The supply of numbers one and two of this Journal remain- 

 ing in the hands of the publishers has become reduced below 

 the limit they desire to preserve for binding and for special pur- 

 poses, and they would esteem it a great favor on the part of 

 those who may have received duplicates, as sample copies or by 

 the accidents of mailing while the lists were imperfect, if they 

 would return such duplicates to them. They will gladly return 

 the postage if the address of the sender is placed on the 

 wrapper.
