fathoms. In Capt. Owen's chart, and in that in the atlas of 

 the voyage of the Favourite, it appears that the east side 

 of Make and the adjoining islands of St. Anne and Cerf, 

 are regularly fringed by coral-reefs. A portion of the S.E. 

 part of Curieuse Isld., the N., and part of the S.W. shore of 

 Praslin Isld., and the whole west side of Digue Isld., 

 appear fringed. From a MS. account of these islands by 

 Capt. F. Moresby, in the Admiralty, it appears that Silhouette 

 is also fringed ; he states that all these islands are formed 

 of granite and quartz, that they rise abruptly from the sea, 

 and that "coral-reefs have grown round them, and project 

 for some distance." Dr. Allan, of Forres, who visited these 

 islands, informs me that there is no deep water between 

 the reefs and the shore. The above specified points have 

 been coloured red. Amir antes Islands : The small islands 

 of this neighbouring group, according to the MS. account 

 of them by Capt. F. Moresby, are situated on an exten- 

 sive bank ; they consist of the debris of corals and shells ; 

 are only about twenty feet in height, and are environed 

 by reefs, some attached to the shore, and some rather dis- 

 tant from it. — I have taken great pains to procure plans and 

 information regarding the several islands lying between 

 S.E. and S.W. of the Amirantes, and the Seychelles; 

 relying chiefly on Capt, F. Moresby and Dr. Allan, it 

 appears that the greater number, namely — Platte^ Alphonse, 

 Coetivi, Galega, Providence, St. Pierre, Astova, Assomption, 

 and Glorioso, are low, formed of sand or coral-rock, and 

 irregularly shaped; they are situated on very extensive 

 banks, and are connected with great coral-reefs. Galega is 

 said by Dr. Allan, to be rather higher than the other 

 islands ; and St. Pierre is described by Capt. F. Moresby, 

 as being cavernous throughout, and as not consisting of 

 either limestone or granite. These islands, as well as the
