TABLE OP THE SOLUBILITIES OF VARIOUS SALTS IN WATER. 



The following table, giving the solubility of certain salts used in 

 agriculture, may be useful. One hundred parts by weight of water at 

 the temperatures stated, dissolve the following parts by weight of the 

 various salts l : 



THE BRITISH AND METRIC SYSTEMS OF UNITS OF LENGTH, AREA, 

 VOLUME AND WEIGHT. 



The inconvenience and cumbrousness of our British system of 

 weights and measures have too often been pointed out to need further 

 reference here ; but in agricultural matters, perhaps, more than in 

 other commercial branches, the inconsistencies of the current systems 

 of units are strikingly evident. In addition to the disadvantages 

 common to all our measures and weights, there are such anomalies as 

 selling grain nominally by volume (bushels and quarters) and then 



1 Taken chiefly from Comey A Dictionary of Solubilities, 1890. 



2 Most soluble in water at 35 ; 0-279 parts then dissolve. 



3 Is most soluble about 38, when 100 parts of water dissolve 51-67 parts of the 

 anhydrous salt or 1142 parts of the soda crystals. 



4 Is most soluble about 33, when about 412 parts of the decahydrated or 50-6 

 of the anhydrous salt dissolve.
