230 THE CONTAGIOUS TYPHUS 



lively, neither costive nor scouring, and chewing their 

 cud, then the operation may be safely undertaken, and 

 henceforth they must be confined to the barn. 



" Since there is observed to follow the greatest flow of 

 the contagious and putrid particles separated from the 

 blood, wherever the infectious matter makes an impres- 

 sion at first, particular care must be taken not to inocu- 

 late near such vital parts as the heart and lungs, nor 

 near the womb, if a cow with calf be inoculated j for, 

 though rowels are properly applied in the dewlaps, to 

 draw off the pestilential humour from the breast, and in 

 other cases beasts are frequently rowelled in the flanks, 

 yet in this operation, as matter is inserted by these 

 channels into the neighbouring vessels, those vital parts, 

 or the womb, might become the chief seat of the disease, 

 and the event prove fatal. 



" To prevent such accidents, human beings have been 

 inoculated on the arms and legs, and now-a-days the arms 

 are found sufficient. I would recommend that the cattle 

 should be inoculated about the middle of the shoulders or 

 buttocks, on both sides, to have the benefit of two drains. 

 The skin is to be cut lengthways two inches, deep enough 

 for the blood to start, but not to bleed much. In this in- 

 cision is to be put a dossil or pledget of tow, dipped in the 

 matter of a boil full ripe, opened in the back of a young 

 calf recovering from the distemper. It may not be amiss 

 to stitch up the wound, to keep the tow in, and let it re- 

 main forty-eight hours. Then the stitches are to be cut, 

 the tow taken out, and the wound dressed with yellow 

 basilicon ointment, or one made with turpentine and yolk 

 of egg, spread on pledgets of tow. These dressings are to 

 be continued during the whole illness, and till after the 

 recovery of the beast, to promote the discharge ; and then 

 the wound may be healed with the cerate of lapis calanii- 

 naris, or any other.
