230 REPORT OF THE HARVARD AFRICAN EXPEDITION 
sudden death. During 1927 six fatal cases were recorded among the large 
number of patients injected with tartar emetic. Khalil states, however, that 
it is certain that this official number of deaths is very much below what is 
expected, and that there is no doubt that many cases are concealed by their 
relatives in order that they may avoid postmortem examination and legal in- 
vestigations. 
In connection with the treatment of schistosomiasis in Africa, Dr. Shattuck * 
has recommended the use of the less toxic antimony preparation sodium thiogly- 
collate which is relatively non-irritating when injected intramuscularly. The 
toxicity of this drug is certainly less than that of tartar emetic which is now 
generally employed in the treatment of schistosomiasis (Chapter XX XI).
