The fluid malt extracts which now reach us from Germany have become less trustworthy than they formerly were.

Some of them keep badly, and are uncertain in composition, one bottle being good, another bad.

The more constant, and at the same time most agreeable, extracts are those now made in this country.

Although their diastasic powers are usually less than is claimed for them, and vary greatly even in the best makes, they so far have seemed to me on the whole more satisfactory than the imported malts.

It is very desirable that a thorough chemical study should be made of the various malt extracts, solid and liquid.
