Note C — II. DETECTION OF POISONS, THE PRESENCE OF WHICH IS SUSPECTED.
Jesse P. (Jesse Park) Battershall translation
The fusing of the point of the tube is also prevented by platinizing it. The tube is drawn out, its end roughened by filing, and then immersed in solution of bichloride of platinum, so that a drop or two of the fluid adheres. The point, upon heating, now acquires a fine metallic lustre, and by repeating the operation a few times a good coating of platinum is produced both on the exterior and interior of the tube.—Trans.
