other; and therefore a few words may suffice on this subject, to avoid cloying the judicious reader with what is so visible and plain, and to save running out this introduction to an unreasonable length. What was cosmography before these discoveries, but an imperfect fragment of a science, scarce deserving so good a name? When all the known world was only Europe, a small part of Afric, and the lesser portion of Asia ; so that of this terraqueous globe not one sixth part had ever been seen or heard of. Nay, so great was the ignorance of man in this particular, that learned persons made a doubt of its being round; others no less knowing imagined all they were not acquainted with desert and uninhabitable. But now geography and hydrography have received some perfection by the pains of so many mariners and travellers, who to evince the rotundity of the earth and water, have sailed and travelled round it, as has been here made appear; to show there is no part uninhabitable, unless the frozen polar regions, have visited all other countries, though never so remote, which they have found well peopled, and most of them rich and delightful; and to demonstrate the antipodes, have pointed them out to us. Astronomy has received the addition of many constellations never seen before. Natural and moral history is embellished with the most beneficial increase of so many thousands of plants it had never before received, so many drugs and spices, such variety of beasts, birds, and fishes, such rarities in minerals, mountains and waters, such unaccountable diversity of climates and men, and in them of complexions, tempers, habits, manners, politics, and religions. Trade is raised to the highest pitch, each part of the world supplying the other with what it wants, and bringing home what is accounted most precious and valuable; and this not in a niggard and scanty manner, as when the Venetians served all Europe with spice and drugs from India by the way of Turkey and the Red Sea ; or as when gold and silver were only drawn from some poor European and African mines; but with plenty and affluence, as we now see, most nations resorting freely to the East Indies, and the West, yearly sending forth prodigious quantities of the most esteemed and valuable metals. To conclude, the empire of Europe is now extended to the utmost bounds of the earth where several of its nations have conquests and colonies. These and many more are the advantages drawn from the labours of those who expose themselves to the dangers of the vast ocean, and of unknown nations; which those who sit still at home abundantly reap in every kind : and the relation of one traveller is an incentive to stir up another to imitate him ; whilst the rest of mankind, in their accounts, without stirring a foot, compass the earth and seas, visit all countries, and converse with all nations.
It only remains to give some few directions for such as go on long voyages ; which shall be those drawn up by Mr. Rook, a fellow of the Royal Society, and geometry professor of Gresham college, by order of the said society, and published in the Philosophical Transactions of the eighth of January 1665-6, being Numb. 8. They are as follow:
1. To observe the declination of the compass, or its variation from the meridian of the place, frequently : marking withal the latitude and longitude of the place where such observation is made, as exactly as may be, and setting down the method by which they made them.
2. To carry dipping needles with them, and observe the inclination of the needle in like manner.
3. To remark carefully the ebbings and flowings of the sea in as many places as they can, together with all the accidents ordinary and extraordinary of the tides ; as, their precise time of ebbing and flowing in rivers, at promontories or capes, which way the current runs, what perpendicular distance there is between the highest tide and lowest ebb, during the spring tides and neap tides, what day of the moon's age, and what times of the year the highest and lowest tides fall out: and all other considerable accidents they can observe in the tides, chiefly near ports, and about islands, as in S. Helena's island, and the three rivers there, at the Bermudas, &c.
4. To make plots and draughts of prospect of coasts, promontories, islands, and ports, marking the bearings and distances as near as they can.
5. To sound and mark the depth of coasts and ports, and such other places near the shore as they shall think fit.
6. To take notice of the nature of the ground at the bottom of the sea, in all soundings, whether it be clay, sand, rock, &c.
7. To keep a register of all changes of wind and weather at all hours, by night and by day, showing the point the wind blows from, whether strong or weak: the rains, hail, snow, and the like ; the precise times of their beginnings and continuance, especially hurricanes and spouts, but above all, to take exact care to observe the trade-winds, about what degree of latitude and longitude they first begin, where and when they cease or change, or grow stronger or weaker, and how much, as near and exact as may be.
8. To observe and record all extraordinary meteors, lightnings, thunders, ignes fatui, comets, &c. marking still the places and times of their appearing, continu
9. To carry with them good scales, and glass vials of a pint, or so, with very narrow mouths, which are to be filled with sea-water in different degrees of latitude, as often as they please, and the weight of the vial full of water taken exactly at every time, and recorded, marking withal the degree of latitude, and the day of the month; and that as well of water near the top, as at a greater depth.
This may suffice for sea voyages; but in regard it may be expected something should be said for those who travel by land, a few instructions have been collected from experienced travellers, who are best able to direct such as design to follow them into remote countries. We will therefore begin with Monsieur de Bourges, who with the bishop of Berytus made a journey through Turkey, Persia, and India, as far as Cochinchina. He advises such as intend for those
parts so to order their affairs, that they may come into Turkey in October, to avoid the excessive heats of those countries for four or five months before that time. If our traveller will hold on his journey to Persia, he must go with the caravan from Aleppo to Babylon, or Bagdat, which will take him up a month ; thence he embarks upon the river Euphrates, which carries him down to Bassora, whence he proceeds by sea to Bander, where he may find convenience by land to Ispahan, the capital of Persia : from Ispahan the difficulties of travelling by land to India are almost invincible, and therefore the proper way is to repair to the port of Gomrom, whence there is a constant and safe passage to Suratte, or any other part of India. that travel in Turkey must change their habit into that of the country, and must lay aside the hat, and wear a turban, and the meaner the habit the safer they will be from extortions and robberies : they must endeavour to have a Turkish interpreter on the road with them, who may own whatever goods they carry, and protect them against any affronts that may be offered them ; but above all, they must endeavour to be well recommended to the captain of the caravan, which will be their greatest safeguard. This recommendation must be from some of the Christian consuls, but generally the best from the French, who are much regarded in those parts. Such as will not carry all their stock in ready money, must be careful to carry those commodities that will turn to best account, amongst which the brightest yellow amber, and the largest red coral, are in great esteem. These, though not wrought, are profitable ; and to avoid the duties paid at several places, may be carried in a bag, or portmanteau, on the horse the traveller rides, for those are not searched. The best money they can carry are Spanish pieces of eight, provided they be full weight, and not of Peru, which are not so fine silver as the others. By this money they will have seven or eight per cent. profit in some parts, and ten per cent. in others, and the same in French crowns. As for gold, the greatest profit is made of the Venetian and Hungarian, and it is very considerable. There is so great an advantage to be made by those who rightly understand the best coins and their value, that those who are well instructed in it can travel for a very inconsiderable expense. It is absolutely necessary to carry good arms to defend themselves upon all occasions, but more particularly to fight the Arabs, and other rovers. Above all, it is requisite in Turkey that travellers be armed with patience to bear many affronts the infidels will put upon them, and with prudence and moderation to prevent, as much as possibly may be, any such insoIencies. They will do well never to go without provisions, because the caravans never stop to bait, and very often at night have no other inn but the open fields, where they lie in tents, and eat what they carry. When they travel with the caravan, they must take care never to be far from it, for fear of being devoured by wild beasts, or by the wilder Arabs. This in Turkey, for in Persia it is quite otherwise ; here we may travel in the European habit, and wear hats, which are better against the heat than turbans; the roads are safe, and the Persians courteous to strangers, especially the better sort. However, the traveller must watch the servants, and meaner sort of people of the country, who else will impose on him in matter of payments, of buying and selling; and therefore his best way is, where there are missioners, to repair to them, who will assist and instruct him. He must carry no gold into Persia, because it bears a low price, and he will be a great loser by it: the best way is to change his money on the Turkish frontiers into Persian coin, or else to carry a quantity of good amber and coral, which will yield profit, as will also good watches. In India Spanish gold yields some profit, though small, which the traveller may take notice of, in case he has no goods to carry that may yield a greater profit: this at Suratte ; but further in India, and particularly at Golconda, gold yields more, and especially old gold: however, at Siam again there is great loss in Spanish gold, and all other sorts, for there it is lower than in any other part of the East Indies nearer to us, and
