Radicles of Maize. Seeds germinated on wet sand & were then pinned to cork lid with sqr of sand-paper affixed to them at 8º 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 8º a.m. ie after 24º. 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.
