22 “ EVIDENCE IN HORSE CASES.” 
[Our thanks are due to Mr. Blakeway for affording us the 
opportunity of examining two of the navicular bones— 
one belonging to the fore, the other to the hind limb —of the 
animal to which the above communication refers. In each 
of these, caries had taken place to a considerable extent, and 
the diffused inflammatory action, necessarily accompanying 
this condition of the bones, had, in one of them especially, 
led to ossification of the ligaments. The remote cause 
of the inflammation of the bone tissue which resulted 
in caries must, we think, be regarded as constitutional, but 
whether hereditary or not we have not sufficient evidence to 
determine. Doubtless in many instances, hereditary predis¬ 
position or constitutional diathesis plays an important part 
in the production of disease of bone tissue, as of other 
structures of the body, and as such will account in part for 
the great prevalence of splints, spavins, and allied osseous 
deposits, which we daily meet with in the examination of 
horses. Notwithstanding these causes and the application 
of others, which are the immediate or exciting ones in the 
production of navicular disease, the existence of the affection 
in all four feet at the same time is exceedingly rare, and we 
are glad to be enabled to place such a case on record.— Eds.] 
“ EVIDENCE IN HORSE CASES ” 
To the Editors of the i Veterinarian .’ 
Gentlemen, 
The attention of my client, Mr. T. A. Dollar, has 
been called to statements appearing in the December number 
of the Veterinarian , page 794, relative to the case of Harris 
v. Jacobson, under the heading “Evidence in Horse Cases.” 
The statements are both erroneous and unjustifiable, and are 
calculated to do great injury to the professional status of my 
client. 
The clause of which Mr. Dollar complains especially is as 
follows :—“ On his” (i. e. the plaintiff’s) “ behalf was called 
“ Mr. T. A. Dollar, of New Bond Street, who described 
“ himself as veterinary surgeon to the Prince of Wales, but 
“ afterwards admitted that he was not a member of any 
“ college.” 
Mr. Dollar did not describe himself as “veterinary
