Preliminary note upon a trypanosome occurring in the blood of man.

Dutton was the first to recognize human trypanosomiasis. He saw Forde’s patient (see No. 5274) and named the trypanosome T. gambiense. Sleeping sickness itself has been referred to as “Dutton’s disease”. The first announcement was in the form of a telegram to Ronald Ross, published in Brit. med. J., 1902, 1, 42.
