ANALYSES. 



In eacli case I have determined : 



(1.) The weight of the beets. 



(2.) Specific gravity of tlie juice. 



(3.) Water in the juice. 



(4.) Cane sugar in the juice. 



•(5.) Substances in juice other thaii cane sugar (by dif- 

 ference.) 



The beets were carefully cleansed by brushing and rub- 

 bing, without washing, and grated by hand on a large tin 

 grater. The pulp was subjected to pressure in thick cloths, 

 or in an iron screw press. 



The method of analysis was, briefly, as follows: The 

 water was determined in the usual w^ay by heating a certain 

 portion mixed witli a weiglited amount of pure, dry sand, 

 at 212° F. until the w^eight remained constant. 



The sugar Avas determined in an accurately measured por- 

 tion of the juice by means of an excellent " polariscope."* 



The determinations Avere duplicated in almost every case, 

 and the figures given are the average of all observations.

-lam deeply indebted to Dr. Arno Behr, of the sugar refinery of 

 Messrs. Matthiessen & Wiecliers. Jersey City, for the loan of a valuable 

 iustrument, by which I was enabled to commence work promptly 

 without annoyance from a delay in receiving tlie instrument ordered 

 by the Department from Dr. Scheibler, of Berlin.
