152 IMPORTANT NEW WORKS ON ENTOMOLOGY. 
Another point on which the deficiency of our printed 
information respecting British Butterflies is very striking, 
is their geographical distribution. All the old localities are 
carefully brought forward here, though many of them have 
been long deserted by the respective species; and, on the 
other hand, localities where species not of general occur¬

list of the Butterflies occurring in his own locality, noting 
their times of appearance, and any peculiarity of habit, and, 
where possible, the food-plant and habit of the larva! At 
small trouble to each individual, an idea of the distribution 
of each species might be satisfactorily obtained, and increased 
stimulus given to the study of the British Butter flies .—Editor

u Without steady application a long course of study cannot 
be mastered, and nothing is more certain than that habitual 
diligence brings other virtues in its train; for instance, tem¬ 
perance and self-control, to say nothing of punctuality and 
accuracy—yet even these latter have a real connection with 
truth and honesty.”— Rev . Charles Graves , DD. 
u Any one who looks around him will, I think, see that 
the public mind is now educating itself, rather according to 
a scientific than a literary type, and that the great element 
in the social progress which is going on around us is not 
literature but science.” 
“ I have called to mind the names of six men in London 
who, by their labours for the advancement of science, have, 
it appears to me, exercised a greater influence on the popular
