We have elected to prepare a' fairly complete catalog of convenient size, rather than an encyclopedia of scientific apparatus, which would of necessity be so bulky as to be unwieldy.

In the selection and arrangement of descriptive data and illustrations, we have been guided by the requirements of those who may have occasion to use the catalog. We have made an attempt to simplify the work of ordering our merchandise, wherever it has been possible to do so, without sacrificing accuracy or necessary information.

Each illustration shows either a standard type of apparatus or a characteristic feature which may be adapted to your requirements.
