Página 111 - When cut grass was given alone the result was very unsatisfactory ; but when oilcake was given in addition the amount of increase upon a given weight of animal within a given time, and for a given amount of dry substance of food consumed, was not far short of the average result obtained when oxen are fed under cover on a good mixed diet.

On treating some pure indigo-blue with alcohol, to which an alkaline solution of protoxide of tin was added until it dissolved, then adding acetate of soda and digesting at a moderate heat, the indigo-blue after some time ceased to be deposited on exposure to the air, or even agitation ; it had entirely disappeared. The same thing occurred when formiate of soda was employed in the place of acetate. It was evident, therefore,...

They might be considered as conjugated compounds — compounds of which organic chemistry affords so many examples; and it might consequently be possible to obtain from them, by decomposition, some of the simpler bodies which are known to have entered into their composition. 1 have, however, been unable to discover any facts in favour of this view. Neither...

For Scotland, and for Ireland, it was only possible to found an estimate...
