which is also common and is transitory between the asthenic 

 hollow ulcer and the polypoid ulcer, is the cratcr-likc 2ilccr, 

 which is more or less prominent over the skin, and is generally 

 covered with red brown or orange brown scabs ; on removing 

 the latter we find, at the centre of the ulcer, a small opening 

 of bean-size surrounded by a salient border. The ulcer looks 

 reddish yellow, and the central hole is often blocked up witli 

 glutinous matter consisting of fibrine coagulum mixed with red 

 and white corpuscles and the microbes. By mechanical injury, 

 such as biting, rubbing, &c., there may appear an extend- 

 ed ulceration, necrosis, or a diffuse thickening of the skin 

 and subcutis, resuhing either in an extensive destruction 

 of tissue or clepJiantiasis. In such cases different septic and 

 pyogenic microbes, which have access to the wound, ac- 

 celerate the progress of the disease. When the ulcer heals 

 it leaves in the skin a funnel-shaped cicatrix destitute of 

 hair. The following table shows how special parts of the body 

 are attacked ; the data are tlie reduction of the reports"' of

It will be seen that the anterior part of the body is more affected 

 than the posterior. The percentage of nasal affection is too 

 low ; this is perhaps due, in the first place, to the fact that
