The chief distinction between this experiment and those pre- 

 ceding lies in the rainy weather prevailing and the resulting 

 muddy condition of the corral. The results coincide with those 

 of the former experiments in that infection was not demonstrated 

 to persist in the corral for one day. 



Experiment U. — This experiment was essentially a duplication 

 of experiment 1, except that the carabao wallow was covered on 

 top and on three sides with a bamboo and grass roof. 



The corral had been infected by the presence of carabaos 3085 

 and 3086, both in a stage of the disease corresponding to the 

 sixth day following the initial rise of temperature. During the 

 last twenty-four hours that these animals were in the corral, 

 bull 2999 was kept with them as a control to show the existence 

 of infection. The animal was removed, isolated, and developed 

 rinderpest. During the day previous to removal, the sick cara- 

 baos occupied the wallow and defecated therein. The details 

 regarding the exposure of the animals in the corral appear in 

 the notes below. 



April 2, 1911. Bulls 3085, 3086, and 2999 were removed from the corral. 



April 3. Bull 3104 was turned loose in the corral; it was seen to drink 

 from the wallow. Sky clear and air dry. 



April 4. Bull 3104 was still in corral. Sky clear and air dry. 



April 5. Bull 3104 was removed from corral, disinfected, and segregated 

 with controls against accidental infection. Carabao 3079 was put in the 

 wallow on this date, being led through the corral with pads on his feet 

 soaked in disinfectant. Rain occurred during the night. 



April 6. Carabao 3079 was removed from corral, and immediately dis- 

 infected and segregated with control. Rain occurred during the morning. 



April 7. Carabao 3090 was put in wallow in the corral with the same 

 precautions as taken with carabao 3079. Sky clear and bright. 



April 8. Carabao 3090 was removed from corral, disinfected, and iso- 

 lated with control. Sky clear and air dry. 



April 9. Carabao 3087 was turned loose in the corral, and was left 

 in corral one week. Sky clear and air dry.
