchei 



The above four sketches, which are all drawn to the same scale, will help to 

 convey a clear idea of the forms, and relative proportions, of these horns. 



The most simple horn (fig. 1 .) consists of a beam, eight and a half inches 

 long, which is slightly arched outwards and considerably compressed about two 

 and a half inches from the apex. At one inch from the base there is a small brow 

 antler which projects forwards and upwards. 



In the next horn, (fig. 2.) there is the same small brow antler, but there is a 

 single small snag, about equal in size to the brow antler, which is directed back- 



* Figures 47 and 48 of M. Cuvier s work represent horns so unlike either of those brought over by Mr. 

 Darwin, that I cannot help suspecting they belong to some other species of stag.
