Scarlatina (Scarlet Fever). 



Scarlet fever, or scarletina, as it occurs among horses in the 

 United States, is a febrile disease of a very prostrating character j 

 yet it is not considered by the author a contagious malady. L 

 has only lately, however, been recognized in this country as a dla* 

 tinct equine disease, and, being of rather rare occurrence, we know 

 but little about it. The cases that have come under the author's 

 treatment were unattended by ulceration of the throat, and this 

 may account for the non-contagion ; for, in the human subject, 

 when ulceration of the throat takes place, the case becomes ma- 

 lignant. 



Watson says : " The malignant sore throat may be caught 

 from a j)atient who has mild scarlet fever ; and mild scarlet fever 

 may, in like manner, be contracted from one who is suifering 

 under the malignant sore throat. The two forms graduate insen- 

 sibly, in different cases, toward each other; and it would be im- 

 possible, even if it were desirable, to draw any strict line of 

 separation between them. Many would say, and probably with 

 truth, that the difference was this: in the one form, tLe poison cf 

 the disorder is seeking its vent, principally, by the throat; in the 

 other, by the skin." It appears, therefore, that in the human 

 subject the disease is capable of being communicated at any stage. 



The cases that have come under the author's notice since he first 

 recognized the malady have all been of a mild form ; that is t« 

 say, non-malignant. The limbs, sheath, and pectoral regions were 

 excessively dropsical ; the skin wais the seat cf rash or minute *Jf •
