forty-three feet more elevated than the Rhône, and nine hundred and forty-seven above
the Mediterranean sea.
Not far from thence, and within the inclosure of the garden des Pères Mùihnes,
remain the fragments of the Roman theatre noticed in the preceding description,
a sketch of which is given in plate XII. fig. 1. The greatest part of its circuit is still
extant.
Beyond the same convent, and near the gates St. Irenée, stands the noble aqueduct
already mentioned, which is s\ipposed to have extended ten miles. N" 2 exhibits a part
of those magnificent ruins, taken about a mile and a half from the town St. Irenée.
Tlie famous monastery of the Chartreux is built on the summit of a mountain
directly opposite to de Fourvière, which tends rather more to the east, and serves as a
kind of separation between the Rhone and the Saone.
From this elevation the prospect is nearly as extensive as from the former; for the
eye not only wanders over the rich and fertile plains of Dauphiny and La Bresse, but
likewise takes in the greatest part of the course of those beautiful rivers.
In descending the same mountain, almost contiguous to La Croix Rousse, stand
the vestiges of a Roman Naumachia, deserving notice ; the whole of its external circuit,
which is oval, being entire.
I think I may venture to assert, that amateurs in painting and architecture may be
as amply gratified in visiting the noble edifices which exist in such profusion both
within and without the city, as the naturalist and botanist by exploring its environs.
But as I do not mean to enlarge on this subject at present, I shall merely add, that the
formation or structure of the mountains de Fourvière and Chartreux are worthy of
attention.
These mountains, which are in general calcareous, exhibit, in many places, enormous
pieces of granite, which appear as if emerging from beneath their strata j
whereas, in other parts, such pieces of granitic stone lie scattered on their northern
sides, resembling, in that respect, the long chain of hills near Turin, described in the
author's " Maritime Alps," page 15.
I have likewise remarked, on the continuation of the mountain de Fourvière (the
side toAvards St. Eliame en Forêt), that its calcareous strata incline considerably under
hills of schisti, of which the lamina: are neariy vertical, containing a quantity of curious
impressions of plants and marine substances. And again, in a hollow or cross-road
