local prejudices. As the travelled cuckoo was the first to conceive the 
low j earned in the south, where air and prospect and 
Space are best appreciated, to adopt the verandah principle, there so 
universal. Both bees and birds have now been shown to have made 
great strides in architectural knowledge." ‘‘London Spectator,” April 16, 
1870, in a communication from ** Pouchet” in the ** Pall Mall Gazette.” 
A parallel instance in bees is noticed by Dr. Ogle in a very important 
article on the ** Fertilization of Various Flowers by — contributed 
to the April number of the * Popular Science Review." The arrangements 
for the cross-fertilization of the flowers of the bean and other papilion- 
aceous plants by bees, here described by Dr. Ogle, are pretty well known, 
o the fact that both humble and hive bees have the trick of evading 
iut duty by piercing a hole in the side of the calyx of bean-tlowers, so 
getting at the nectar by a short cut. Dr. Ogle has remarked that while 
cession of bean flowers, uniformly does either the one or the other. It 
ence; so ng slow in acquiring knowledge, others quicker. Th 
Scarlet Runner, when the bloom is covered with gauze to keep insects, 
is wholly sterile; and so indeed habitually are à good man un- 
covered blossoms. The latter is probably owing to the observed fact 
that most bees have learned to get at the nectary by nipping the tube. 
Were all bees equally clever there would be an end of scarlet runners, 
unless indeed either nature or artifice were to induce some modifica- 
tion of structure by which the tube might be protected and the bees 
again driven to the mouth." We think it proper to add that Dr. Ogle's 
press, showing that the proofs have not been revised by the author nor 
by any competent proof reader.
