WOUNDS OF Til 15 ARTICULATIONS.

trouble must necessarily vanish. Incipient lameness is very 
frequently established at an early period ; although it may 
not be detected till the animal is shod and put to work, when 
the unfortunate blacksmith, shoes, and all such devices, are 
summarily condemned. Thrushes are not unfrequently a 
predisposing cause of lameness ; but they are commonly 
thought lightly of, unless they give palpable evidence of in- 
convenience. Exposure to wet and filth will often produce 
them ; and they are in some measure similar to the foot-rot 
in sheep. At the same time they are more controllable and 
subservient to appropriate remedies. When the properties 
of the frog, the seat of this disorder, are considered, no sur- 
prise can exist that they should be very frequently the pre- 
disposing source of foot-lameness. A thrush may be briefly 
described as an ichorous, fetid, and corrosive discharge, pro- 
ceeding from the frogs. When this exists for any length of 
time in the foot of a young animal, it interrupts the ordinary 
secretions and development of the sensible frog ; by its dis- 
charge it promotes absorption, causing the internal part to 
assume an unhealthy degree of hardness or consistency and 
thereby affects its elasticity. The frog, it must be observed, 
is destined to prevent concussion, which in its healthy state 
it is admirably adapted for ; but if it is injured, so that its 
character and nature is changed, when the horse is put to 
w r ork soreness of the feet ensues, and often inflammation, 
which gradually increasing, the animal becomes quite lame, 
and is therefore nearly useless. As attention to the feet of 
young horses involves the necessity of handling, and such 
familiarities as will render them docile and tractable, two im- 
portant objects are secured. — Mark Lane Express . 
[There are few r writers on subjects relating to the turf or 
hunting-field, or on the breeding and general management of 
horses, who are more practical than “ Cecil.” Here, his pen 
is a powerful one ; but on the nature and treatment of diseases, 
or on the principles of animal physiology, it is less so, as the 
preceding letter fully shows.]
