THE editor and publisher of one of our exchanges is also engaged 

 in running a second-hand apparatus store. It is interesting 

 to read the prices attached to these old goods, for which "the pub- 

 lisher does not hold himself responsible * ^ *." 



The person wishing to sell must pay ten cents per line for each 

 insertion, and a commission of ten per cent, on all sales. 



But the buyer! 



So far as we know we can sell any of the goods offered in said 

 published list, and warranted direct from the manufacturers for the 

 same price as offered by said publisher for second-hand goods. 



For instance a ys in. Beck is offered at ^16.00. We will dupli- 

 cate it NEW for $16.00. 



A ^ inch Beck, immersion adj., is offered at $40. We will 

 duplicate it NEW for $40. 



An erector of Zentmayer's, for $5.00. We will furnish NEW 

 for $5.00. 



A 3 inch "Spencer" is offered for $4.80. We will duplicate it 

 NEW for $4.80.- 



A j4 inch of Bausch and Lomb is offered at $7.00. We will 

 duplicate it NEW for $7.00. 



We do not desire to go into this business, but if any of our 

 friends desire NEW goods at the same price that second-handed 

 ones are offered we will accommodate them so far as indicated 

 above. 



We will also hold ourselves responsible for the goods as repre- 

 sented.
