146 Halket.—The Effect of Salt on the Growth of Salicornia . 
These results are represented graphically in Diagram i, where the varia¬ 
tion in height is plotted against the variation in salinity. 
This diagram shows clearly that plants of Salicornia flourished best in 
the presence of a certain amount of salt, though growth was retarded if the

amount of salt present increased beyond a certain limit. In these experi¬ 
ments the greatest growth took place in the pans treated with the 1 % 
solution of Tidman’s sea salt. The effect of salt on the growth of Suaeda 
maritima is not so clearly shown, as in one case it slightly increased the 
growth and in the other slightly decreased it. The plants were measured 
again on June 16, when the same variation in growth was found. A number
