Abstract
Trypanosoma brucei in quantities sufficient for antigenic analysis was obtained by harvesting the blood of rats on the third day of infection by the protozoon, when the fulminating parasitæmia is at its height. The trypanosomes were separated from the blood by centrifugation and the resulting mash was preserved by freeze drying. Several batches made in this way were pooled.
