ERUPTION CATTLE PLAGUE.

a 



Section through cuticle and cutis in the seat of the 

 eruption, cattle plague, showing at a a papilla, the cuticle 

 over which is still in a healthy state, while that above 

 the papillae at 6 is undergoing disintegration caused by 

 the growth and multiplication of contagious bioplasm 

 among the cuticular cells, as shown by the dark patches. 



Outline plan showing how the contagious bioplasm 

 may pass from the capillaries and reach that part of 

 the cuticle where the layers of cells are parallel, a. 

 whence it spreads horizontally in various directions, 

 and thus strips off the superficial layers of the cuticle
