with virulent blood. Tests made at five, thirteen, fifteen, seven- 

 teen, nineteen, and twenty-one days gave negative results. 



Experiment 15. — The blood of an animal infected with rin- 

 derpest was shown to transmit the infection at six, eight, ten, 

 twelve, fourteen, and sixteen days after it had been injected with 

 virulent blood. 



Experiment 16. — Urine collected from an animal on the 

 seventh day of febrile temperature was diluted with an equal 

 amount of water and sprinkled on a grass plot. An animal 

 grazing over the "grass plot twenty-four hours later failed to 

 contract rinderpest. 



Experiment 17. — Urine from infected animals, at stages of 

 attacks of rinderpest corresponding to the fourth and eighth days 

 of febrile temperature, was diluted in water and sprinkled on 

 grass. An animal that grazed on the spot thirty-six hours later 

 contracted rinderpest. 



Experiment 18. — Urine from an animal six days after in- 

 oculation in the third day of febrile temperature of an attack 

 of rinderpest was sprinkled on a grass plot. An animal that 

 grazed thereon forty-eight hours later did not contract the dis- 

 ease. Tests were made of the same urine at seven and eleven 

 days after inoculation, the grass plot being left unoccupied 

 twenty-four hours, but negative results were obtained. 



Experiment 19. — Urine of two animals both at a stage of an 

 attack of rinderpest corresponding to the sixth day after inoc- 

 ulation and third day of febrile temperature was mixed, diluted 

 with water, and sprinkled on grass, but did not cause infection. 

 Urine of another animal seven days after inoculation gave neg- 

 ative results. 



Experiment 20. — Urine from an animal five days after in- 

 oculation and two days after initial rise of temperature, when 

 diluted with water and sprinkled on grass, proved to be infec-, 

 tive after thirty-six hours. 



Experiment 21. — Urine from an animal eight days after in- 

 oculation, two days after initial rise of temperature, did not re- 

 main infective on grass after thirty-six hours. 



Experiment 22. — Urine and faeces together, from an animal 

 eight days after inoculation, three days after rise of tempera- 

 ture, when diluted with water and sprinkled on grass, did not 

 prove infective forty-eight hours later. Faeces from the same 

 animal twelve days after inoculation did not prove infective 

 after lying on grass for twenty-four hours. 



Experiment 23. — Faeces from an animal six days after inocu-
