Etching of fish. One lateral view of a shark and two views of the gills when the shark has opened its jaws. This image is archived with a text (attributed to 'A. I.') about fishes' swim bladders, which was read by Henry Oldenburg at the meeting of the Royal Society on 6 May 1675, and printed, with Robert Boyle's comments, in Philosophical Transactions of the Royal Society, vol. 10, no. 114 (1675).

Object history

At the meeting of the Royal Society on May 1675, ‘Secondly, a paper [was read] written by an anonymous author, containing a conjecture about the bladders of air, that are found in fishes, and the manner and organ, whereby fishes move to and fro in water, from one depth to another’ (Birch 3:219).
