(5) Blood. — The peripheral blood does not appear to contain parasites. It 

 has been tested in some cases during life. 



O 



The heart-blood was found to contain a few parasites in the two cases 

 examined. 



(6) Kidney. — No parasites were found in this organ in the one case 

 examined. 



/ 



(7) Lungs and pleural fluid contain a few toxoplasms, at any rate in some 

 cases. 



(8) Aqueous Humour and Cornea. — jSTo parasites could be found in the two 

 cases examined (Mice C and J). 



(9) Brain. — No parasites were found in Mouse J. 



(10) Bone Marrow. — No parasites were found in Mouse L. 



(1) Experimental Infection of Mice.* 



Mice A and B were inoculated from the liver of a slightly infected pigeon 

 which was killed at Tunis on January 10. In all cases inoculation was intra- 

 peritoneal from peritoneal fluid unless otherwise stated. 



Mouse A. — Died January 17. Course of infection seven days. 



Only a little peritoneal fluid was present, but a number of parasites were 

 found, both free and intracellular. The liver contained a few, chiefly intra- 

 mononuclear parasites. 



Mouse B. — Died January 22. Course of infection 12 days. 



Very little peritoneal fluid and only a few parasites. Liver and spleen 

 scarcely any parasites. 



Mouse C. — Inoculated January 17 from A. Died January 25. Course of 

 infection eight days. 



Large amount of peritoneal fluid and many parasites here and in mesen- 

 teries. Left eye opacrue, but no parasites found in aqueous humour or cornea, 

 and lens appeared to be normal. 



Mouse D. — Inoculated January 25 from C. Died January 30. Course of 

 infection five days. 



Large amount of peritoneal fluid and numerous parasites in this and the 

 mesentery. 



Mouse E. — Inoculated January 30 from D. Died February 5. Course of 

 infection six days. 



Not much peritoneal fluid nor very many parasites. 



Mouse F. — Inoculated February 5 from E. Died February 12. Course of 

 infection seven days. 

 Large amount of peritoneal fluid, which was, however, poor in parasites. 

 * These inoculations were performed by Prof. Minchin under his licence.
