Radicles of Maize. Seeds germinated on wet sand & were then pinned to cork lid with sqr of sand-paper affixed to them at 8° a.m on June 28th 1878. No memorandum was made at time of shape of radicle; but I never affixed square except to ones approximately straight. —The following sketches

& note were made on 29th. at 8° a.m. ie after 24°. The sole doubt is whether the radicles naturally grow contorted. If they do not do so. There can be no doubt that the contact has greatly affected them.
