The copper pail is filled with the gelatin tubes, and is placed on the water-bath, in which the water should be actively boiling. In from five to seven minutes steam will issue rapidly, from the tube in the cover, showing- that the temperature in the interior has reached 100°. The steam- ing is then continued for an additional 15 minutes. This process is now repeated, on each of the following two days. By m
