176 OPEBATIONS ON THE SKIN AND CELLULAR TISSUE. 



author of the first report of its results. The first cautery used 

 by Abadie resembled the one shown in Fig. 206. In using it, 

 the animal is generally secured in the standing position. It is 

 applied at a Hght red heat and made to penetrate through all the 

 tissues down to the subcutaneous cellular structure, and even 

 through the synovial sheaths. Leblanc's advice is to make the 

 puncture by passing the iron three or four times in succession in 

 the same spot, but Abadie completes it at a single stroke. This 

 firing is followed by severe inflammation of the parts, great pain, 

 swelling, abundant serous secretion, and the escape of synovial 

 fluid. It has, therefore, powerful revulsive eflfects, which, how- 

 ever, leave scarcely any marks, provided only the finest parts of 

 the cautery have penetrated the tissues. Otherwise extensive and 

 fatal suppurative arthritis may be looked for. This cauterization 

 is indicated in cases of exostosis, tendinous swellings, articular and 

 tendinous synovial dilatations, splints, ringbones, spavin, side- 

 bones, thick tendons, articular and tendinous windgalls, thorough 

 pins, blood spavins, etc. 



In the true needle cauterization or ignipuncture, the form of 

 the cautery is changed, but in all other respects there is no 

 difference. 



The forms of the needle instruments are numerous, and of 

 course each one claims some special merit. The cautery of 

 Bianchi and that of Foucher were first used, and these were fol- 

 lowed by the instruments in which the point or needle of platinum 

 could be changed. There were others of more compUcated make, 

 as those of Bourguet, SaUes, Lagarrigue, Vasselin and others, or
