Stran 337 - That the only preservative which it shall be lawful to use in cream be boric acid or mixtures of boric acid and borax...
Stran 194 - I let up some solution of liver of sulphur to absorb the dephlogisticated air, after which only a small bubble of air remained unabsorbed, which certainly was not more than -j-^ of the bulk of the phlogisticated air let up into the tube ; so that if there is any part of the phlogisticated air of our atmosphere which differs from the rest and cannot be reduced to nitrous acid, we may safely conclude that it is not more than T^ part of the whole.
Stran 216 - The Nomenclature of the New York Series of Geologic Formations' (Science, 8 Dec. 1899), and 'American Geologist' (February 1900). See AGE; CENOZOIC; ERA; FORMATION; MESOZOIC; PALEOZOIC; QUATERNARY; SECONDARY; SERIES; SYSTEM ; TERTIARY. Periodic Law, in chemistry, the law which teaches that the properties of the elements are periodic functions of the atomic weights ; so that when the elements are arranged in the order of increasing atomic weights, similar properties recur periodically, as we proceed...
Stran iii - THE MASSACHUSETTS INSTITUTE OF TECHNOLOGY. The objects of this Society are to awaken and maintain an active interest in the practical sciences, and to aid generally in their advancement and development in connection with arts, agriculture, manufactures, and commerce.
Stran 178 - ... a pursuit of our total perfection by means of getting to know, on all matters which most concern us, the best which has been thought and said in the world...
Stran 234 - C.-EA, 1901: Typhoid Fever at Newport, RI, in 1900 and Its Relation to Defective Sanitation.
Stran 358 - ... sensible heat of the rock is small compared to the heat of vaporization of the water it contains. Generalized solutions to the analysis have been prepared for these limiting cases, using spherical and cylindrical heat sources operating at either constant temperature or constant power. Typical results are shown in FIGURES 2, 3, and 4. FIGuRE 2 shows the rate of water produced as a function of time (on a dimensionless basis) and as a function of the dehydration, environmental and heat-source temperatures...
Stran 343 - In both the solid and porous cinder concrete many rust spots were found, except where the concrete had been mixed very wet, in which case the watery cement had coated nearly the whole of the steel like a paint and protected it. "Some...
Stran 123 - Witte's peptone, and 10 per cent gold label sheet gelatin. 7. Warm on water bath, stirring till peptone and gelatin are dissolved and not allowing the temperature to rise above 60
Stran 342 - ... up. At the end of three weeks the briquettes were carefully cut open and the steel examined and compared with specimens which had lain unprotected in each of the tin boxes. Those specimens which were mixed of neat cement can be dismissed without discussion, for the protection was perfect. The steel was as bright as when put in.
