SEARCH FOR NITRE, AND THE TRUE NATURE OF GUANO, BEING AN ACCOUNT OF A VOYAGE TO THE SOUTH-WEST COAST OF AFRICA; ALSO A DESCRIPTION OF THE MINERALS FOUND THERE, AND OF THE GUANO ISLANDS IN THAT PART OF THE WORLD. BY T. E. EDEN, JUN., MEMBER OF THE ROYAL COLLEGE OF SURGEONS IN LONDON. LONDON: R. GROOMBRIDGE AND SONS, 5, PATERNOSTER ROW. GRAPEL, LIVERPOOL; AND ROBERTSON, GLASGOW. 1846. 847. PREFACE. THE portion of the African coast referred to in this book is situated between the 28th and 22d parallels of south latitude, and has not hitherto been described, except in 'A Narrative,' published by Morrell, an American ship-master, which is not to be depended upon. Morrell's voyage was made in 1828, and in 1836 Captain Sir J. E. Alexander undertook an expedition of discovery into the interior of Africa,' but his route, as laid down in the map, is seldom nearer than 120 geographical miles from the coast, and he did not reach the sea except at Walwich Bay. |
