TO OUR CUSTOMERS 



In bringing out this war edition of our Chemical, Industrial and Bacteriological Catalog we wish 

 to call the attention of those into whose hands it comes to certain features which we believe are worthy 

 of careful attention. AMERICAN MACE APPARATUS. 



We have eliminated from this catalog all apparatus which was formerly imported and has not been 

 duplicated up to this time in this country. This is the first and only truly American catalog of chemical 

 laboratory supplies published which pretends to be at all complete. The only important item of foreign 

 manufacture listed is Whatman English Filter Paper, a line which baa won the support of all chemists, 

 and for which no American substitute has as yet been introduced. 



UP-TO-DATE APPARATUS. 



We have selected only up-to-date types of apparatus, leaving out any forms which appear from our 

 experience to be classical relies. PROMPT DELIVERIES. 



We have Included only apparatus which we know is being manufactured at this time, and can be 

 delivered within a reasonable length of time. We can not, of course, predict the effect which the de- 

 mands of the war may have upon the discontinuance of any manufactured articles, nor the effect of 

 the demands of Government laboratories upon the adequacy of the supply. We are endeavoring to keep 

 a large stock and every square foot of available space in the 2^4 acres of our 6 story building is packed 

 to the roof with reserve stock. GLASSWARE AND PORCELAIN. 



Our stocks of glassware and porcelain have beeu selected from the American market after 3M> years 

 of careful observation, experiment and comparison of data from various sources. We believe them to be 

 the best adapted to the needs of American laboratories. We propose to change brands only after we 

 have been convinced that such a change best serves the needs of the chemical trade. 



PRICES. 



The prices in this catalog were current at the time of publication. Owing to the rapid changes in 

 the cost of raw materials and of labor, we cannot guarantee prices to remain constant for any length of 

 time. We shall be glad to fill orders at prices current at the time of their receipt. If necessary to have 

 the exact cost of materials, we urge our customers to send in their lists for quotation. 



ORDERS AND LISTS FOR QUOTATION. 



1. When possible, specify our catalog number, name of article and dimensions. Further specifica- 

 tion is not necessary. We furnish conveniently ruled order sheets upon request. 



Note: Lists made from catalogs of other dealers will be transposed by us into our own numbers 

 when possible, with our guarantee that the articles will equal in efficiency and finish those originally 

 specified. 



2. Specify date when shipment is desired, with route and method of shipment, i. e., parcel post, 

 express or freight. BOXING. 



No Charge for Boxing and Cartage except on orders of $10.00 or less; then a nominal charge will be 

 made if the boxing exceeds five per cent of the value of the shipment. Prices are F. O. B. Chicago, 

 unless otherwise specified. TERMS. 



Terms are net, thirty days after delivery. Orders from parties unknown to us should be accom- 

 panied by remittance or by satisfactory business references. 



Note: Unless otherwise directed, invoices and statements will be mailed to the person placing 

 the order, upon whom we relv to O. K. the Bills Promptly and thus Expedite Payment 



REMITTANCES. 



Remittances should be in exchange at par in Chicago, as we are obliged to pay exchange upon all 

 private checks, except from a few of the largest cities. 



SHIPMENTS. 



Unless otherwise ordered, shipments are made by us At Once, by such routes as will insure earliest 

 delivery. Large shipments are made by freight and smaller shipments by express or parcel post, as 

 seems expedient to us. CLAIMS FOR BREAKAGE. 



We employ only experienced packers and guarantee our goods to be in first class condition when 

 delivered to the carrier. Our responsibility ceases at that point, and all claims for damage or breakage 

 must be made upon the carrier responsible for their safe delivery. We shall be glad to aid in any way 

 possible in the prosecution of such claims and the recovery of damages. 



ORIGINAL CASES. 



We especially recommend that our customers take advantage of quantity purchases. American 

 manufacturers of glassware and porcelain have made it possible to secure these commodities in original 

 case lots at wholesale prices. RETURNED GOODS. 



In order to avoid the delays incident to the identification of returned goods, we respectfully insist 

 that no articles be sent in without first notifying us as to the reason for their return and the disposition 

 to be made of them. Frequently adjustments can be made without the necessity of returning the goods. 

 If after consideration it appears necessary that the goods be returned, we shall send suitable shipping 

 tags which will insure prompt attention upon their receipt. 



NOTICE TO THE TRADE. 



Special notice is given to the trade that this catalog is copyrighted, and that unauthorized repro- 

 duction of new cuts or illustrations therefrom constitutes actionable infringement of our rights. We 

 shall use every legal means to protect our work and property.
