in a line with the course of the vein, with one smart tap of 

 the blood-stick the skin and coats of the vein are punctured, 

 and the blood will flow. When sufficient has been abstracted, 

 the edges of the wound should be carefully taken together, 

 and hairs and clot carefully wiped away; a small pin is passed 

 through them, and a little tow wound round it, and the point 

 of the pin cut ofi'. The head should be tied up for a few 

 hours to prevent him rubbing the pin off. 



THE EOWEL. 



Eowels are used as counter-irritants in treating deep-seated 

 inflammations, and " whenever any morbid disease is to be

 and thumb, and a cut is made in the skin with the rowelling 

 scissors, and with the hook- on the handle of the scissors it 

 is separated frcrm its cellular connexions for about two inches, 

 and a dossil of tow, or a circular piece of leather, with a hole 

 in it, previously dipped in digestive ointment, is inserted, 

 which must be cleaned and moved every day. A discharge 

 is soon set up, which has a tendency to remove any deep- 

 seated morbid action. 



SETONS. 



Setons are similar in their action to rowels, and are used 

 for much the same purposes. They are usually made of broad 

 white tape. In inserting a seton, the skin is cut with the 

 rowelling scissors as above ; a seton needle, which should be ' 

 large and well polished, is passed in and pushed under the 

 skin as far as is necessary; another cut is then made in the 

 skin, through which it is passed out ; the needle in its course 

 should separate the skin on each side from its cellular at-
