VIII THE OOLOGIST 



EGG COLLECTORS! 

 ATTENTION!! 



EXCHANGE OFFER EXTRAORDINARY!!! 



Having certain series in my collection that I desire to fill out and com- 

 plete at an early day that I may give more attention to others, I have decided 

 to make you the following unprecedented proposition: 



For all the specimens of vi^hich I want One set mentioned below, I will allow 

 you in exchange twice their value as given in Lattin's 1905 Price List. For 

 those of which I want two sets, I will allow one and two-thirds times the Lattin 

 prices. For those of which I want three sets I will allow one and one-half 

 times; and for those of which I want four sets, one and one-third Lattin's prices. 

 In all cases where you can furnish all of any one species desired by me, I will 

 allow the full double value. All specimens on both sides to be first class and 

 subject to return if unsatisfactory. 



When you remember that very many of the specimens wanted are of com- 

 mon species and that I have without doubt the largest and most varied exchange 

 list in America for you to select from, I am sure you will see that this is an 

 opportunity never before offered for you to enlarge your collection. 



In your Spring collecting lay aside those listed for me, and send me a list 

 of what you have, and later in the season I am sure an exchange can be 

 arranged to your advantage and satisfaction.
