heat, etc.), the Bibliography of Physics, and National Laboratories. The final programme is, however, still to be settled. The subscription for membership is twenty francs, or four dollars. The foreign secretary of the congress is M. Charles Edouard Guillaume, Pavilion de Breteuil, Sevres (Seine et Oise), Paris.
In a book called Literary Munich Portraits, with brief biographical sketches by Paul Heyse, are given of twenty-five of the most prominent literary men of that brilliant capital. Only two authors not Germans are included. One of them is our contributor, E. P. Evans. The other is the Norwegian novelist Bjornson. Heyse leaves himself out, although he is the greatest literary character of them all.
Some recent experiments, conducted jointly by the Kew Observatory Committee and the International Bureau of Weights and Measures at Sèvres, were made to compare the platinum thermometer of Professor Callendar, which measures temperature by the varying resistance of a platinum wire, and the older mercury and gas thermometers. It was found that below 100° C. the differences between the observed values on the nitrogen scale and those deduced from the platinum thermometer are exceedingly small, and that even at the highest temperature (590°) the differences only amount to a few tenths of a degree.
The American Chemical Society has gained 232 members during the past year, making the present number 1,540. The report of the committee on the analysis of coal, submitted to the recent meeting of the society at Columbus, Ohio, embodied detailed instructions in regard to the best methods of analyzing coke, and outlined a plan for securing uniformity in such analysis by chemists throughout the land. This report was adopted.
At the recent annual meeting of the American Society for the Promotion of Agricultural Science Prof. W. J. Beal reported concerning the germination of seeds, after long keeping, that experiments had been tried with various seeds five, ten, fifteen, and twenty years old, from which it appeared that seeds of a large number of important plants would germinate after fifteen years, but the number sprouting after twenty years was small.
A paper was read by Dr. L. O. Howard, at the recent meeting of the American Society of Entomologists, recording the success which has been obtained by the fig-raisers of California in fertilizing the Smyrna variety of figs by the aid of the blastophaga which issues from the Capri figs covered with their pollen. A generation of the blastophaga has been developed at Fresno by which many Sniyrna figs have been satisfactorily fertilized, and there is considerable probability that the insect has at last established itself on California soil.
The five hundredth anniversary of the birth of Gutenberg, associated with the invention of printing, is to be celebrated at Mayence, June 24, 1900. It is hoped that the foundation of a Gutenberg Museum may be a result of this movement. An exhibition illustrating the art and progress of printing is also expected to be held.
The conclusion is drawn by the Italian, Signor Albini, from investigations on the nutritive value of whole-meal bread, that it is inferior to that of ordinary white bread, and that a further disadvantage comes from the excessive quantity of indigestible matter, formed of the harder parts of the pericarp of the grain, which it contains.
