ing- few isolated nodules. While crnsts form again on some of 

 the bald places, in others only a more or less copious desquama- 

 tion occurs, hence the process either remains local, or numerous 

 patches of herpes arise, especially when the itching, which al- 

 ways accompanies the process, is intense. If the process ex- 

 tends in this manner, single patches coalesce into irregular sur- 



A special form of herpes tonsurans crustaceus which hith- 

 ertohas only been noticed in the dog, manifests itself by the for- 

 mation of nodular or glandiform semispherical or half-egg 

 shaped elevations on the scalp and especially on the cheeks, 1 

 to 2 cm. thick, which contrast sharply against the healthy skin 

 (Fig. 133) ; they are reddish brown in color, rather firm as well 

 as sensitive, while on their surface few hairs or hair stumps 

 stand out. After removing the deposits one sees the widened

 hairs are pulled out or on pressure on the swelling. The com- 

 plaint is protracted, lasting several months, and after healing 

 the patches remain completely bald (Schindelka). 



Herpes tonsurans maculosus et vesicidosus not infrequently 

 attacks the parts of the skin which are only sparsely covered 

 with hair and manifests itself by similar symptoms to those de- 

 scribed in other species of animals (see Fig. 134). By coales- 

 cence of neighboring patches map-like figures may be formed. 



Finally a form of the disease described as "shearing" 

 herpes (microsporosis) may be observed very rarely, although 

 according to Sabouraud, Suis & Suffran, it is quite frequent in 

 the surroundings of Toulouse. Bodin & Almy claim that it is
