The Bure;iii has iecen(l.y ina<le the f(»llo\viii<; rxpcii- 

 inents upon chickens to determine in wluii Moscs tin- 

 pentine may be administered to them wilhoiU danger. 

 As in the experiments witii blnestone ciled belo-w, a 

 small rubber tube was inserted throui;h the month to 

 the crop, and the medicine forced through the tube 

 with a large bulb pipette. This insured the de])0sit of 

 the entire dose into the crop, and proved to be a most 

 excellent method of administ(Ming the liquid, since it 

 caused no pain to tlie animal, n chicken's gullet being 

 (juite large and easily admitting a 3-10 inch (outside 

 measurement) rubber tube. 



No. 121. Full-grown chicken. 



Jan. 13, closed with 5cc turpentine. Effects: Slight diarrhoea. 



Jan. 16, dosed with 15cc turpentine. Effects: Severe diarrhoea; 

 animal sick and listless; complete recovery in three days. 



No. 122. One-year-old chicken. 



Jan. 13, dosed with lOcc turpe'ntine. Effects: Moderate 

 diarrhoea. 



Jan. 16, dosed with 25cc turpentine. Effects: Very severe 

 diarrhoea; animal quite sick and refused food; complete re- 

 covery in six days. 



No. 123. Full-grown chicken. 



Jan. 14, dosed with 15cc turpentine. Effects: Moderate 

 diarrhoea. 



Jan. 16, dosed with 30cc turpentine. Effects: Very severe 

 diarrhoea; animal very sick and refused food; complete re- 

 covery in six days. 



After performing these preliminary experiments in 

 the laboratory I requested Dr. Schroeder to treat a 

 larger number of fowls at the Experiment Station with 

 doses of IS'^^ turpentine, noting the age, sex, weight, 

 etc., of the animals. Of these experiments he has 

 handed me the following notes. 



Each chicken in the following table received a dose of one- 

 half ounce (14.78'i}C<^) of spirits of turpentine injected through a 

 rubber tube directly into the crop. The experiments took place 

 from February 19 to February 25, 1896.
