that the body is specifically related to the disorder, or in other words 
represents a stage in the life-history of the specific infective agent; or, 
it may be, a culture form. 
4. Its presence, in atrophying form, in the blood of immune or 
recovered animals suggests that it assumes, after the first production of 
toxic symptoms, a passive (resting, or possibly gamete ?) stage—which 
may or may not play a part in the revival of rinderpest after passing 
through an as yet unknown cycle of development. 
5. The specific body resembles no parasite of which the life-history 
is so far known. 
Since the specific bodies can be detected in the blood of infected 
animals before clinical signs of rinderpest are observable, it is possible 
to arrive at an early diagnosis. This is of great importance in dealing 
with contacts and the early cases which usher in an outbreak. 
6. The second body described affords evidence of the existence of 
a second specific complaint which may be and probably has been in the 
past confused with true rinderpest. It would be important to determine 
if animals affected by the second complaint when they have recovered, 
are still susceptible to true rinderpest. 
7. The second body also is a new form. 
The writer offers acknowledgments to Prof Sir W. Leishman, and 
Prof Minchin, who have kindly examined his specimens, and have 
encouraged him to make this communication. The drawings to which 
these gentlemen refer, in the notes appended, are lettered a-f on PI. XIX 
and were made from fixed specimens by Miss Rhodes, at the Lister 
Institute. The remaining figures are reproduced by Miss Rhodes from 
my drawings of fresh specimens. 
Note by Colonel Sir William Leishman. 
I am much indebted to Dr Braddon for his kindness in letting me 
see some of the blood films containing the curious bodies which form the 
subject of the above communication, and I accede with pleasure to his 
request to add a word or two to his paper. 
Naturally, I can do little more than record my impression of the 
inclusions in the red corpuscles which he has found in rinderpest blood 
and in the blood of animals suffering from a disease resembling rinder¬ 
pest. These inclusions were numerous and obvious in the stained films 
which I studied, and those which I saw, as well as the coloured sketches
