Side 6 - Dixon, HH, and Atkins, WRG, Osmotic Pressures in Plants. I. Methods of Extracting Sap from Plant Organs, Sci. Proc. Roy. Dublin Soc. (ns) 13 : 422-433 (1913).
Side ii - Academy prefix to their transactions an advertisement, intimating that " as a body they are not answerable for any opinion, representation of facts, or train of reasoning, which may appear in the papers. The authors of the several essays are alone responsible for their contents.
Side 178 - Re. 1. Vol. V, No. III. The Varieties of Soy Beans found in Bengal, Bihar and Orissa and their Commercial Possibilities, by EJ WOODHOUSE, MA, FLS ; and CS TAYLOR, BA Price, Rs. 2. Vol. V, No. IV. On Phytophthora parasitica nov. spec. A new Disease of the Castor Oil Plant, by JF DASTUR, B.SC.
Side 387 - A Quantitative Examination of the Elements of the Wood of Trees in relation to the Supposed Function of the Cells in the Ascent of Sap.
Side 373 - Pressed from leaf -cells treated with liquid air, 1-207° 0-646° 0-661° 14-52 1341 377 of carbohydrates passing up through the tracheae in the transpiration stream has about the same freezing-point as a 0'25 per cent, solution of glucose, or a 0'50 per cent, solution of sucrose. The concentrations of the carbohydrates of the root approximated to those of 0-3 per cent, solution of glucose, or of 0'7 per cent, of sucrose. These observations strikingly negative Sachs' view that the stream rising from...
Side 153 - Dixon, HH and Atkins, WRG On osmotic pressure in plants; and on a thermo.electric method of determining freezing points.
Side 195 - Plants affected with this fungus exhibit symptoms of disease in their subaerial organs -which are of the wilt type. On account of this character he suggests that the disease be known as pink rot wilt. The disease is considered contracted from the soil and is of serious consequence only in land which...
Side 8 - A being the depression of freezing-point, P the osmotic pressure in atmospheres calculated from A, and c the specific electrical conductivity at 0°. TABLE I. From the above figures it may be seen that, both in osmotic pressure and electrical conductivity, pressed yeast gives values which are much higher than those of wort. Baker's yeast, however, gives a low osmotic pressure, but a high conductivity even after washing. The figures afforded by the sap of yeast and by the surrounding nutritive fluid...
Side 10 - Suooinic acid, for instance, and its more highly ionised ammonium salt have been shown by Ehrlich (4) to arise during fermentation from glutamic acid. To avoid the possibility of error in the comparison of yeast-juice and beer owing to the expulsion of gases by freezing the former solid, measurements were made of both freezing-point and conductivity of beer as separated from yeast and after freezing solid. No appreciable difference was observed between the two sets of figures. BIBLIOGRAPHY. 1. DIXON,...
Side 214 - The Subsidence of Torsional Oscillations in Nickel Wires when subjected to the Influence of alternating Magnetic Fields.
