According to these travellers, the Arabian merchants, no longer confining themselves to a traffic at Ceylon for the commodities of the east of Asia, traded to every part of that quarter of the globe, even as far as the south coast of China.  The account they give of the traffic with this latter country, is very minute:  “When foreign vessels arrive at Canfu, which is supposed to be Canton, the Chinese take possession of their cargoes, and store them in warehouses, till the arrival of all the other ships which are expected:  it thus happens that the vessels which first arrive are detained six months.  They then take about a third part of all the merchandize, as duty, and give the rest up to the merchants:  of these the emperor is the preferable purchaser, but only for ready money, and at the highest price of the market.”  One circumstance is particularly noticed, which proves, that at this period the Arabians were numerous and respected in China; for a cadi, or judge, of their own religion, was appointed to preside over them, under the emperor.  The Chinese are described as sailing along the coast as far as the Persian Gulf, where they loaded their vessels with merchandize from Bassora.  Other particulars are mentioned, respecting their trade, &c., which agree wonderfully with what we know of them at present:  they regarded gold and silver merely as merchandize:  dressed in silk, summer and winter:  had no wine, but drank a liquor made from rice.  Tea is mentioned under the name of sak—­an infusion of this they drank, and a large revenue was derived from the duty on it.  Their porcelaine also is described and praised, as equally fine and transparent as glass.  Every male child was registered as soon as born; at 18 he began to pay the capitation tax; and at 80 was entitled to a pension.

These Arabian travellers likewise supply us with some information respecting the trade of the Red Sea.  The west side of it was in their time nearly deserted by merchant ships; those from the Persian Gulf sailed to Judda on the Arabian coast of it:  here were always found many small coasting vessels, by means of which the goods from India, Persia, &c. were conveyed to Cairo.  If this particular is accurate, it would seem to prove that at this period the canal between the Nile and the Red Sea, which had been rendered navigable by Omrou, was regularly used for the purposes of commerce.

In these accounts, the typhon, or whirlwind, so common in the Chinese seas, is mentioned under that appellation:  the flying fish and unicorn are described; and we have notices of ambergrise, the musk, and the animal from which it is produced:  the last is mentioned as coming from Thibet.
