in-breeding and out-crossing is fully considered, and though the

Notice. —It is with regret, but it is upon compulsion that we 
do it, that we once more call attention to the fact that many , very 
many , of our subscribers have failed to remit their dues. Some 
are delinquents of one, some of two, a few of three, and some 
of even four years’ standing. Though it was never our expecta¬ 
tion to find in the Review a source of wealth to its proprietor, it 
was never his calculation to suffer its publication to involve him 
in debt. This may be considered as a last reminder to our non¬ 
paying readers of their indebtedness. Their dues must be paid, 
or their names will disappear from our mail-book. The postal 
that we have sent lately was to enable us to correct our list of 
subscribers and do away with the irregular delivery as much as 
possible.
