OUR attention is directed to the extracts 
from many letters received testifying to 
the value of “The Conchologists’ Ex- 
change,” which we have published in this 
number. Our circulation is slowly but surely 
extending to all foreign countries, which will 
bring our readers eventually into communica- 
tion with collectors located in all the desirable | 
collecting grounds of the world. 
It remains | 
for you to use this paper, not only for the pur- 
pose of advertising duplicates, but also as a 
medium for recording your own discoveries, 
for be they ever so humble, they will be ac- 
ceptable so long as they reach our require- 
ments; 1. e. Exactness and Originality. 
AVE you duplicates for exchange? If 
H so, do not wait for them to accumulate 
but advertise them in ‘The Con- 
chologists’ Exchange.”’ One of our sub- 
scribers added nearly four hundred species 
to his cabinet through one advertisement cost- 
ing him ¢ez cents. What a rate of interest on 
the investment is this! Others succeeded as 
well and even better in the exchange of books, 
scientific instruments, fossils, &c., to all of 
which our columns are open.
