750 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [2] 



1 have prepared eight solutions coutaining 35 grams per 1,000 of dis- 

 tilled water, of the fellowing substances : 



Solution 'So. 1 : Chloride of sodium iff o 



No. 2 : Chloride of magnesiiira ^. two 



No. 3 : Sulphate of magnesia tfto 



No. 4 : Bromide of potassium y^§o 



No. 5 : loduret of potassium rtlo" 



No. 6 : Chloride of potassium yff ^ 



No. 7 : Sulphate of soda j-|f^ 



No. 8 : Sulphate of potash j^^ 



Here we have eight solutions, each containing one of these natural 

 elements of the sea-water, in the proportion in which it contains all of 

 them. The sulphate of soda alone does not belong, properly speaking, 

 to sea-water, although its elements are contained in it. 



Three other solutions have been prepared, in which all the elements 

 are found united, but in which the quantitative preponderance which in 

 the water of the sea belongs to the sea-salt, is given (1) to chloride of 

 magnesium, (2) to chloride of potassium, (3) to sulphate of magnesia. 

 The following is the composition of these solutions : 



Solution No. 9 : 



Chloride of magnesium 27. 00 



Chloride of potassium 0. 75 



Chloride of sodium 3. 70 



Sulphate of magnesia 2. 30 



Sulphate of lime 1. 50 



Bromide of potassium 0. 02 



Distilled water 1000. 00 



Solution No. 10 :

Chloride of magnesium 3. 70 



Chloride of sodium 0. 75 



Sulphate of magnesia 2. 30 



Sulphate of lime . . 1. 50 



Bromide of potassium 0. 02 



Distilled water 1000. 00 



Solution No. 11 :
