The decadence of
Zephyria has nearly corresponded to this transference. The sulphurous
emanations no longer reach the place, their passage being blocked by
the mountain mass. Once more, on the west side of the marshy and
fever-infested plain of Catania, traversed by the Simeto, is a sulphur
mine, and beyond it, at a higher level, a village which was abandoned in
the early part of this century because of marsh fever. Yet there is
a colony of workmen living about the mine, and they seem to be
advantageously affected by the emanations. M. D'Abbadie further mentions
that the engineer who made a railway through this notorious plain
preserved the health of his workmen by requiring them to drink no water
but what was known to be wholesome and was brought from a distance.

HYDRAULIC FILTERING PRESS FOR TREATING OLEAGINOUS SEEDS.
Messrs. Laurent Bros. & Collot exhibited at the Paris Universal
Exhibition in 1878 a patented hydraulic apparatus styled a filtering
press, the principle and construction of which it will prove of interest
to describe. The apparatus is remarkable for its simplicity and ease of
manipulation, and is destined to find an application in most oil mills.
