fair for success ; but to be successful, it must be persevered 
in — long and patiently persevered in — ere we can expect to 
arrive at the hoped-for goal. 
Having been carried thus far with a work which has no 
stated author, owing to its being on a subject to Veteri- 
narians of first-rate import and interest, we may, before we 
close our review, perhaps be allowed to venture a conjecture 
or two about as to who its author may be. He is, we should 
opine, a cavalry officer — a ci-devant one, probably ; since he 
speaks of events over which some forty years and more have 
now rolled. He is evidently a judge of horses, and well 
acquainted with military affairs and manoeuvres. And the 
present is his second work — we think we have his first , 
though we cannot just at present lay our hands upon it — 
on a topic which, we repeat, will not fail to engross the 
fullest attention of every one engaged among or fond of 
horses ; and to him we would say, * c read the book, and reflect 
upon the matter it contains and when you have so done, 
time and leisure permitting, favour The Veterinarian with 
your opinion on matters so closely concerning us all as a 
community which lives by the well-doing and improvement 
of horseflesh.

Gentlemen, — The study of epidemics or epizootics which 
decimate both the human and animal populations, with the 
search after the causes engendering them, constitutes a vast 
problem, the solution of which is intimately bound up as 
well with the physical and moral amelioration of man, as
