Mr. Ogilby remarked, with veference to this subject, that he had 

 had opportunities of observing, at Ihe Surrey Zoological Gardens, a 

 female of the Indian Antelope, in which, when he first saw her, the

 universal, that in intertropical animals the lacrymal sinus is larger 

 than in more northern species, and in those whose range is limited to 

 mountainous districts. 



He also described the lacrymal sinus of a species of Gazelle, vvhich 

 he had observed after death : it consisted of a gland furnished vvith six 

 excretory ducts placed nearly in a circle, and vvith one centrai duot ; 

 from the orifices of these ducts, when sąueezed, there issued out 

 strings of a dense ceruminous matter. 



Mr. Bennett stated in conclusion, that since making his observa-
