CHROMIC ACID AS AN ESCHAROTIC.

PUBLIC HYGEINE.

CHEMICAL TECHNOLOGY;

Knapp’s Technology belongs to a class of books char­ac­ter­is­tic of the present day, and of the highest and most extended usefulness. Giving the practical details of the arts in connection with the scientific principles on which they are founded, it extends the views of the manufacturer and the economist, and places him on the right path for further improvement. To the American it presents the further advantage of ample and precise details of what is being done in Great Britain and on the Continent of Europe. All engaged in pursuits with which chemistry has any connection (and with what is it not now connected?) will find in the various volumes of the Technology, valuable information in regard to their own peculiar avocations, while the variety of its information and the copiousness of its illustrations, gives it a high interest to the general reader.
