muzzle, to prevent the ingestion of the agent. Carbolic acid 

 lotion (1-2 : 100) acts as a local anaesthetic, and often materially 

 lessens both licking and scratching. Lead acetate or thjMnol 

 or both (i : 100) have a similar action. Thiol 20, glycerine 50, 

 water 50, often acts as well. When the acute symptoms have 

 subsided the more stimulating agents may be employed : Creoline 

 (2 : 100) ; oil of cade i, vaseline 5 : Canada balsam i, vaseline 5; 

 zinc ointment, or lead acetate ointment. 



OTHER ACUTE ECZEMAS IN DOGS. 



Apart from eczema rubrum, the acute forms have been desig- 

 nated according to their scat and the nature of the attendant erup- 

 tion. 



Acute General Eczema. This may be often traced to various 

 causes of irritation local or general : overfeeding, over-stimulating 

 or spiced food, digestive, hepatic, or urinary disorders, irritant 

 dust or inspissated secretions on the skin, hot seasons, over exer- 

 tion, cold baths when heated, skin parasites and scratching. 



Syuiptoiiis. The whole skin, or a portion thereof is the seat of 

 pruritus, causing active scratching and on separating the hairs on 

 the affected parts there is found redness, congestion, and swelling 

 with the formation of papules or vesicles, abraded, or moist 

 surfaces, and scales or crusts. These patches are common on the 

 back, the head, cars, ricuip, (Caudal eczerna), \.\\q pa/pabrcs, the 

 lips {eczema labialis), the interdioital space (interdigital ec- 

 zema) the scrotum, or the anas. 



Sometimes the formation of crusts and the loss of hairs is to be 

 noted, sometimes the eruption of large vesicles which burst and 

 discharge a honey like fluid (impetiginous eczema), sometimes 

 blood escapes from the irritated surface and concretes in dark 

 crusts. The vesication and moist exudation is especially common 

 about the head, ears, eyelids, and rump, while bleeding is 

 especially seen around the claws and in the interdigital spaces in 

 connection with running on rougii ground, snow or stubble. The 

 impetiginous form often bears a strong resemblance to vesicles 

 caused by a burn with hot water. The treatment of these differ-
