 This is the first of a series of catalogs to be issued by us, representing 

 the complete service we are now prepared to render the laboratory 

 worker. The purpose back of it is indicated by the following extract 

 from its preface : 



"The founders of our organization were originally research chemists. 

 As such they have themselves felt the need in the past of a closer ap- 

 preciation by apparatus houses of the equipment problems of the modern 

 laboratory. To satisfy this need is our present aim. And we feel that 

 our earlier experience peculiarly quaUfies us to give a service of practical 

 benefit to all laboratories with which we may enjoy business relations." 

 This experience is further supported by that of the Chemical Depart- 

 ment of the Bausch & Lomb Optical Company, whose complete stock of 

 supplies we purchased on Janua y 1st of this year, acquiring at the same 

 time the personnel of their long-established organization in that depart- 

 ment.
