An incomplete trial, incomplete on account of the disarrangement 
of the apparatus on the 450th hour, gave even lower germinations 
for maize than heretofore reported. From 11 A. M., Mar. 16, 1885, 
to 4 P. M., April 4, the temperatures maintained varied from 37° to 
42° KF. The examination of the thermometer in with the seeds, as a 
check upon the thermostat, counted 210 readings. Of these four 
were 37°, one 373°, twelve were 38°, twenty-eight were 384°, one 
hundred and eight were 39°, twenty were 393°, thirty-two were 40°, 
one was 404°, two were 41°, and two were 42°. The two 42° read- 
ings were at 9 and 10 A. M., April 3, when the apparatus halted un- 
til the rise was discovered, the 8 and 11 A. M. readings being 40°. 
We may hence say that the germinations that occurred were be- 
low 41° F. 
The Chester County Mammoth showed first germination in 430 
hours; the Waushakum in 460 hours, the Amber Rice so near ger- 
mination as to be doubtfully rejected. The apparatus after the 4 
P. M. count, April 4, was left exposed to the temperature of the of- 
fice, say 72° to 78° F., and at 8 A. M. April 5, or sixteen hours af- 
ter, the following per centage of germinations had occurred, viz : 
Germinated. Seed almost 
germinated. 
‘Chester County Mammoth Dent 100 per cent. 
Stowell’s Evergreen Sweet 73 per cent. 27 
‘Tuscarora Soft 92 per cent. 8 
Amber Rice Pop 100 per cent. oe: 
And at4 P. M. the germinations were noted at 100 per cent. for all, 
the radicles or acrospires extending from ¢ to 2 inch from the seed. 
CuRIOUS OBSERVATIONS UPON GERMINATION. 
March 12, 1885. Avery curious circumstance may be mentioned 
in regard to germination. After one box containing the seeds ex- 
posed” to low temperatures, below 45.3° for 520 and 396 hours was 
removed from its refrigerator, it was at once set over a gas flame in 
order that an hour or more boiling might destroy all germs of mold, 
and clean the cloth for further trials. After about one hour and a 
half boiling it was allowed to cool down a little, when it was acci- 
dentally looked into, and some seed left over was seen to be appar-
