38S BENJ. PIKE'S, JR., DESCRIPTIVE CATALOGUE. 



Tables arranged for Baume's Hydrometer t for Syrups, 

 Sfc., at GO degrees of heat, showing the Specific Gravity, 

 and the Quantity of Sugar in Pounds and Ounces in 

 the Wine Gallon of the Syrup. 



Baume's Hydrometer, or Sacrometer for Syrups, is equally adapted 

 for acids, leys, and other liquids heavier than water. This instrument 

 is of all others the one in greatest use ; the scale or numbers on the 

 stem however are arbitrary, and formed, as most others, after the 

 ideas of their projectors, and having no particular reference by which 

 they may be understood. The above table is designed to supply this 

 deficiency, and fix the value of the numbers in the scale, Thus at 

 13 the specific gravity is 1.100 or one tenth heavier than water, and 

 the solution contains 2 pounds 3 ounces of solid matter in the gallon. 



Price, in glass, 75 cts. ; extra large, $1 50 ; brass, $4; silver, $6. 



Price of Trallis's Hydrometer for Spirits, 10 to 14 inches, $1 ; 14 

 to 17 inches, $2 50 ; the same with thermometer, $3 50. (See p. 389.)
