 and condition through the summer, and grew a good (though by no 

 means large) pair of horns. 



"During the night of October 18-1 9th last, these horns were shed ;

" Mr. Smit's drawings that I now exhibit were made on the spot, 

 under my supervision, the day after the shedding (October 20). 



" Fig. 1 shows the general form and size of the new horns. From it

 going on here at a rapid pace. The top part, about one inch long, is 

 smoother and blacker, though nearly white at the tip. It is nearly 

 glabrous, with only a very few small hairs, and has the appearance and 

 touch of ordinary horn. It is separated from the basal ' pedicel ' part by
