Sayfa 107 - ... of such a size as to yield at least 5 pounds of coal per foot of thickness of coal bed — that is, 5 pounds for a bed 1 foot thick, 10 pounds for a bed 2 feet thick, 20 pounds for a bed 4 feet thick, etc. 4. All material encountered in such a cut should be included in the sample, except partings or binders more than three-eighths inch in thickness and lenses or concretions of sulphur...
Sayfa 366 - F.), add it to the Linseed Oil, and mix thoroughly ; then incorporate the Alcohol and continue the heat (without stirring) until a small portion of the mixture is found to be soluble in boiling Water without the separation of oily drops. Then allow the mixture to cool, and transfer it to suitable vessels. The Potassium Hydroxide used in this process should be of the full strength directed by the Pharmacopoeia (85 percent.).
Sayfa 222 - Agitate by either shaking or stirring occasionally for several hours and leave over night. Wash by squeezing through linen, continuing the washing until the wash water gives no precipitate with barium chloride. Squeeze the hide using a press if necessary, so that the wet hide will contain between 70 and 75% of moisture.
Sayfa 223 - F. Swedish recommended) of size sufficient to hold entire filtrate, returning till clear. Evaporate 100 cc of the filtrate. The weight of the residue must be corrected for the dilution caused by the water contained in the wet hide powder. The non-tannin filtrate must not give a precipitate with ai% gelatin.
Sayfa 223 - ... greater than 3 inches in diameter. V. DETERMINATION OF TOTAL ACIDITY OF LIQUORS. (17) Place 100 cc. of the liquor in a 500 cc. flask and make up to the mark with water. To 100 cc. of diluted liquor in a flask with tube condenser, add 2 grams of chemically pure animal charcoal. Heat to boiling temperature with frequent shaking, cool, filter and titrate an aliquot portion with decinormal alkali.
Sayfa 129 - ... grouping analyses of rocks. We may then note among the elements mentioned such of the metals as have just been cited and may remark the rarity of the others; we may next set forth the necessary percentages of each metal which make a deposit an ore, that is, make it rich enough for profitable working. By comparison we can grasp in a general way the amount of concentration which must be accomplished by the geological agents in order to collect from a naturally lean distribution in rocks enough...
Sayfa 394 - The rise and fall in the amounts of outgoing phosphorus compounds occurred almost wholly with the inorganic salts found in the egesta. The organic phosphorus bodies of the egesta were but little affected, if at all, by the proportions of phosphorus compounds in the food. Variations in the phosphorus supply appeared not to modify the appropriation of this element by the milk.

Sayfa 594 - ... energy requirement. Knowing that the law of the conservation of energy obtains in the human organism, it is only necessary to know the energy output per day to determine the energy requirement, for the energy output is practically the energy requirement. With the respiration calorimeter, a chamber in which a man may live...
Sayfa 221 - Sample must be dried at a temperature not exceeding 60° and then ground to such a degree of fineness that the entire sample will pass through a sieve of 20 meshes to the inch (linear). 3. Amount of Sample and Proportion of Water for Extraction. — For fresh materials the amount of sample and proportion of water for extraction should be such as to give between 0.35—0.45 grm.
