contrary, after the third day of the fever, when they were beginning to feel a little better, they insisted on bathing. The Mohammedans and Manyema natives had learnt from the Arabs (who had not got vaccine) to inoculate with smallpox. Though on several occasions vaccine was sent to me from Europe, and packed in a dozen different ways, in no single instance could I get it to take.

This was most unfortunate, since, if I could have got but one successful case, we should have been able to vaccinate the whole population.
