 a jelly by boiling, is also used like gelose for food by the 

 Annamites. 



The marine plants which are employed as food and in 

 different industries in Japan are the following : —

 Musashi.

 on nearly all the coasts of Japan. It is simply dried and 

 sent into commerce. 



The kombou {Laminaria saccharind), which is one of 

 the principal products of Hokkaido. It is eaten in dif-

 China. 



Arame {Capea elongatd) is found principally in the seas
