The lowest weight of the bushel and the greatest amount of straw were obtained in that season which had the greatest number of rainy days and the lowest temperature ; the least amount of straw with the driest season, and the finest quality of grain in the hottest summer. On comparing the proportion of grain to straw and the weight per bushel of the corn obtained from the unmanured space, with the average results of the various experiments, it will be seen how much they agree one...
Page 321 - In 1847, we carefully took samples from a growing wheat crop at different stages of its progress, commencing on June 21, and in these samples the dry matter, the mineral matter, the nitrogen, &c., were determined.
Page 708 - Vandenbergh were elected Fellows of the Society. The following papers were read : — " On the Diurnal Variation of Wind and Weather in their relation to Isobaric lines,
Page 329 - Further, the seasons showing the highest amount of potash were of much higher maturing character than those showing the lowest amounts. Next, it is seen that there is still greater, indeed enormous, variation in the amount of potash in the dry substance of the straw with the same manure in different seasons. There is also great variation according to manure; comparatively little when there was full supply, but considerable without manure — that is, with exhaustion.
Page 321 - ... absorption of nitrogen occurs, some experiments may be quoted. Lawes and Gilbert" say: In 1884 we took samples of a growing wheat crop at different stages of its progress, commencing on June 21, and determind the dry matter, ash, and nitrogen in them. Calculation of the results showed that, while during little more than five weeks from June 21 there was comparatively little increase in the amount of nitrogen accumulated over a given area, more than half the total carbon of the crop was accumulated...

Thus, after a variable, but upon the whole, mild winter, the early spring was dry and cold, the remainder cold and wet, and the early summer cold and changeable, with little rain ; then came a short interval of fine and hot weather, succeeded about the ripening period by very heavy rains and prevailing low temperatures. The harvest period was much broken, generally wet and unfavourable,...

Those who study in the Polytechnics have a certain advantage in this particular, inasmuch as they can become acquainted with processes carried on in a variety of manufactures ; and what is wanted now-a-days is something like what would result from a fusion of the work of the Universities and the Polytechnics...
Page 3 - ... short time the solution ceases to give a starch reaction with iodine, but it is best to maintain the digestion for an hour, because filtration is then easier. At the end of that time the contents of the beaker are boiled for eight or ten minutes, thrown on to a filter, and the filtrate received into a 100 cc. measuring flask. The residue is carefully washed with small quantities of boiling water at a time. When the flask is nearly full, its contents are cooled down to 15°-5, and made up to 100...

Dr. Perkin, in his recent address before the Chemical society of England at its anniversary meeting, says, " If there is any value in chemical products as curative agents, if there is any value in physiological chemistry, or any importance in toxicology, surely medical students should have a sound knowledge of chemical science, and not simply learn to detect an acid and a base in a mixture,...
