    The following table indicates the results of examinations of cover-slip preparations of finger blood taken from four hundred and sixty-five natives at Leopoldville. The results of similar examinations, made in the region lying between Stanley Pool and the sea, are appended in order to present a concise idea of the prevalence of human trypanosomiasis in the Congo :— Number of Cases Number with | with Trypano- Class of Native Number examined) Trypanosomes in| somes previously Finger Blood |diagnosed as sleep- ing sickness Healthy labourers, prisoners, women, and children, all resident for varying periods in or near Leopoldville, but many of whom are natives of distant parts of the Free State te i 255 6 fo) Outpatients visiting the clinic of the State Doctor at Leopoldville and chosen for examination because of their miserable appearance ... se 53 3 2 Patients admitted by State Doctor to native hospital nae ofa ee Teo 45 34 Total for Tecnica, ae er mt es Brera es 36 .

In the Congo we have also seen examples of the mild Gambian type, but the majority of our cases have shown marked symptoms of illness. From a close study of these cases it becomes evident that there is no well-defined line of demarcation between these two forms of the disease, though for descriptive purposes we propose to consider them under three main headings, A, B, and C :— Type A. Cases with no definite symptoms of illness. » B. Cases with few symptoms. i ihoteeetatalcases showing well-marked symptoms, the most notable being fever, lassitude, weakness, and wasting. 1.
