The Same Backward Movement
Being Continued, The Spine, By The Full Action Of The
Muscles, Was Bent Like A Spring;
And the insect at this moment
rested on the extremity of its head and wing-cases.
The effort being suddenly
Relaxed, the head and thorax flew
up, and in consequence, the base of the wing-cases struck
the supporting surface with such force, that the insect by
the reaction was jerked upwards to the height of one or
two inches. The projecting points of the thorax, and the
sheath of the spine, served to steady the whole body during
the spring. In the descriptions which I have read, sufficient
stress does not appear to have been laid on the elasticity of
the spine: so sudden a spring could not be the result of simple
muscular contraction, without the aid of some mechanical
contrivance.
On several occasions I enjoyed some short but most pleasant
excursions in the neighbouring country. One day I went
to the Botanic Garden, where many plants, well known for
their great utility, might be seen growing. The leaves of the
camphor, pepper, cinnamon, and clove trees were delightfully
aromatic; and the bread-fruit, the jaca, and the mango,
vied with each other in the magnificence of their foliage.
The landscape in the neighbourhood of Bahia almost takes
its character from the two latter trees. Before seeing them,
I had no idea that any trees could cast so black a shade on
the ground. Both of them bear to the evergreen vegetation
of these climates the same kind of relation which laurels
and hollies in England do to the lighter green of the deciduous
trees.
