A, Piédallu ; The acclimatisation in France of a rapidly 
growing tannin plant, the Canaigre (Ramex hymeno- 
sepalum). This plant comes from Arizona and the 
neighbouring regions, and gives tubercles containing 
28 to 30 per cent. of tannin. It has been proved to 
develop naturally in France, and survives the winter. 
It is rapid in growth, and should prove a valuable 
source of tanning material. Field cultivation experi- 
ments will be carried out.—M, Caullery and’ F.
