In purpura, also, the diet should at first be moist and nutritious, The 
“medicinal treatment of this dangerous malady requires great professional 
skill in order to bring it to a successful termination, The swellings should 
be fomented, but not punctured. The sores should be kept very clean and 
dressed with some antiseptic solution, as carbolic acid (one part in forty of 
water). During recovery tonics are required. ; 
GENERAL DISEASES DUE TO ERRORS IN DIETING 
AND MANAGEMENT.

‘UNDER this heading we propose to treat of those general diseases of the 
horse which are in most cases due to dietetic errors, or to some irregularities 
in the management. Of the diseases of special parts, such as colic, due 
to similar causes, we shall speak when we have to deal with local diseases. 
The first of the general diseases which we here wish to bring before 
*the notice of our readers is one commonly known in Lincolnshire as 
“weed,” “the humour,” “farcied leg” (though it has no relationship with 
farcy), sometimes spoken of as the “Monday morning disease,” and in 
scientific language termed “lymphangitis.” 
Of this malady it is very essential that all who keep draught horses 
-especially should have some clear knowledge ; for, with due precautions 
and careful management, it“is, in common with some other general diseases of 
‘the horse of which we now speak, largely preventible, and very amenable to 
judicious treatment. Weed is not at.all an uncommon disease of the horse ; 
but we should mention, before entering into details, that it is a special 
‘inflammatory malady, and must not be confounded with other ‘forms of 
-disorder such as humour or farcy. 
It is a general affection of the constitution attended by inflammation, 
beginning in the glands at the upper part of one of the limbs, in most cases 
a hind one. The leg becomes swollen, and when pressed upon by the 
finger “pits.” In some cases both hind limbs are affected, and in rare 
instances a fore limb is the seat of the disease. The commonest situation 
however is the left hind leg. Regarding the nature and causes of weed, we 
may say that it is a general disorder of function, especially associated with 
impaired digestion and disordered assimilation of the food. It is 
especially a disease of the heavy draught horse of sluggish lymphatic 
temperament, and is particularly common among certain breeds of agricultural 
horses. 
One attack renders an animal more subject to a second, and in many 
cases one seizure succeeds another periodically, until the limb becomes
