3 Sir Everard Home’s farther observations 
In the locusta varia, whose feet have four joints, under the 
first are two very small globular cushions, and two large 
oval ones ; under the second, a corresponding pair of oval 
ones ; and under the third, a pair of cushions different from 
the others, in being much larger, globular, and semi-trans- 
parent ; there is no sucker between the claws, and this insect 
has no power of supporting itself against gravity. 
As the flea has powers of jumping not exceeded by any 
other insect, it was natural to expect a similar apparatus under 
its feet ; but as no such cushions are met with, we must con- 
elude that the lightness of its body rendered them unne- 
cessary. 
EXPLANATION OF THE PLATES. 
Plate XVII. < 
Represents six different views of the third toe of the fore 
foot of the lacerta gecko. 
Fig. 1. Is the upper surface of the toe, to show the manner 
in which it spreads laterally. 
Fig. 2. The under surface of the same toe, to show the 
orifices of the pockets or suckers. These two figures are 
magnified 100 times. 
Fig. 3. Two portions of two contiguous suckers, showing 
that the fringed termination is only continued from the ends 
of the alternate membranous partitions. The parts are magni- 
fied 2500 times. 
Fig. 4. A front view of a longitudinal section, to show the 
bones and muscles. 
Fig. 5. A side view of a longitudinal section. These two 
are magnified 100 times.
