These results have been corroborated by Halket. 1 An even 

 sample of plants was collected from one locality, the succulent 

 parts were removed and weighed, dried at ioo° C, and again 

 weighed ; from these data the amount of water in the succu- 

 lent parts was calculated. The succulent parts of other plants 

 were then immersed in water for certain periods of time, and 

 the amount of water taken up ascertained. 



In the case of Suceda maritima the percentage of water in 

 the leaves of freshly gathered plants was 88-6 per cent., but 

 after immersion in distilled water the amount of water rose to 

 90-4 per cent. Similarly in the case of Salicornia the initial 

 amount of water present in the fleshy parts was 90-2 per cent, 

 before, and 92-0 per cent, after immersion in distilled water. 



In other experiments the plants were removed from the 

 soil with their roots, as far as was possible, intact, and the 

 roots, with the adhering soil, were well wrapped around with 

 tinfoil. Then the fleshy parts were dipped into water, and, 

 after as much water as possible had been removed with filter 

 paper, weighed. The weight thus obtained was considered as
