blood of a child 3 years of age, a native of Gambia. The child showed 
no symptoms of disease. 
Eight additional cases of human trypanosamiasis . — In the British 
Medical Journal for February 7, 1903, there is a “preliminary account 
of the investigations of the Liverpool expedition to Senegambia,” by 
Dutton, Annett, and Todd. They found trypanosomes in the blood 
of a white trader who had been twenty years in Gambia. The highest 
number found in a fresh preparation was seven. The patient had 
lost 45 pounds within the past year, complained of weakness and 
breathlessness, and had slight fever at times. The spleen was 
enlarged and there was pitting of the ankles. Four other cases of 
infection of natives were found. 
Three more cases of human trypanosomiasis are reported in the 
British Medical Journal for March 28, 1903, by Dr. Patrick Manson. 
They came from the European community on the Kongo, as did also 
Dr. Manson’s first case. A blotchy erjThema and attacks of fever 
characterized these cases. 
Tlie finding of trypanosomes in man, associated with a well-defined 
group of signs and symptoms, is no small contribution to the disen- 
tanglement of the diseases of the Tropics. These cases will lead to 
the recognition of others, perhaps, in the tropical parts of our own 
continent or of Asia. The disease has been found in MTest Africa, 
and with this new fact in parasitology before us its geographical dis- 
tribution may be found to have a much vider range. On account of 
the interest which surra claims in the Philippines and on account of 
the recognition within the past year of trypanosomes in man, and 
since the process of development and conveyance of these blood para- 
sites have heretofore been little investigated in this country, we have 
undertaken this study. 
AVe wish to call attention to the autoagglutination, transmission by 
feeding, transmission by intrastomachal injection, and to the staining. 
I am glad to thank the director of the laboratory. Dr. M. J. Rose- 
nau, for his interest in outlining the work. 
I am indebted to Dr. John F. Anderson, the assistant director, for 
valuable suggestions, especially in the staining of the parasites. 
I also desire to express my thanks to Dr. H. B. Parker for making 
the microphotographs.
