Page 450 - in Tennyson's lines: How dull it is to pause, to make an end, To rust unburnished, not to shine in use.
Page 475 - thanks of the Society were voted to the President for his Address, and he was requested to allow it to be printed. The Awards of the Medals for the year were announced as follows, and the Medals were presented from the Chair :— The Copley Medal To Prof.
Page 447 - Strassen der sonst so belebt,en Weltstadt, ‘ outside,' auf dem Dach des Omnibus wie immer. Ich versank in Träumereien. Da gaukelten vor meinen Augen die Atome. • Ich hatte sie immer in Bewegung gesehen, jene kleine Wesen, aber es war mir
Page 228 - nutrition and life are satisfactorily maintained, at least for a considerable period, if the five aminoacids given be chosen from the more complex types, such as tyrosine, tryptophane, histidine, lysine and cystine, which experiment has shown to lie outside the range of the synthetic power of the animal body.
Page 479 - The Existence of Daily Growth-Rings in the Cell Wall of Cotton Hairs.” By Dr. WL BALLS. Communicated by Dr. FF BLACKMAN, FRS March 20, 1919. Sir JJ THOMSON, OM, President,. in the Chair. The following Papers were read :— I.
Page 229 - the dissociation of hydrogen and its apparent abnormal heat conductivity, and the dissociation of chlorine and oxygen ; also the chemical activity of dissociated hydrogen. His work on the emission of electrons from hot metals in high vacua led to the evolution of the “ kenotron “ and “ pliotron,” and of the “ half-watt “ lamp. His determination of the
Page 109 - The seventh heating was carried to 667° for quenching. This was a much larger temperature advance than in either of the preceding experiments, and was above the temperature of the third quenching, which was followed by very considerable generation of heat. But now there was very considerable absorption of heat, as shown in curve
Page 114 - round bars of Swedish charcoal iron, of the aggregate weight of the steel usually employed, were slowly heated to 960° and quenched. Complete loss of magnetic susceptibility had occurred at 801°. ¿ The bars were warmed about 3° just before being placed in the calorimeter. There was no trace of heat generation following the quenching. Indeed, the
Page 111 - hardening, or absorption of heat when quenched at rising temperatures below the lower critical temperature, after annealing, the following experiments were made with the carbon steel used for the first experiment described in the first paper of the series. The normal cooling curve and upper curve of heat generation shown in fig. 2 are taken from that paper.
Page 107 - specimen B of the Hadfield nickel-chromium steel after it,s third quenching, described above. In . conducting these experiments, an electric furnace was employed for heating, instead of the less convenient gas furnace formerly used, and the latest form of “ scleroscope “ for testing hardness was installed, also a most
