PLATE I. 
Description of the Apparatus represented in section, and to a scale of one-fourth. 
Fig. 1. The steam-globe (2076.), principal steani-cock, and drainage-cock to re- 
move the water condensed in the pipe. The current of steam, &c. travelled in the 
direction of the arrow-heads. 
Fig. 2. The cone apparatus (2077-) in one of its forms. The cone could be ad- 
vanced and withdrawn by means of the milled head and screw. 
Fig. 3. The feeding apparatus (2078.). The feeder was a glass tube or retort neck 
fitted by a cork into the cap of the feeding stop-cock. Other apparatus, as that 
figured 2, 5, 6, could be attached by a connecting piece to this apparatus. 
Fig. 4. The chamber C (2079.) fitted by a cork on to a metal pipe previously 
screwed into the steam-globe ; and having a metallic tube and adjusting piece screwed 
into its mouth. Other parts, as the cone fig. 2, or the wooden or glass tubes 5, 6, 
could be conjoined with this chamber. 
Fig. 5. The box-wood tube (2102.). 
Fig. 6. A glass or thin metal tube (2076.) attached by a cork to a mouth-piece 
fitting into the steam-globe.
