tation in adding, that he would be an ornament to His Majesty's ser-

*' Commander Ross, Mr. Thom, and myself, have, indeed, been 

 serving without pay ; but, in common with the crew, have lost our 

 all, which I regret the more, because it puts it totally out of my power 

 adequately to remunerate my fellow-sufferers, whose case 1 cannot 

 but recommend for their Lordships' consideration. We have, how- 

 ever, the consolatiou, that the results of this expedition have been 

 conclusive, and to science highly important, and may be briefly com- 

 prehended in the following words: — The discovery of the Gulf of 

 Boothia, the continent and isthmus of Eoothia Felix, and avast num- 

 ber of islands, rivers and lakes ; the undeniable establishment that 

 the north-east point of America extends to the 74th degree of north 

 latitude j valuable observations of every kind, but particularly on the 

 magnet j and, to crown all, have had the honour of placing the illus- 

 trious name of our Most Gracious Sovereign William IV. on the true 

 position of the magnetic pole. 



" I cannot conclude this letter, Sir, without acknowledging the 

 important advantages we obtained from the valuable publications of 

 Sir Edward Parry and Sir John Franklin, and the communications 

 kindly made to us by those distinguished officers before our departure 

 from England. But the glory of this enterprise is entirely due to 

 Him whose divine favour has' been most especially manifested towards 

 us, who guided and directed all our steps; who mercifully provided, 

 in what we had deemed a calamity, His effectual means of our pre- 

 servation; and who, even after the devices and inventions of man had 

 utterly failed, crowned our humble endeavours with complete success. 

 *' I have &c.

THEORY. 



There is a misprint in my paper on the Voltaic Theory, which 

 destroys the meaning of the passage. Vide Number for April, 

 page 253, paragraph 30. 



" By passing connecting wires along 13, 23, 33, 43, &c. M , " but 

 connecting them 13, 2c; 23, 3c; 33, fc, &c." 



The printer has mistaken z, the initial of zinc, for the figure 3: 

 the reading should be — 



" By passing connecting wires along lz, 2z, 3z, 4z, &c. ; and, 

 1 c, 2 c, 3 c, 4 c, &c. ; the whole six sets become a single pair ; but 

 connecting them 1 z, 2 c ; 2 z, 3c ; 3 z, 4c, &c, they become as many 

 pairs as there are sets." 



A less important error occurs at paragraph 28;Jbr " dilute nitric 

 acid (1-60)," read "dilute nitric acid (1 -.60), i.e. 1 acid to 60 

 water."
