transplantation of organs undertaken by Theiler and Meyer, Koch’s 
granules are directly transmitted. These represent, under natural condi- 
tions, the stages which are formed only after the tick has transmitted the 
disease. The infection of the various glands in the body of an animal 
takes place through the blood current and accordinglyit becomes feasible 
to expect that the inoculation of blood also ought to produce the disease. 
A suitable occasion would probably arise when the plasma granules are 
found in the blood. Experiments to elucidate this will be carried out as 
soon as opportunity occurs. In an animal which was infected by the 
transplantation of organs I found Koch’s granules in the blood. Dr. Meyer 
showed me blood smears sent in from the practice in which a great number 
of mononuclear leucocytes contained the plasma bodies. 
Concerning the place of the East Coast fever parasite in protozology, 
the proposition of Bettencourt and others to separate it from the piroplasms 
and to substitute a new name {Theiler ia par va) is justified.
