 and 6880 was certainly high enough to have insured a pure coffee.

EXTRACTS. 



Three samples of coffee extracts were examined, viz : Serial Nos. 6875, 

 6805 and 6897. No. 6875 contained no caffeine. On further examina- 

 tion it was found to contain cereals or other starchy bodies and no 

 coffee. This sample contained tin and traces of copper. The former 

 amounted to 0.248 grams per 1,000 grams of the extract. 



Sample No. 6895 contained 1.19 per cent caffeine. This is about 

 Konig's mean (see p. 903) for roasted coffees ; hence pound for pound this 

 is about equal to average coffee. This sample contained considerable 

 dextrose.
