THE SUBSTITUTE. 
as 
ins-ects in tlieir native conntries: 
indeed a good deal, considering 
ilie difficuliies attendant, has 
already been accomplished ; and 
we hope when the collectors, whose 
enihusiastic ardour has for years 
sustained (hern in the cause of 
Science in the midst of fever, 
death and desolation, shall give 
the result of their experience to 
the world, that Science, as well as 
the individuals, may be enriched 
in proportion to the danger in- 
curred in the acquisition. May it 
not be taken amiss if we remind 
those who would not see such servi- 
ces left to be their own reward, that 
they could not better show their 
appreciation of them than by con- 
tributing their share of the ex- 
pense noiv, or it may happen that 
for want of support the supply 
of novelties and rarities may 
be stopped, and the means of 
getting them not again occur. 
It should be a rebuke to our 
English collectors to know that 
rare insects from the ends of the 
earth are sold at less prices than 
British ones. So much for indi- 
viduals. Public museums should 
be in a position to do more in pro- 
curing novelties; but, with scarcely 
an exception, museums are not uj) 
to the mark in this any more 
than in other respects, though 
whether the fault be that of their 
conductors or supporters it is net 
now our purpose to discuss.
