We are told that some brewers have now acquired such faith in refrigerators, as to think that they may dispense with coolers almost entirely. We strongly fear, however, that before the end of the first summer, they will have reason to repent of this over confidence, and lose more by the deterioration of their beer than the first cost of new coolers.—See article on Refrigerators.

A great deal of attention has lately been bestowed in the brewery, upon various mechanical arrangements, for the purpose of saving labour, &c.; but many of these changes seem to have been adopted, without any regard to their probable consequences.

Were our brewers, however, as has been already observed, to devote a little more attention to chemistry, they would soon discover, that,
