This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1886 edition. Excerpt: ... PRACTICAL CHEMISTRY. PART I. PRELIMINARY. To make a Washing Bottle.--Take a clean widemouth bottle, holding about a pint, and fit a good sound cork tightly into the neck. Then take a piece of stout glass tubing (about inch external diameter) and, with the aid of a cork borer, bore two holes through the cork, parallel to each other and of such a size that the tube will pass through with some friction. If you have not a cork borer of the exact size required, take one a little smaller and then enlarge the hole by means of a round file. Cut off a piece of the tube of about twice the height of the bottle. Draw off one end to a point in the blowpipe flame. Cut it off with a file and make the orifice smooth by holding it in the flame for a minute or two, taking care not to close it completely. Then, in a common fish-tail gas flame, bend the tube so as to B form an angle of about 6o at such a distance from the wide end that when the tube is passed through the cork it will reach well to the bottom of the bottle. Into the second hole in the cork another piece of the same tubing is fitted, but this is cut off just below the cork, and is bent to form an angle of about 120 . The open end, projecting upwards, should be made smooth at the edge, by holding it for a few minutes in quantities of water into test tubes and for general purposes as a store of water. It is used by blowing gently into the upturned end of the mouthpiece, and so producing a pressure upon the surface of the water in the bottle. To Fix a Platinum Wire into a Glass Holder.-- Take six inches of narrow glass tubing, and by holding it in the Bunsen flame soften it so that it may be drawn out in the middle. When cold, scratch it at the middle with a file and break it...
