tooled by the air striking the sides of the receiver. Finally, 

 the liquid falls into the flask beneath, this flask being insert-

Apparatus for the Fig. 571. 



Condensation of Gases. 

 (Fig. 5 71.) Consists 

 of a tubulated receiver, 

 supported on a retort 

 stand, at one of the 

 necks having a bent 

 tube, which enters one 

 of the necks of a three 

 necked bottle, passing 

 down nearly to the bottom ; the opposite neck having a bent 

 tube for passing the gas into a bell glass. This apparatus, 

 as arranged in the production of nitrogen from chlorine and 

 ammonia, is represented in the cut. The open pipe at the 

 side is supposed to be the beak of a retort in which chlorine 

 is being disengaged. It enters the globular receiver and 

 deposits condensed vapors. Then passing along the bent 

 tube, it arrives at the bottle, B, which is partly filled with 

 diluted liquid ammonia ; passing through the ammonia, it is 

 conveyed away by the pipe, c, into the jar, D. 



Price, with retort stand, $3.50.

Woolfs Apparatus. (Fig. 572, as above.) The most 

 elegant and convenient method of impregnating water with 

 an absorbable gas is by means of Woolfs apparatus, which
