A glass instrument to measure rainfall in Gresham College

The drawing shows a device to collect rain water, which was used by Henry Hunt at Gresham College. He collected rain water for an entire year between 12 August 1695 and 12 August 1696. The table with the results and this drawing of the device were printed in the Philosophical Transactions of the Royal Society, vol. 19, no. 223 (1696/7).

On 1[3] January 1697, 'Mr Hunts observations concerning the quantity of rain fallen at Gresham colledge for one year was read, it was ordered to be printed in the Transactions together with a Draught and an account of the Instruments with which they were made to be given by Mr Hunt next meeting' (JBO/10/11). There is no entry relating to this for the meeting of 20 January.
