Of the vast, the immeasurable value of such services," to quote the words of the Quarterly Review (No. cxxix. Dec. 1839), "which able officers thus employed, are in the mean time rendering to science, to commerce, to their country, and to the whole civilized world, we need say nothing:— nothing we could say would be too much."
"In five years, the admirable maps of that coral-bound gulf—the Red Sea—were complete: the terrors of the navigation had given place to the confidence inspired by excellent surveys. In 1829 the Thetis of ten guns, under Commander Robert Moresby, convoyed the first coal ship up the Red Sea, of the coasts of which this skilful and enterprising seaman made a cursory survey, from which emanated the subsequent trigonometrical operations which form our present maps.

Some idea may be formed of the perils these officers and men went through, when we state the 'Benares' was forty-two times aground."
"Robert Moresby, the genius of the Red Sea, conducted also the survey of the Maldive Islands and groups known as the Chagos Archipelago. He narrowly escaped being a victim to the deleterious climate of his station, and only left it when no longer capable of working. A host of young and ardent officers—Christopher, Young, Powell, Campbell, Jones, Barker, and others—ably seconded him: death was busy amongst them for months and so paralyzed by disease were the living, that the anchors could scarcely be raised for a retreat to the coast of India. Renovated by a three months' stay, occasionally in port, where they were strengthened by additional numbers, the undaunted remnants from time to time returned to their task; and in 1837, gave to the world a knowledge of those singular groups which
