| Title | Unpublished manuscript, 'An account of some experiments exhibiting new instances of the absorbing power of steams; with a few remarks on the pulsation of jets' by G Robinson |

| Description | Robinson provides an account of three experiments which illustrate the absorbing power of a stream of fluid, whether issuing from the open mouth of a reservoir, or flowing through rigid tubes. The effects of this power are seen in the position of the fluid contained in a vertical tube open at both ends, placed within the reservoir, and of which one end is brought within the influence of the effluent stream, and also, when one end of a bent tube is brought into the stream issuing from the open orifice of a reservoir, while the other end is immersed in a coloured fluid. Robinson accounts for the intermitting or pulsatory character of the jet issuing from an open horizontal pipe, having a small hole on the upper side, by the introduction of air. The air, accumulating from time to time, forms a bubble. When the bubble has reached a certain size, it results in an obstruction to the free passage of the liquid until the obstacle is overcome by increased pressure from behind, and the jet then resumes its former velocity. These changes, occurring periodically, give rise to the appearance of pulsation which is observed in these circumstances. Includes four pages of figures showing the equipment and processes involved in Robinson's experiments. Marked on back as 'Archives 14 November 1844 S H C [Samuel Hunter Christie]'.
