A fresh north-east monsoon expedited our voyage, and we cut the equator on the 21st of January, in the longitude 253 deg. 38'; then passing between the islands of Sumatra and Java, we reached the ocean, after having safely traversed the Chinese Sea from its northern to its southern boundary, and directed our course towards the Cape of Good Hope, where we intended staying to refresh. When we had reached to longitude 256 deg., 12 deg. south latitude, the east wind, contrary to all rules at this season, changed for a westerly one, and blew a strong gale; the sky was covered with black clouds, and the rain fell in torrents. At midnight, while the storm was still raging, and the darkness complete, we witnessed the phenomenon known by the name of Castor and Pollux, and which originates in the electricity of the atmosphere; these were two bright balls of the size which the planet Venus appears to us, and of the same clear light; we saw them at two distinct periods, which followed quickly upon each other in the same place, that is, some inches below the extreme point of our main-yard, and at about half a foot distance asunder. Their appearance lasted some minutes, and made a great impression on the crew, who did not understand its cause. I must confess, that in the utter darkness, amidst the howling of the storm and the roaring of the water, there was something awful in the sight. Our passage was rendered tedious by contrary winds. On the 22nd of February, we crossed the meridian of the Isle of France, three hundred and forty miles off the island, in very stormy weather, and heard afterwards at St. Helena, that a hurricane raged at this time near the Isle of France, causing great damage to many vessels, and to some of them the loss of their masts. We should have probably shared in this danger had we been a hundred miles nearer the coast. I must here recommend every navigator, if possible, to keep clear of the two isles of France and Bourbon, from the middle of January till the middle of March, as, during that season, violent hurricanes continually rage there, which are very destructive even on shore. On the following day we passed the large frigate Bombay, belonging to the English East India Company, having on board, as passengers, the Governor of Batavia, Baron vander Kapellen, and his lady, with whom we afterwards had the pleasure of forming an acquaintance in St. Helena. On the 15th of March we doubled the Cape of Good Hope. It had been my intention to anchor in Table Bay, but a storm from the north-west came just in time to remind us how dangerous the bay is at this season, and we prosecuted our voyage to St. Helena. On the 25th of the same month, having traversed 360 degrees of longitude from east to west, we had lost a day, and were therefore compelled to change our Friday into a Saturday.
