TROPICAL MEDICINE AND HYGIENE 



FIG. 40. Chart V, 1911. Tartar emetic given intravenously every fifth day, but 

 no atoxyl, for some time seemed to be a success ; as the temperature, except for the 

 rises which followed the injections, was normal, and no trypanosomes were found. 

 Ultimately the temperature began to rise on the fifth, and trypanosomes were 

 sometimes found on that day. 



FIG. 41. Chart VI, 1911. Later condition. Under atoxyl the temperature 

 remains about normal for eight to twelve days and no trypanosomes are found. Then 

 there is a rise of temperature, and, as a rule, trypanosomes can be found. An intra- 

 venous injection of tartar emetic is followed by a severe reaction, indicated by the 

 dotted line in the temperature chart, and the temperature then falls and trypano- 

 somes cannot be found for another period. The use of atoxyl now seems to 

 have lengthened the period of well-being from four or five to eight to twelve days.
