On the Temperature of the Frith of Forth. 



Table shewing the Temperature of the Air and Sea, and the Specific 

 Gravity of Sea Water ^ at Leithy from September 1842 to April 

 1843. 



It may be useful to insert another table, for which I am in- 

 debted to Mr Adie junior, shewing the mean monthly tem- 

 perature of the air, and the quantity of rain that fell in 1842, 

 and in the spring months of the following year, in the neigh- 

 bourhood of Edinburgh, viz. at Canaan Cottage, which is 246 

 feet above the mean height of the sea.
