BABCOCK MILK TESTER. 



303 



In watering this milk the fat and the solids not fat are 

 diluted or reduced in the same proportion, in the above 

 illustration one-fifth. 



Ordinary milk with 4 per cent of fat should have over 9 

 per cent of solids not fat, and the discrepancy between 

 9.40 and 7.68 tells the watery story. 



The chemist whose analysis reached such results as fat, 

 4, solids not fat, 7.(38, total, 11.08, would have no hesita- 

 tion in making oath that the milk was absolutely watered. . 



The Dairy Bureau recently secured the conviction of a 

 person for selling two samples of milk which tested as fol- 

 lows : — 



Fat, 



Solids not fat, 

 Total, . 



These were suspicious samples, and the chemist felt that 

 there was a strong probability that the milk had been arti- 

 ficially watered. The producer of the milk, however, testi- 

 fied under oath that the milk had been under his control 

 and supervision every moment from the time it was drawn 

 from the cow — a Holstein — until the detective ofiicertook 

 the sample, and that no water had l)een added to what the 

 cow ])ut in it naturally. This did not save him from being 

 adjudged guilty, because it is against the law to sell milk 

 of less than average quality even if it is honest ( ?) milk. 



For the purpose of enforcing the law, milk that has l)een 

 artificially watered from the pump or faucet, and that which 

 has been naturally watered more than the average, are 

 treated alike ; l)ut there is a possibility that the above })ro- 

 ducer told the truth, and that the milk alluded to ma^' have 

 been free from artificial watering, because the solids not fat 

 are considerably over 8 per cent. 



In contrast with this was a case which the board of health 

 had last year. It attracted considerable attention and sym-
