I was obliged to abandon work on these seeds, for on account of 
handling them I had repeated and severe attacks of dermatitis from 
contact with the syrupy covering of the endosperm. The symptoms 
were identical with those of Rhus poisoning. 
5. THE Noppe-HANLEIN TABLE. 
Beside Chenopodium album, I have studied the following seeds 
mentioned in the Noppe-HANLEIN table: Aquilegia vulgaris, Cap- 
sella Bursa- pastoris, Lysimachia vulgaris, Plantago major, P. Rugelii, 
and Thlaspi arvense. It was found, in agreement with NoBBE and 
HANLEW, that all these seeds absorb water readily. 
In Aquilegia vulgaris NopsE and HANLEIN obtained a germina- 
tion of only 0.75 per cent. after sixteen days, and no more during 
the remaining three years. In all tests at 23° I found over 5° pe 
cent. germinating within thirty days. None generally germinated 
short of sixteen days because of the rudimentary state of the embryo. 
Breaking the seed coats cut down the percentage of germination by 
allowing infection by fungi which the slow growing embryos were 
unable to resist. 
Table VIII shows the germination of seeds of Plantago major, 
P._Rugelii, and Thlaspi arvense at 18-22° and 28-33° with seed 
intact and seed coats broken. It is seen that with seed coats broken 
and with favorable temperatures over 95 per cent. germinate 17 
every case. These results should be compared with Table I, in which
