PERSONAL. 



On account of the increase of my 

 business during the last five years, I 

 have decided to form a company in 

 conjunction with Mr. John B. Garnett, 

 Pharmaceutical Chemist, and others, 

 and we have taken premises situated at 



48 Deansgate, Manchester, in the 



centre of the City, to which address 

 all communications should be sent in 

 future. This arrangement will give 

 me greater facilities to attend to the 

 preparation of Microscopical and 

 Lantern Slides personally. 



We shall keep a stock of all my 

 varied preparations at 48 Deansgate, 

 together with types of the best Micro- 

 scopes, Lanterns, Cameras, &c, by the 

 leading Makers. We shall also supply 

 Microscopical Stains, Re-agents, Slips, 

 Cover-Glasses, &c, &c, Photographic 

 Plates, Papers, and Chemicals, <2fc. ; 

 as well as tindertake the Developing 

 of Custoiners Negatives, and making
