E. W. desires to call attention to the fact that " Brown Cement " is his 

 original discovery, and was first referred to in a paper read before the 

 Manchester Science Association, on Jan. 26, 1880. Its success has been 

 so great that the name has been copied, and numerous imitations have 

 been advertised and sold ; but Microscopists, when purchasing at a 

 dealer's, should insist on having the original cement, which at present 

 is unsurpassed. Every Requisite for Micro. Work.
