The Biire;ui has recently made the following experi- 

 meuts upon chickens to determine in what doses tur- 

 pentine may be administered to them without danger. 

 As in the experiments vvitli bluestone cited belOiW, a 

 small rubber tube was inserted through the mouth to 

 the crop, and the medicine forced through the tube 

 with a large bulb pipette. This insured the deposit of 

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

 excellent method of administering the liquid, since it 

 caused no pain to the animal, a chicken's gullet being 

 quite large and easily admitting a 3-lG inch (outside 

 measurement) rubber tube. 



No. 121. Full-grown chicken. 



Jan. 13, dosed with 5cc turpentine. Effects- Slight diarrhoea. 



Jan. 16, dosed with locc turpentine. Effects: Severe diarrhoea: 

 animal sick and listless; complete recovery in three days. 



No. 122. One-year-old chicken. 



Jan. 13, dosed with lOcc turpentine. 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 30>-c turpentine. Effects: Very severe 

 diarrhoea; animal very sick and refusoil 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 15'='' 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 (14.7S5CC) of spirits of turpentine injected through a 

 rubber tube directly into the crop. The experiments took place 

 from February 19 to February 25. 1S96.
