leading from La Brele to Lyons, at the distance of about four miles, the strata of grey
(or kind of sand-stone), which are in many parts abruptly filled with different sorts of
shells, confusedly mixed together, viz. tellimites, municites, pinnitcs, and other fragments
of similar fossils.
Tliese strata appear to be of a coarse grain, mostly soft, so as to crumble with ease,
and incline to a greyish blue. The botanist may likewise find, in these environs, a profusion
of plants with which to decorate his herbal, and for which I refer him to the
Horlus Liigdimensis of Boerhaave.
Quitting, at last, this charming city, where, during my last visit, a short time before
the revolution, I had staid six weeks, in my way to Geneva, I directed my course
towards the Pennine Alps, leaving the bridge La Guillotiere, which leads to Savoy, on
my right, and passed through the gate of Ste. Claire, at the extremity of the Quay of the
Rhone*. But as the distance from Lyons to Geneva is not less than ninety miles,
mostly across a mountainous country, which makes it difficult to accomplish in one
day, and as speed would have defeated the purpose of my tour, I determined on
stopping at Nantua, a small town in the province of Bugey.
