Summary. 
The results of the above described experiments suggest that Abder- 
halden’s reaction may be of use in the study of protozoal diseases. 
In the case of East Coast Fever it is seen that in early stages of the 
disease only the lymphatic and suprarenal glands seem to be affected, 
whilst in later stages destruction of tissue takes place in practically 
all the organs, and this corresponds with the results of microscopical 
examinations of the various tissues. 
Various experiments were performed with dogs infected with Babesia 
canis, but in most cases, owing to the presence of haemoglobin in the 
serum, the controls gave positive results as well as the organs + serum. 
The blood of a dog taken at the commencement of the infection was 
found to contain substances having a destroying action on liver tissue, 
but not on the other organs employed, whilst in later stages of the 
disease practically all the organs were affected.
