tices are conducted with the greatest skill, my sons can testify that 

 the mere name of an English miner every where called forth the kind- 

 est welcome, and every where opened the door to all kinds of infor- 

 mation which they were in search of; I therefore cordially cherish the 

 feeling that we ought not to be outdone in such generous sentiments. 

 I would fain, gentlemen, now communicate to you how I am im- 

 pressed by the honours you have conferred on me this day; but in 

 this I should fail if I ventured to enlarge upon it, and I must attempt 

 but little, inadequate as any thing I could say would be to give a 

 just picture of my feelings on this occasion. Arduous and almost 

 overpowering as many of my duties have been, I have been cheered 

 on by the kindness of friends, or by those who have reaped ad- 

 vantage from successful efforts ; — how much more must I value this 

 unlooked-for and spontaneous expression of approbation from those 

 whose regard is so disinterested, whose favour I have had so few 

 means of cultivating 1 Gentlemen, the impression you have made on 

 my mind is too deep to vent itself in complimentary words ; it will 

 remain a theme of grateful recollection and a stimulus to exertion, 

 and it will associate itself with all the best wishes for you and yours 

 that you can desire or that I can offer. 



THORITE, A NEW MINERAL, AND THORINA, A NEW EARTH. — 

 BY M. BERZELIUS. 

 A new mineral substance, discovered near Brevig in Norway by 

 M. Esmark, was sent to me for examination. It is compact and 

 black, brittle and semi-hard ; it has the vitreous fracture of gadolinite; 

 when powdered it is of a dark brown colour 5 its sp. gr. is 4*8. 

 Under the flame of the blowpipe it loses water, and becomes yellow. 

 This mineral is a new earth, which has so many properties belonging 

 to the substance formerly called thorina, that I thought at first the 

 mineral actually contained it. This was not confirmed by experiment, 

 but I have nevertheless retained the name of thorina. This mineral 

 is constituted of
