 water; 1 part of carbolic acid, 10 of alcohol, 10 of water; 4 parts 

 of creolin, 100 of water; 1 part of ichthyol, 10 of glycerin, 30 

 of water ; 10 parts of nitrate of silver, 100 of water (Friedberger). 

 In very obstinate cases we may also use laxatives or purgatives 

 (aloe, jalap, salines, etc.), also the internal administration of arsenic 

 in the form of Fowler's or Donovan's solution. 



Urticaria. 



(Nettlerash.) 



Nettlerash was only seen in three cases by the author. The 

 subjects were all small, well-fed, middle-aged dogs, which were 

 covered over the entire body with circumspect, flat, beet-like eleva- 

 tions, about one and one-half inch in diameter, only slightly red, 

 and which had originated spontaneously. They were rapidly 

 lessened by the administration of purgatives. 



Eczema. 

 {Red Mange.) 



By this we mean an inflammatory condition of the cutaneous 

 membrane indicated by redness, swelling, nodules, pustules, vesi- 

 cles, scabs, and crusts, which are generally accompanied with 

 more or less itching. In the flrst stages development of a hyper- 

 ssmia is seen, thus reddening the skin superficially, and accom- 

 panied by a serous exudation. If the inflammatory irritation 

 stops, or if proper therapeutic measures are taken, recovery may 

 occur at once, and we have a more or less prolonged desqua- 

 mation of the epidermis. In the majority of cases, however, the 

 irritation increases and we may have the formation of numerous 

 pale red, tough, itching nodules, accompanied by serous swellings 

 and slight cellular infiltration of the papillae, but generally it is con- 

 nected with the cutaneous follicles. This condition may become 

 retrogressive; the nodules become depressed, forming scabs. In 

 other cases the serous exudation increases constantly inside the 

 papule, and, as a consequence, we have a rising of the horny layer 

 in these locations ; or, in other words, numerous vesicles are formed 

 (eczema vesiculosum). If the horny covering is strong enough
