tigates the structure and development of the mature embryo and 
of the seedling, and is to be followed by a research into the histol- 
ogy of the more advanced plant from good specimens in spirit. 
An important intermediate stage between these preserved young 
plants‘ and the growing seedlings remains to be supplied, and 
outgrowth, which remains in the axis of the seed, enve by 
the endospe g after the development and liberation of the 
cotyledons and their elevation by the elongating growth of the

till capable of 
furnishing considerable nutriment, Mr. Bower infers that the 
process serves 
this residual store of food. He therefore calls it “the feeder” in 
his description, speaking physiologically ; while morphologically 
it is of course likened to the “peg” of germinating squashes, the 
very different use of which, in riving the seed-coat and freeing 
the cotyledons, has recently been so well described by Darwin. 
The second point is that the seedling of Welwitchia promptly

habitat. For good specimens exhibiting flowers, leaves and ripe 
fruit, he will be glad to exchange specimens of European desider-
