9S PRESUMED ALTITUDE OF THE which is much used in food throughout this picturesque province, promotes this loathsome disease !

The chain of Atlas, east of Marocco, continually covered with snow, gives a pleasant coolness to the air of the city, in the summer season, particularly in the morning and evening ; the coolness is generally said, however, to produce ophthalmia. These mountains are immensely high, and their magnitude makes them appear not more than five miles from the city.

It is, however, a day's journey to the foot of them, after which the ascent is so gradual, that it takes two days more to reach the snow. This part of the chain of Atlas, east of the city of Marocco, is seen at sea, twenty miles west of Mogodor, which latter place is about 120 miles from Marocco ; it is 35 miles from the city of perfectly wholesome, and deprived of any leprous or other bad quality : Take a quart of Argan oil, and put in it a large onion cut in slices ; when it boils add a piece of crumb of bread, equal in size to an onion, then let it boil a few minutes more, take it off, let it cool, and strain the oil through a sieve, and bottle it for daily use.

<= Ophthalmic disorders prevail among the Jews of Marocco, but are seldom seen among the Moors. The Jews live in great filth at Marocco ; the dung-hills and ruins are in some places as high as the houses. The Muhamedan doctrine does not allow the Moors to neglect personal cleanliness, which, among these people, is a cardinal virtue ; and this, I presume, is the cause of their being, in a great measure, exempt from ophthalmia, whereas the Jews, on the contrary, are generally affected with it.
