The north-west "Gregale" (Euroclydon of Acts xxvii. blows about the equinox, and occasionally, in the winter months, sometimes with almost hurricane force for three days together; it is recorded to have caused the drowning of 600 persons in the harbour in 1555. This wind was a constant menace to shipping at anchor; the breakwater on the Monarch Shoal was designed to resist its ravages. The regular tides are hardly perceptible, but, under the influence of barometric pressure and wind, the sea level occasionally varies as much as 2 ft. The average rainfall is 21 in. ; it is, however, uncertain; periods of drought have ex tended over three years. Snow is seen once or twice in a genera tion; violent hailstorms occur.

Undulent fever was traced by Colonel, now Sir David Bruce to a micrococcus melitensis. The supply of water under pressure is widely distributed and excel lent. There is a modern system of drainage for the towns, which is being extended to the villages, and all sewerage has been intercepted from the Grand Harbour. There are efficient hos pitals and asylums, a system of sanitary inspection, and mod ernized quarantine stations.
