ON THE MANUFACTURE OF CHLOROFORM. 225 
facture may be carried. M. Louis Kessler, in a communica- 
tion published in the Journal de Pharmacie for March, 
gives some satisfactory results as obtained in the laboratory 
of MM. Woehrlin and Kessler, of Strasburg, the facts of 
which we now offer, together with a figure of the apparatus 
employed. 
The cylinder or vessel to contain the materials for gene- 
rating the chloroform, was first constructed of lead, but 
subsequently a strong wooden cask was employed, with the 
same success, which is figured above. The cask is placed 
on a suitable frame, on one of its ends ; through the centre 
of the upper head passes an axel B, the joint air tight, the 
lower end entering a cap attached to the lower head, which 
axle has four arms, and is caused to revolve at will, by a 
crank. At A is a large opening, by which the chloride of 
lime and water are introduced. Another and much smaller 
one gives passage to the lead tube c c' designed to conduct 
away the vapours, whilst the other side is pierced by the 
hole D, traversed by a lead tube of larger diameter, which 
communicates at will with the funnel 'at F and the small 
iron boiler, by means of the two stopcocks, a and 6, of
