62 PHILOSOPHICAL TRANSACTIONS. [aNNO 1673. 



As to fevers at and about Aleppo, though they have the same type there as 

 in England ; yet there are two things peculiar in them. One is, that in acute 

 fevers, cold sweat commonly signifies recovery, but hot sweat portends death. 

 The other is, that in such acute fevers even an intermitting pulse denounces no 

 danger. 



The leprosy, which anciently was so frequent a malady in these countries, is 

 now scarcely to be found there ; though at Damascus there is still an hospital 

 standing, formerly built for the relief of persons so diseased. 



The reason why the city of Constantinople, is so much subject to the plague 

 is, according to some, owing to the multitude of slaves, yearly brought by the 

 Black Sea, and their hard diet and usage : according to others, it is owing to 

 the common people, feeding for the greatest part of summer on cucumbers and 

 melons, and drinking water upon them, without the use of helps to correct the 

 crudities. But the physicians generally conclude, that tlie air of Constantinople 

 is infected by the north-east winds, which blow commonly for 3 months, be- 

 ginning about the summer solstice^ arising from unwholesome marshes in 

 Tartary and Muscovy. 



Besides the other uses of opium in Turkey, it is common in Arabia, to cure 

 horses with it of the griping of the guts. 



As to the way of dressing leather in Turkey, it is to be observed, that their 

 leather is not so strong and serviceable as that in England. And though it be 

 commonly said, that the leather in these parts, though thin and supple, will hold 

 out water ; yet this is to be understood, that the Turks in their winter-boots, 

 between the lining and the leather, put a sear cloth ; which being curiously 

 sowed in the seams, will keep out water, though you put them in it for some 

 hours together. In cleaning their leather, they use lime and album Graecum ; 

 and instead of bark of trees, they employ valonia, a sort of acorn. I am per- 

 suaded that our acorns in England, if they could be spared for it, would per- 

 form the like effect, and perhaps better; seeing that the valonia often burns the 

 leather so much as to make it almost useless.

The processes followed in the making of foreign wines are detailed in so many 

 publications of modern times, that it cannot be necessary to lay before our 

 readers the description here given of the method of making rhenish wine.
