In Captain Krusenstern's Memoir on the Lands of the Icy Sea, 

 it is related that 250 versts of the coast of a northern land was very 

 lately explored, which has been called New Siberia; and at the 

 easternmost part of this land the coast took a direction to the north- 

 west, which appeared to render it not probable that it joined the 

 Tschuktzki land : but nevertheless, the coast, in Captain Burney's 

 opinion, may turn to the east ; and the Russian discoverer Heder- 

 stroom considers that this is the case, and that New Siberia is a 

 prolongation of America. The Tschuktzki people, says the author, 

 would not explore further north than afforded a prospect of reward 

 for their pains, which has led them to some of the islands of the Icy 

 Sea, though there is no evidence of their having yet reached New 

 Siberia. On the whole, Captain Burney is of opinion that Asia and 

 America are part of one and the same continent. 



Additional Facts respecting the Fossil Remains of an Animal, on the 

 subject of which two Papers have been printed in the Philosophical 

 Transactions, showing that the Bones of the Sternum resemble those 

 of the Ornithorhynchus paradoxus. By Sir Everard Home, Bart. 

 V.P.R.S. Read January 22, 1818. [Phil. Trans. 1818, p. 24.] 



In an engraving annexed to Sir Everard Home's first paper upon 

 the above subject, a portion of bone is shown lying upon the scapula, 

 which he considered as a portion of a rib accidentally brought there; 

 but which he now finds to be nearly in its original situation, and is 

 found to resemble nearly the clavicular bone in birds, as far as regards 

 relative position. 



The bones of the sternum were first pointed out to the author by 

 Mr. Buckland ; and their discovery destroys the analogy between this 

 fossil animal and cartilaginous fishes. On comparing the general 

 form of the sternum with that of the Ornithorhynchus paradoxus, a 

 general agreement was discovered between them : they differ in the 

 fossil skeleton having a clavicular bone, which is wanting in the 

 other, and in the Ornithorhynchus having a long process from the 

 scapula, which the fossil bone wants. 



The fossil animal is ascertained to have lived in water, by the form 

 of its vertebrae ; and from the shape of the chest, it must have breathed 

 air ; in these respects resembling the Ornithorhynchus : but the mode 

 of progressive motion differs : that of the one being the same as in 

 fishes, that of the other the same as in the whale tribe. 



Another bone is described in this paper, probably belonging to the 

 same animal, and which the author regards as the first bone of the 

 pectoral fin ; which, however, cannot be absolutely determined till 

 the bones of the pelvis are found. 



To find any analogy, says the author, between the bones of animals 

 now alive and those of races long extinct, is matter of no small cu- 

 riosity ; but to have discovered an analogy between the peculiarities 

 belonging to the animals of New Holland, by which they are so 

 remarkably distinguished from all others that now inhabit our globe,
