Стр. 202 - Housekeepers, or the Art of Preserving All Kinds of Animal and Vegetable Substances for Several Years.
Стр. 187 - By the deficiency or absence of one necessary constituent, all the others being present, the soil is rendered barren for all those crops to the life of which that one constituent is indispensable.
Стр. 62 - ... the sick room. In fine, this article makes paps, custards, puddings, and cakes, equal to the best milk ; and one may be sure it is an unadulterated article, obtained from well-pastured cattle, and not the produce of distillery slops ; neither can it be watered. For our steamships, our packets, for those travelling by land or by sea, for hotel purposes, or use in private families, for young or old, we recommend it cordially as a substitute for fresh milk.
Стр. 168 - To the conclusions already stated, the author adds that there are periods to be selected for the employment of ammonia during which this gas produces different effects. If we commence its use when several months intervene before the flowering season of the plants, it produces no disturbance ; they follow the ordinary course of vegetation.
Стр. 193 - The advantages obtained by this method of making hay, or rather of preserving grass in a dry state, are sufficiently obvious. By this means all the constituents of the grass are retained in a state of integrity ; the sugar, by the absence of water, is protected from undergoing decomposition, the...

Стр. 254 - ... masses, weighing each from a few grains to several ounces. These soon bleach and whiten upon exposure to the light of the sun, finally becoming nearly colorless, semitransparent, and often filled with minute fissures. Specimens collected from the trunks of the trees were generally found to be less pure and more highly colored than when obtained from the branches. The gum may be collected during the months of July, August, and September ; but the most favorable period for that purpose is in the...
Стр. 199 - Mutton .... 2-96 23'38 Veal 2-87 22'67 The last table shows that the true order should be beef, chicken, pork, mutton, and veal, a result which experience confirms. It may, however, be remarked, that there is considerable difference between the same kind of meat derived from different animals ; and that the same amount of two different kinds of beef broth, both containing the same amount of water, may have very different nutritive values.
Стр. 167 - Is the nitrogen of the air absorbed by plants? Third. Influence on vegetation of ammonia added to the air. 1. The author remarks, that since the observation of M. Theodore de Saussure, that the air is mixed with ammoniacal...
