                                Study of eudiometer apparatus, used to measure changes in the volume of a gas subjected to physical or chemical reactions. 
The accompanying article states that: ‘This apparatus, (Plate IV) which is of easy construction, and extremely portable, consists of a glass measure M, fig.1, graduated into hundred parts; a small gum-elastic bottle B, fig.2, capable of containing about twice the quantity of the measure…a glass tube, T, fig 3, also graduated…into thousand parts of the measure…a small steel cock, which is secured into the neck of a very small gum-elastic bottle…SB, fig. 4…a pair of circular-mouthed forceps, lined with cloth, which firmly grasp the measure, fig.5’.
Plate 4, illustrating the paper: ‘A new eudiometer, accompanied by experiments elucidating its application. By William Hasledine Pepys. The Philosophical Magazine…[edited] by Alexander Tilloch, v.29, (1807-1808) pp.116-126.
Inscribed above: ‘Philo. Mag. Vol.XXIX. Plate IV. Pepys’s Eudiometer’. Inscribed below: ‘S. Porter sculp. 114’.
William Haseldine Pepys (1775-1856), British surgical instrument maker and natural philosopher, was elected a Fellow of the Royal Society in 1808.
