Draughts of a stated velocity and containing a fixed amount of firedamp are produced in this gallery. All this is perf...ormed by producing depressions at one end while the air and firedamp penetrate at the other end of the gallery.

The other end is not entirely free, being closed by a parti- tion perforated with holes which are apertures with thin- walls the size of which can be made greater or lesser according to the volume of air required for each aspiration of the Koerting. The firedamp is introduced in the gallery at little dis- tance from tho aperture v.
