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.
