[9] "Nous n'avons pas ete moins saisis d'etonnement a la vue
de l'innombrable quantite de pierres de touts grandeurs,
bouleversees les unes sur les autres, et cependent rangees,
comme si elles avoient ete amoncelees negligemment pour remplir
des ravins. On ne se lassoit pas d'admirer les effets
prodigieux de la nature." -- Pernety, p. 526.

[10] An inhabitant of Mendoza, and hence well capable of
judging, assured me that, during the several years he had
resided on these islands, he had never felt the slightest
shock of an earthquake.

[11] I was surprised to find, on counting the eggs of a large
white Doris (this sea-slug was three and a half inches long),
how extraordinarily numerous they were. From two to five eggs
(each three-thousandths of an inch in diameter) were contained
in spherical little case. These were arranged two deep in
transverse rows forming a ribbon. The ribbon adhered by its
edge to the rock in an oval spire. One which I found, measured
nearly twenty inches in length and half in breadth. By counting
how many balls were contained in a tenth of an inch in the
row, and how many rows in an equal length of the ribbon, on
the most moderate computation there were six hundred thousand
eggs. Yet this Doris was certainly not very common; although
I was often searching under the stones, I saw only seven
individuals. No fallacy is more common with naturalists,
than that the numbers of an individual species depend on
its powers of propagation.
