TITLE:
Report on the contents of a bottle of water from Col<o>n, Panam<a>
ABSTRACT:
When received from our colleague Dr. Str<o>mfelt, of the Popay<a>n
Museum in Le<o>n, the water (H{-2}O) of a bottle retrieved at sea
gave out an excessively disagreeable odor of putrefying organic matter,
and ammonia (NH{-3}) was given off in considerable quantities, as was shown
by holding a rod moistened with hydrochloric acid (HCl) over the mouth
of the bottle. Inside was discovered a greenish-colored, slimy deposit,
microscopic examination of which revealed a large quantity of eggs of some
animal, and the decomposed remains of a fish. Evidence will be presented
to show that the main content of the slimy mass originated from eggs deposited
by a frog, most probably {iAtelopus varius}, and that the fish, a poeciliid
of the genus {iPriapichthys} Regan, died while attempting to eat the fetid
remains.
