Nuttallia equi Horse I. 
The horse was inoculated subcutaneously with 5 c.c. of citrated blood at 10 a.m. on 
27. XI. 1909; the horse died 7. xii. 1909 (day 11).

Free parasites. 
From the following chart it will be seen that the parasites were first detected in the 
horse’s blood on the 8th day after inoculation ; their number rose so that about 5 of the 
corpuscles were infected on the 10th day, whilst on the day following about 4 % were 
infected. With regard to the percentage of different types of parasites encountered, one 
striking fact emerges, namely, that, relatively speaking, the number of free and small 
parasites greatly increased toward death and the number of medium and large sized 
parasites decreased. The rise and fall in the percentage of infected corpuscles accompanied 
the rise and fall in the body temperature.
