In a previous memoir in tbe Transactions of tbe Society of 

 Sciences at Lille (1857), the author showed that at the time 

 when the seeds of the Beet reach maturity phosphoric acid was 

 no longer present in the root. This essay contains the result of 

 further observations relative to the " migration" of phosphorus ; 

 important as the element accompanying nitrogenous matter in 

 all phases of plant life. The cotyledons of seeds exhausted by 

 the development of young shoots are found to be destitute of 

 phosphoric acid, the ashes consisting in great measure of silica 

 and lime. Substances excreted by plants as gum and manna 

 contain no phosphorus. The author remarks the presence in 

 notable quantity of phosphoric acid in marine Algae and Zost,era, 

 while analyses of sea-water aiford no trace of it and conjectures 

 the possibility that in the sea the phosphates may exist in com- 

 bination with animal matter, as in the unctuous film found float- 

 ting upon its surface. In pollen (of the White Lily) M. Coren- 

 winder states that a larger proportion of phosphoric acid was 

 found than in the seed of wheat. The acid was also found in 

 the spores oi Lycopodium clavatum.
