therefore, considered justifiable to regard the test as specific, and to conclude 

 in case of a positive reaction not only that the disease is present but that the 

 lesion is in an active condition. A negative result, as in the Wassermann test, 

 is considei-ed significant though inconclusive.

Contribution to the study of ulcerous lymphangitis (Rev. G6n. M4d. V6t., 

 28 {1919), Xo. 329, pp. 233-^43). — This is the report of a series of studies on 

 tlie nature of ulcerous lymphangitis and its mode of transmission, therapy, and 

 diagnosis. Evidence is furnished that the bacillus of Preisz-Nocard is the 

 specific cause of the disease, and that it is possible to reproduce it experi- 

 mentally by local inoculation of very small doses of a young culture of the 

 organism, associated preferably with an inert substance such as powered char- 

 coal. The true symptoms of the disease do not appear until about a month 

 after the virulent injection. 



The therapeutic agents studied included toxins such as mallein, tuberculin, 

 rivoltin, etc., specific vaccines, chemical substances, serums, and surgical 

 methods. In no case were entirely satisfactory results obtained. The various 

 methods of treatment apparently hastened the cure of light attacks, but had 

 little effect on extended lesions. 



While the injection into the conjunctival tissue of a glycerin extract of a 

 pure cultui'e of the bacilli of Preisz-Nocard produced a reaction in animals 

 afflicted with the disease, such a reaction is not considered specific as an edema 

 was also produced at the point of inoculation in healthy animals.
