Page 219 - G is the galvanometer ; ww, are the wires along the banks, connected with copper plates,/, g, h, i, which are placed in the water. When this arrangement is complete, the electricity, generated by the battery, passes from the positive pole, p, to the plate h, across the river through the water to plate i, and thence around the coil of the galvanometer to plate /, across the river again to plate g, and thence to the other pole of the battery, N.

Page 258 - I would here state, that although the manures made in carrying out this invention will have Various matters combined with the alkaline carbonates, no claim of invention is made thereto separately, and such materials will be varied according to the matters which the land to be manured requires to have returned to it, in addition to the mineral substances above mentioned. The quantity of carbonate or phosphate of lime, used with carbonate of soda or potash, may be varied according to the degree of...
Page 219 - As the result of these experiments, it would seem that there may be situations in which the arrangements I have made for passing electricity across the rivers may be useful, although experience alone can determine whether lofty spars, on which the wires may be suspended, erected in the rivers, may not be deemed the most practical. The experiments made were but for a short distance ; in which, however, the principle was fully proved to be correct. It has been applied, under the direction of my able...
Page 258 - Germany) is to prepare manure in such a manner as to restore to the land the mineral elements taken away by the crop, which has been grown thereon and removed, and at the same time render the alkaline matters, used in making the manure, less soluble, so that they may not be washed away from the other ingredients, by the rain falling on the land. The improvements consist in combining carbonate of soda, or carbonate of potash, or both, with carbonate of lime, and combining carbonate of soda and carbonate...
