Muriate of soda, dried at temperature 212", 30.80 grains 



Magnesian salts, dried at about 212°, 4.01

the proportion of salt in 1000 grains of sea-water, 

 being between l-28th and l-29th, or 10-286ths, or 

 3,56 per cent. 



The annexed table exhibits the result of experi- 

 ments on the specific gravity of the sea, in different 

 parallels between 5T and 79°, made in various voy- 

 ages to the Spitzbergen whale-fishery *. 



* Since this Table was sent to press, an account of the 

 " Quantity of Saline Matter in the Water of the North Polar 

 Seas," by Dr Andrew Fyfe, has been published in the Edin- 

 burgh Philosophical Journal, No. I. Several of the specimens 

 of sea-water examined by Dr Fyfe, haviug been collected by 

 myself, in situations included in the annexed Table, it may 

 be interesting to subjoin an account of the quantity of " saline 

 jnatter per cent." procured from such specimens.
