Exchange Extraordinary/' 



During the past few years my cabinets have been practically, empty. I now desire to 

 fill them up— not only with a private collection, but with a series of duplicates to use f(ir 

 exchange and other purposes— in fact I've got the Ooloi^ical "fever" once more and that too 

 in its most virulent type. Hence f want at once oolugical specimens of species both rare 

 and common, md I will during August or until Sept. 1st accept in exchange any species in 

 any quantity from any reliable collector on the following terms, viz: For the first set with 

 data of each species any collector may send I will allow full rates. Single eggs accepted at 

 one-fourth rates only. Our new "Standard Catalogue"' must be the one used in pricing all 

 specimens sent. All specimens must be blown through one smoothly drilled hole in the 

 side, and the contents must be thoroughly cleaned out. No end blown or second class 

 specimens accepted at any price. So exrhancie les* than S3. 00 can be hothered with. All pack- 

 ages must be sent prepaid at senders risk by mail or express. I shall neither repeat nor ex- 

 tend this "extraordinary" offer and I cannot spare the time to correspond in relation to the 

 same. Simply send on your specimens and state your wants and unless otherwise men- 

 tioned I will ship the same to you prepaid at my earliest possible opportunity and aunrnvtee 

 satisfaction. In return for your specimens you make your own selection frorn the following, 

 at prices quoted:
