From these results it appears that when the gangways are thoroughly carpeted the Members’ Gallery shafts supply rather more air, but that when the carpeting is imperfect no such improvement takes place. It is also seen from the last test in the table that when the extract fan’s speed was slowed down, the air-flow up these shafts increased. Inference. Under no conditions examined did the quantity of air passing up these shafts suffice for more than 25 persons. Yet the galleries to which they go seat 108.
