180 Report on Weights and Measures. 



all existing contracts or rents payable • in corn should be cal- 

 culated according to these Tables of equahzation. 



Dr. Wollaston in his examination before the committee made 

 the following remarks : 



There is one standard of capacity that would be particularly 

 advantageous, because it Avould bear simple projjortions to the 

 measures now in use, so that one of the great inconveniepces 

 arising from change of the standard would be obviated, by the 

 facility of making many necessary computations without reference 

 to Tables, 



If the gallon measure be defined to be that which contains 

 10 lb. of water at 56f, 



Then since the cubic foot of water weighs 1,0U0 oz. at 56|, 

 4 pint = 10 oz. = y~ of cubic foot = 17'28 inches. 

 Pint = 20 oz. = 34-56. 

 Bushel = SO lb. = 2211-84. 



And the simple proportions above alluded to will be found 

 as follows : 



Cubical Inches. 



The gallon of 10 lb. = 276*48 xff= 2S2-01j282 Beer gallon. 



Also.... - = 276-48x|2-= 230-40 231 Wine gallon.

The following mode of defining the standards of length, weight 

 and capacity, is submitted to the committee on weights and 

 measures, as the most distinct answer to their inquiries :
