phials filled with alcohol. I enter into these details, because,
though little interesting in themselves, they serve to show that we
had no means of bringing back, in their natural state, many objects
of zoology and comparative anatomy, of which we have published
descriptions and drawings. Notwithstanding some obstacles, and the
expense occasioned by the carriage of these articles, I had reason
to applaud the resolution I had taken before my departure, of
sending to Europe the duplicates only of the productions we
collected. I cannot too often repeat, that when the seas are
infested with privateers, a traveller can be sure only of the
objects in his own possession. A very few of the duplicates, which
we shipped for Europe during our abode in America, were saved; the
greater part fell into the hands of persons who feel no interest
for science. When a ship is condemned in a foreign port, boxes
containing only dried plants or stones, instead of being sent to
the scientific men to whom they are addressed, are put aside and
forgotten. Some of our geological collections taken in the Pacific
were, however, more fortunate. We were indebted for their
preservation to the generous activity of Sir Joseph Banks,
President of the Royal Society of London, who, amidst the political
agitations of Europe, unceasingly laboured to strengthen the bonds
of union between scientific men of all nations.

In our investigations we have considered each phenomenon under
different aspects, and classed our remarks according to the
relations they bear to each other. To afford an idea of the method
we have followed, I will here add a succinct enumeration of the
materials with which we were furnished for describing the volcanoes
of Antisana and Pichincha, as well as that of Jorullo: the latter,
during the night of the 20th of September, 1759, rose from the
