Page 285 - To every quart of this add 10 to 15 drops of a saturated solution of indigo, completely neutral. After applying this dye to the wood, rub the latter with a saturated and filtered solution of verdigris in hot concentrated acetic acid, and repeat the operation until a black of the desired intensity is obtained. Oak thus stained is said to be a close as well as handsome imitation of ebony.
Page 262 - ... and solutions to which it has been added may be kept in covered vessels for months. All extract solutions lose strength on keeping ; during the first two months the solution may become 30 per cent, weaker ; then the strength remains nearly constant for eight months in the case of a solution of 1 : 18,000. Alcohol is almost as good an antiseptic as boric acid, if the solution be preserved in well-stoppered flasks.
Page 267 - is celebrated for its incredible powers of digestion. The abundance of pepsine, to which it owes this faculty, has created among the Indians a curious commercial fraud. They dry it and sell it literally for its weight in gold. It is used for the purpose of restoring worn-out stomachs." A London medical journal says: "We think 'ostrich pepsine' such a splendid name for business purposes that we wonder it has never been adopted. The pepsine of the pig would have no chance in competition with that of...
Page 455 - If then light, which has been previously polarized, be transmitted, it will be extinguished in the two parts of the field of view in positions which lie close together, and the light will become uniform in a position midway between these. This position determines the plane in which the incident light was polarized with a precision much greater than has been otherwise attained. Professor Jellett stated that the different observations did not differ from one another by an angle greater than a minute,...
Page 284 - The seaweed, called by the native name of tengusa, is carefully washed and afterwards boiled, so as to form a gluish decoction, which is strained off and put into square boxes. When cool, it forms a stiff jelly, which can easily be divided into squares a foot in length. The manner in which the surplus water is removed is very ingenious. The jelly prisms are exposed in the open air during a cold night, and allowed to freeze. During the day the sun melts the water, which runs off, leaving behind what...
Page 583 - WOOD stated that DR. J. COLLIS BROWNE was undoubtedly the inventor of Chlorodyne, that the whole story of the Defendant Freeman was deliberately untrue, which he regretted to say had been sworn to.— See Times, July 13, 1864.
Page 189 - Cucurbita perennis, called Chili Cojote by Mexicans. — The pulp of the green fruit is used with a little soap to remove stains from clothing. The roots of this plant are large and long, and when macerated in water are applied to piles, generally with good effect. The seeds are ground fine and made into mush and eaten as food by many Indians of Arizona and Southern California. Euphorbia polycarpa, called by Mexicans Golendrina. — A strong decoction made from this plant and applied to snake bites...
Page 570 - It would be difficult to praise the work too highly. All the merits which we noticed in the first volume are conspicuous in the second. The arrangement is clear and scientific; the facts gained by modern research are fairly represented and judiciously selected ; and the style throughout is singularly lucid.
Page 266 - C , even for twenty-four hours, failed to destroy the bacterial germs, five minutes' exposure to one of 125° C. to 150° C. invariably succeeded, and the test fluid remained clear even for eleven days or longer. Dr. Wernich specially reminds us that his •results must not be taken as applicable to all forms of bacteria, some of which probably require severer measures for their complete destruction. He also points out that it is easier to disinfect wool than linen, and that cotton wadding is the...
Page 468 - Having frequently tried this test, and finding it extremely useful both as a qualitative and as a quantitative process, it appeared to me desirable to ascertain to what extent it might be advantageously employed in the testing of powdered vegetable drugs. As many of the latter are lighter than chloroform, and the usual mineral adulterants sink in that liquid, it was but reasonable to infer that this mode of separation might prove of value to the pharmacist. I will not trouble the meeting with the...
