From a letter, written under date of December 25th, 1903, we quote the following: 

 " I wish to state that the Bausch & Lomb microscope which I purchased from you a 

 year ago last August, and the eye-pieces and objectives, have all proved very satis- 

 factory indeed, and though second-hand when purchased, I find them as good as new 

 on testing them." 



I have many other customers who have heartily shown themselves as equally well 

 pleased. 



Contained in my Special Bulletin above referred to are Cameras, Photographic 

 and Microscopic Lenses, etc.
