SOME PECULIAR AND PROBABLY SPECIFIC 
BODIES IN THE ERYTHROCYTES IN RINDER¬ 
PEST AND ANOTHER ALLIED DISEASE. 
By W. LEONARD BRADDON, B.S., F.R.C.S., 
With some observations on the specimens by Col. Sir 
Wm. Leishman, F.R.S., K.H.P., R.A.M.C., and Professor 
E. A. Minchin, Ph.D., F.R.S. 
(With Plate XIX.) 
I. Rinderpest. 
The virus of rinderpest is present in the blood and all the body-fluids 
during the febrile period. In the blood it is so plentiful that the 
inoculation of a single drop of a 1 in 10,000 dilution is said to be 
sufficient to infect a calf. According to Nicolle and Adil Bey^ 
the causal agent is filterable, and therefore is supposed to be ultra- 
microscopic. Direct examination of fresh specimens reveals nothing 
parasitic, nor has anything of the kind been shown by various methods 
of staining of dried films. 
But the writer, who had extensive opportunities for study in 
connection with an experimental investigation into the production of 
a protective serum for buffaloes, conducted for the Federated Malay 
States Government in 1901, found that by the application of a special 
method which he was in the habit of using in blood-studies, there could 
be constantly defined in the blood of rinderpest-affected animals certain 
bodies, not found in controls. The description and illustration of these 
appearances form the subject of this paper, to which Sir W. Leishman 
and Prof. Minchin have added the value of their remarks upon the 
specimens which they have been good enough to examine.
