136 LETTERS TO MR. GIBB. [CHAP. xv. 



in the structure of the feet which may prove of importance 

 practically. However it may have been known, so I have 

 written to-day to our great English authority, Mr. Me'ade, 

 to ask him what he thinks about it and will write you again.

 at all to making a more useful figure than that by Dr. 

 Taschenberg, which tells little. Mine is after the figure by

 " Veterinary Record." I have identified them with quite
