Animal Concretions
Concretions of various kinds are occasionally found in the brain,
lungs, heart, liver, kidneys, gall-bladder, intestines, and urinary
bladder. The stomachs of many animals afford concretions of different
kinds, particularly those known under the name of Bezoar Stones; and
travellers inform us that stones are met with in the eggs of the ostrich.
All of these bodies are interesting and valuable to the natural historian.
Skeletons
Collectors ought not to neglect to preserve the skeletons of the
different species of animals. The best way of cleaning bones, is to expose them to the air, and allow
the insects to eat off the flesh. This being done, they ought to be
washed with sea water, and afterwards freely exposed to the sun. The
best skulls are obtained by putting the whole head in rum or whisky, or
a strong solutions of alum; and both male and female heads ought if possible
to be preserved.
