Note.— In one of the waters from the quarry mud, the total carbonic acid found in 1 litre = Q-6500 grammes. 

 Carbonic acid calculated from the alkalinity = 0"3414 „ 



Difference = 0"3086 (which is nearly bicarbonate).

Note. — In the 4th portion, the total carbonic acid fonnd = 0*5954 grammes. 

 Carbonic acid calculated from the alkalinity = 0"5545 „ 



Difference = 0"0409 extra carbonic acid. 

 * All the analyses in connection with this paper have teen conducted, under our supervision, by Mr W. S. Anderson, F.C.S., Chemist at the Marine Station, Granton.
