extent in the United States. The author has seen two cases, 

 occurring in subjects of the scrofulous diathesis, which has led 

 him to suppose that the disease is of a scrofulous character : at 

 any rate, it sometimes depends on internal causes ; and therefore, 

 in addition to the local remedies, some sort of medicine of an 

 alterative character must be given. See Alteratives. 



The term malanders is applied to the disease when the fore 

 legs are affected, and salanders when it is located in the hind 

 ones. As both are supposed to proceed from the same cause, 

 the local treatment consists in washing the parts twice a day 

 with an alkaline wash — lime water — or saleratus ; and after 

 the part or parts are wiped dry, the following application must 

 be used : —

POULTRY LOUSINESS IN HORSES. 



Poultry lousiness, one of the evils of domestication, has prob- 

 ably never occupied much of the attention of horse owners in this 

 country ; yet it is important that such should be made acquainted 

 with the facts in relation to it, because a knowledge of them may 

 explain the origin of many cutaneous diseases — attended with 

 loss of hair — that seem to have a spontaneous origin, and at the 

 same time resist the ordinary treatment. It is very necessary 



for a pimple to be thrown out spontaneously on the surface of the body without 

 some previous lesion, however slight, either of the solids or the circulating 

 fluids of the system ; else we should have an effect without a cause. In like 

 manner, every cutaneous disease, wbethcr arising spontaneously, like lepra or 

 herpes, or whether resulting from contagion, as scabies or porrigo, either 

 originally or ultimately involves the constitution, more or less obviously, in the 

 changes which are taking place in the capillary system. As the brain takes 

 cognizance of every disturbance in the extremities of the nerves, so the heart 

 receives and reflects an impression when the minute vessels, however distant 

 from the centre of circulation, become congested or inflamed. In fact, a sym- 

 pathy exists throughout both systems, and in all parts of the frame ; so that 

 every part of the body suffers with every member, and each member with the 

 whole body — the local disease, when communicated from without, becoming 

 the cause of the constitutional disturbance, and vice versa ; the general 

 cachexy, when it exists primarily, becoming, in its turn, the cause of the local 

 affection."
