Title	Unpublished paper, 'On the action of light on the colour of the river sponge (Spongilla fluviatilis)' by John Hogg
Date	9 May 1838
Description	Hogg observes that the green colour of the river sponge is acquired solely through exposure to light, and is lost when the sponge is kept away from a light source. As this does not appear to be the case with Actiniae [anemone] or the Hydra viridis [cnidaria], Hogg suggests that the river sponge is more closely related to algae or fungi than to any animal. Subject: Zoology / Botany Communicated by Thomas Bell. Written by Hogg in Temple, London. Whilst the Royal Society declined to publish this paper in full, an abstract of the paper was published in volume 4 of Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London [later Proceedings of the Royal Society] as 'On the action of light upon the colour of the river sponge'. A version of this paper was published by Hogg in the Magazine of Natural History: Hogg, John. 'On the Action of Light upon the Colour of the River Sponge'. The Magazine of Natural History, volume 4 (1840), pp. 259-168.
