disposition of pus to advance harmlessly toward the surface and 

 escape; and, finally, by a low prostrating type of fever, with ele- 

 vated temperature of the body, coated tongue, excited breathing and 

 loss of appetite. The pus Avhen escaping through a lancet wound is 

 grayish, brownish, or reddish, with a heavy or fetid odor, and inter- 

 mixed with shreds of broken-down tissues. The most destructive 

 form, however, is that in which pus is deficient, and gangrene and 

 sloughing more speedy and extensive. 



Treatment resolves itself mainly into the elimination from the svs- 

 tem of the poisonous products of the bacteria by laxatives and diu- 



abo^ e all those of the nature of antiferments, and the local application 

 of astringent and antiseptic agents. Internal treatment may consist 

 m 4 drams tincture of muriate of iron, and one-half dram muriate of 

 ammonia or chlorate of potash, given in a pint of water every two 

 houi-s. lo this may be added, liberally, whisky or brandy when the 

 pro.stration is very marked. Locally a strong solution of iron, alum 

 or of sulphate of iron and laudanum may be used. Or the affected 

 part may be painted with tincture of muriate of iron or with iodized 

 phenol. In mild cases a lotion of 4 drams sugar of lead and 2 ounces 

 audanum m a quart of water may be applied. It is desirable to avoid 

 the formation of wounds and the consequent septic action, yet when 

 pus has formed, and is felt by fluctuation under the finger to be 

 approaching the surface, it should be freely opened with a clean 

 sharp lancet, and the wound thereafter disinfected daily with carbolic 

 acid 1 part to water 10 parts, with a saturated solution of hvposul- 

 phite of soda, or with powders of iodoform or salol

CALLOSITIES. 



These are simple thickening and induration of the cuticle by rea- 

 son of continued pressure, notably in lying down on a hard surface 

 I>eing devoid of hair, they cause blemishes, hence smooth floods and 

 good bedding should be secured as preventives.
