A TABLE of the Specific Gtavities of the Mixtures of Alcohol and "Water, witli the 



Proportion of thefe Fluids at the Temperature of 60 Degrees of the bcale of Fahrenheit, 



12,44 °^ Reaumur, 15,55 °^ ''^^ Decimal 1 hermometer. 

 N'/c. I haye placed in this table the ratios publithed by Citizen Chaiiflisr, from the 



Memoirs of Citizen Gouvenain, at the article Alcohol of the Encyclopsdie Methodique,. 



and thofe given in the tables of Mr. Gilpin, which are recommended by the philofophers 



of Germany. Journ. Phyf. de M. Grcn, 1796, Tom. III. p. 128. 



We (hall not be furprifed at the difference between thefe two tables, if we attend to the 

 circumftance that the alcohol ufcd by ChaulTier was more highly rc£lified, its fpecific gra- 

 vity Iiaving been only 0.798 at the fame temperature at which the fpirit ufed by Gilpin 

 gave .0825. But it is not eafy to conceive that this difference could produce fo confiderable 

 a change in the penetration or diminution of volume of the mixtures ; that indicated by 

 Gilpin at equal parts of fpirit and water being c.025, whereas, according to Chauffier, it 

 is 0.0454 f.

' By meafure, the water being added as tlic fpirit is diminillicd, fo as to keep the volume conllantly = 100. 



f For want of that part of the New Encyclopedic which contains the tables of ChaulTier, I am not qualified 

 to give .in account of tlic degree of accuracy they may polTefs. The tables of Gilpin are to be found in the 

 fccond part of the Philofophical Tranfaflions for 1794. They arc comprehended in one hundred quarto pages, 

 and exprefi — for every finglc degree of Fahrenheit, from 30" to 80° indufive; — and for all mixtures of ardent 

 fpirit «nd water, formed by the addition of i , 2, 3, &c. parts by weight of water, a', far as 100, to the conftani 

 ijuantity leo of fpirit, at 0.815 fpecific gravity when at Oo ;— and for all mixtures formed in like manner by
