362 THE ANALYSIS OF MILK AND MILK PRODUCTS. XV. 



The difficulty of choosing a satisfactory standard is great, 

 and perhaps almost insuperable, when the great differences 

 which are often shown between evening's and morning's milk 

 are taken into account. If cows could be milked at regular 

 intervals of twelve hours each, these differences would be 

 greatly diminished, but unfortunately the exigencies of the 

 trade almost necessitate great inequalities in the intervals 

 between milkings. A different standard for morning and for 

 evening milk would, perhaps, better meet the case ; but, in 

 practice, difficulties in administering the law would arise. 



It is, however, highly desirable that an authoritative state- 

 ment should be made as to the exact meaning of the new 

 Regulation. Whether it is to be understood that all milk sold 

 to the public must contain at least 3 % fat and 8-5 % solids not 

 fat, or whether, so long as the sample can be proved to be the 

 genuine product of the animals, the existence of lower values 

 for fat and solids is not sufficient to ensure conviction," seems 

 at present to be uncertain." 



* From ;i circular, issued by the Board of Agriculture on Dec. 28th, 1001, it appears 

 probable that the latter interpretation is desired, but that if the fat in milk be found 

 to be below 3%, the onus of proving the genuineness of the sample then falls upon the 

 purveyor.
