SPECIFIC GEAVITY INSTRUMENTS. 



The increasing use of these instruments in the arts and manufactures is intended to 

 be met in the following list, in which economy, as well as precision, has been 

 studied alike in those for manufacturing purposes, as well as the most refined inves- 

 tigations. L. CASELLA having manufactured about one thousand hydrometers for the 

 English and American Governments, the following official reports were made re- 

 specting them : " Those made by CASELLA are the best adapted for practical work, 

 In shape and strength they are by far the best. In respect to accuracy, CASELLA'S 

 are incomparably the best, and he deserves credit for the care with which he has 

 made them." Report of the Kew Observatory Committee to the British Associa- 

 tion, 1854-5.
