The followng was tried because out of 13 long radicles which had been thrice ‹dubbed› «touched or rubbed» «on theirtips^t6 Dec. 1' 1878» with n. of silver & much blackend, 6 had tips bent at rt ∠ or hooked, shwng tht one side «of apex» hd ben killed, «& these» all grew out sub-horizntally, as if Geotropism destryed — like Cieleski— Sachs¹ disputes, but these neither know of effects of oblique slices, & we now know tht irritatig one side «of apex» determines bendng. Therfor cuttng off tip tranversy probaly destrys th coordintng pwer & ‹radicle› «they» grow lawlessly.— I «fully»believe frm notes tht ‸^t7 12/13 grew out sub-horizntally, certainly 6/13 did so^t8
