Autograph draft leaf ‘p 10’ fragment in blue ink with pencil corrections of Earthworms (1881), unpublished paragraph (see p. 25). "Sense organ / That worms should be able to distinguish between the day & the night seems at first surprising, for they are furnished with eyes, not do they seem to possess any diffused sensitiveness to light as in the case of many lowly developed organisms; for I have repeatedly placed a candle close to them when out of their burrows at night, & though then very timid they never took the least notice of the sudden light. No doubt they could readily distinguish between the dry, warm air” Verso: Autograph draft leaf ‘(a)’ fragment in blue ink of Earthworms (1881), p. 21 |
