Two years ago we realized that the scientists of the United States had in their possession NO 

 AMERICAN CATALOG of laboratory supplies. Nowhere had the fine hand of the German 

 Propaganda operated with more conspicuous success than in the field of scientific supplies. _ A glance 

 at any catalog that has been published in this country so far— including our own former editions— will 

 substantiate this statement. 



Realizing this severe handicap to American laboratories, the Central Scientific Company began 

 at once a careful and extensive investigation of manufacturers in this country, a thorough search of 

 all scientific literature for correct specifications of standard and new designs, the urging of reluctant 

 manufacturers to undertake new work, and the detail work of compiling, checking and editmg

We are glad to announce that, in spite of discouragements of all kinds, including the pressure 

 of war demands, the loss of valuable office assistants, the scarcity of raw materials and the fluctuations 

 of the markets, the task has been completed. 



We take pleasure in presenting to the scientists of America our new catalog, feeling that we have 

 rendered A NATIONAL SERVICE to the laboratories of our country. To them we offer our catalog 

 as our contribution in helping to forever free our scientists from the necessity of depending on 

 German made apparatus. 



OUR POLICY in the future is to handle and co-operate in the development of American 

 Made laboratory supplies. 



We have limited our first edition, preferring to place it only in the hands of those whose need 

 of an adequate list of laboratory supplies is most pressing. A later edition will be issued after the 

 more urgent and immediate need is supplied.
