172 ON THE INFLAMMATORY FEVER OF CATTLE. 
embrocations is composed of equal parts of turpentine, hartshorn, 
and camphorated spirit. 
When the stage of convalescence commences, slight tonics may 
be allowed (the gentian, ginger, and nitre are the best); but no 
mineral tonic should be administered. 1 have seen two or three 
cases in which irreparable mischief has been done by the too 
early and plentiful use of a mineral tonic. 
Bran mashes, or malt mashes, in small quantities, may be 
given, and the animal turned into a field where the grass has al¬ 
ready been cropped pretty close. In general cases, however, I j 
believe that the most scientific and the most successful practice 
is, after having subdued the disease, to leave nature to her own 
energies, slowly and successfully to resume her wonted functions. 
A seton or a rowel might be retained with advantage for three or 
four weeks. 
Preventive treatment. —This is a very important branch 
of our art. When inflammatory fever begins to appear among 
the cattle, the farmer may be assured that he is making more 
haste than good speed ; and that the disease of one indicates the 
danger of others. All who have been exposed to the same pre¬ 
disposing causes should lose six or eight pounds of blood ; have 
a good dose of Epsom salts, and be turned into a field of short 
and inferior keep, what John Lawrence appropriately calls a di¬ 
gesting place. By the adoption of these means, and these only, . 
I completely stopped the farther progress of the disease in the 
dairy to which I just now referred. Any considerable degree of 
heaving, inflammation of the eyes, heat-bumps on the back, 
rubbing, should be regarded as a warning of the possible or pro¬ 
bable approach of mischief. The loss of blood, and the action of 
a purgative, and a repose of two or three days, and after that of a 
few hours every day, in the digesting place, would not retard the 
progress of fattening, but rather the contrary; while the vascular 
system would be relieved, and dangerous congestion prevented.
