FOODS AND FOOD ADULTERANTS. 



fact is vrell known to me, as I have been called on to examine the commercial glucose 

 and have found that frequently there is a quantity of dextrin present. The same 

 specific gravity of two glucoses will frequently show as much as 40 points difference 

 on the polariscope. The numbers given on the table of the various samples will 

 show by reference to the numbers on the tables of soft sugars from whom they were 

 obtained, since in the purchase of the samples the effort was made to obtain from 

 the same person a sample of sugar, molasses, and honey. Consequently, I have not 

 repeated the name of the seller on the tables giving the result of the molasses and 

 honey analyses. The determination of the amount of ash was, as a rule, made by 

 taking three grammes of substance in a platinum dish of about 2.5 inches in diameter. 

 The reducing sugar has in all cases been calculated as dextrose. In giving the re- 

 sults of the honey analyses I have given one table containing them all, and a subse- 

 quent one where I have separated and classified the honeys as to their purity and the 

 adulterant made use of.

From some of the above there were two samples obtained, and samples of sirup ob- 

 *ained from all. 



The accompanying tables give the result of the analyses, and in the case of honeys 

 I have separated those which appear to be pure from those which are adulterated. 

 The numbers of the different samples indicate by reference to the list of samples what 

 the brand or mark was, as well as from whom purchased. 



All of which is respectfully submitted.
