Note 94 — SECTION II. PHYSICAL GEOGRAPHY OF ICELAND.

Ozone is utterly absent during the Sharki or Scirocco of Syria, and the trying effects of the east wind upon the constitution are well known to every resident. This is the more curious as it exists in the adjoining desert, when in the Nile valley and in the oases it is comparatively deficient. It has lately been proved to be everywhere more abundant in winter than in summer.
