V. Ringworm. 

 This is a fungous, vegetable parasitic growth, scientifically known as 

 tricophy ton tonsurans . It is contagious, and attacks all classes of ani- 

 mals, yet sometimes arises spontaneously from poverty and filth. It 



manifests itself by a round 

 ])ald spot, scaly and elevated 

 inside the ring, which is red 

 and inflamed. It begins in a 

 small pimple-like sore, which 

 spreads very fast, increasing 

 in size from day to day, and 

 new sores forming on other 

 parts of the body. The ring 

 is surrounded by a row of broken, bristly hairs, which split, and become 

 filled with spore* of the fungus ; and as fast as one row of hairs is dis- 

 posed of another row is attacked. 



Ringworm is, at first, simply a disfigurement, but it should, on no 

 account, be neglected. If allowed to run on, it becomes very trouble- 

 some. The scurfy skin of ringworm is easy of recognition, the particles 

 of scurf coming off in little flakes or scales, which have been aptly com- 

 pared to the coarser, husky portions of bran.
