PATHOLOGICAL ANATOMY, 
PARASITIC 
NATURE OF MELANOSIS AND OF 
SOME MELANOTIC 
r 
TUMORS. 
By L. Bard. 
Clinical facts can be cited in favor of this parasitic origin—a 
primitive focus externally, at the extremity of a leg—localization 
,nd prolonged stationary condition—very rapid generalization. 
From the point of view of the anatomo-pathological student, 
aelanotic tumors may be divided into three groups. These are, 
irstly, cystic masses, where the tissues have all disappeared; sec- 
ndly, simple circumscribed melanotic masses in the form of 
amors; and thirdly, tumors of small size, with small granular 
aelanotic centres.

This last variety is the type of the second growth, of recent 
ormation, constituting the first steps towards melanotic develop- 
aent. The progressive advance of these alterations, the presence 
f fragmentary granulations around the centres of propagation, 
aeir accumulation, and continuous increase, as the lesion, during 
iS progress through the economy shows itself—these anatomical 
I lets suggest to the author the idea that the melanotic granules 
fight be the patliologenic parasitic organism. It may not be a 
licrobe, but one of those sporula organisms, the fungi of the 
dinomycosis kind, which would be the propagating agent of the 
isease .—Revue des Sciences Medicates . 
PON A MICROBE WHOSE PRESENCE SEEMED TO RELATE TO 
RABID YIRULENCY. 
By H. Fol. 
By employing the method of Ehrlich and Weigert for harden- 
g and coloring the sections, and using sections of one two-hun- 
•edth millimetres thickness, Mr. Fol has succeeded in finding in 
e marrow of rabid animals, elements which are not found in 
I e healthy marrow. These are groups of small globules, resem- 
ing microccocci, lodged in the nevroglia, or in cavities having
