Discusses funding and future experiments. Notes that the committee has also 'discussed drawings and proposals from many inventors sent to them for discussion by the Royal Society'; and that Professor Petavel has designed trench mortars operating by liquid carbonic acid, 'which have been submitted to Woolwich'.
