Excerpt from A Catalogue of Physical Instruments: Catalogue 17
Under each subject we have aimed to include only those pieces best suited for the particular experiment and demonstration. In making this selection from our complete line we have found that it requires even greate... r judgment to determine what to omit than it does to determine what to include, but unnecessary duplication has been carefully avoided. We realize that the instructor whose duty it is to equip or improve a laboratory should buy only the best and at the same time strive to make his appropriation go as far as possible.
A large proportion of the articles offered have been designed and developed in our own laboratory under the supervision of men whose training and experience have well fitted them for the task. In addition we have made a careful selection from the best scientific establishments of the world. In making the selection we have been guided by numerous suggestions received from our customers, an obligation which we are pleased to acknowledge at this time, with the hope that all of our customers will feel it an obligation as well as a pleasure to favor us with any further suggestions which their experience develops.
