may be applied cold, whereas in the cold weather hot applica- 

 tions are often preferable. Aruch claims excellent results from 

 covering the engorged head with a woolen cloth and irrigating it 

 with cold water. 



The question of drainage of the worst cutaneous swellings by 

 scarification, has been variously dealt with, Dieckerhoff advocating 

 deep incisions, while Friedberger and others forbid them as en- 

 creasing the tendency to necrotic infection and sloughing. . In 

 the slighter cases it can well be omitted, but in extensive swell- 

 ings the disintegrating and debilitating action on the tissues is so 

 great as to well warrant its prevention by incisions and drainage 

 It is well to first give the surface a soapy wash, then apply a mer- 

 curic chloride or carbolic acid lotion and lance it in the prominent 

 and tense portions. As ar^urther precaution against septic in- 

 fection it may then be covered by cotton soaked in one of the 

 above lotions and covered with a bandage. For swellings be- 

 neath the abdomen or chest this may be held in place by loose 

 circingles. Scarifying becomes imperative in case of paraphy- 

 mosis arresting the flow of urine. Deep fissures and sores fol- 

 lowing sloughing may be treated with mercuric chloride solution, 

 (1:1000), creolin or phenic acid (2:100), iodoform, dermatin, 

 naphthalin orsalol. 



Disinfection of the nasal passages has been attempted by per- 

 vading the air with carbolic acid, creolin, cresyl, lysol, or naph- 

 thalin, by hanging saturated cloths in the stall, or spreading them 

 on the floor. Perhaps a better method is to flush out the nose, 

 by injecting each chamber in turn with a piece of rubber tubing, 

 one end of which is introduced into the nose, and the other 

 raised four feet and furnished with a funnel. The injection may 

 be I dram creolin to 2 quarts water, or carbolic acid or alum may 

 be substituted or alternated. 



The swelling of the nostrils may be so great that it becomes 

 requisite to hold them open mechanically. The suture of the 

 two together, across above the nose has been practised, or a 

 tube of light wood or aluminum can be inserted in each nostril. 



Injection of the trachea and bronchia with a solution of iodine i 

 part, potassium iodide 5 parts, and water 100 or 200 parts, was 

 advocated by Dieckerhoff and met with a fair measure of success 

 in mild cases. In some cases, however, granular tracheitis and
