This is a semi-micro Kipps apparatus. The solid reagent (zinc, marble, iron sulphide, etc.) is placed in a large test tube with holes in it, and the acid is having in a jar or other receptacle. A series of holes is made in the bottom of the test tube using a blowpipe and playing a fine jet, single shot at a time, until the glass is pierced. Glass beads, or short lengths of glass tube placed vertically, are put on the bottom of the test tube to serve as a platform for the solid reagent.
