[Jan., 



Ireland, on the 12th August, 1865. This stone was given by the 

 observer and finder, John Johnson, of Clonoulty, to Lord Hawarden, 

 and presented by his lordship to the Geological Museum of Trinity 

 College. Professor Haughton has determined its composition 

 to be : — 



Nickel Iron . 



Protosulphuret of Iron 



Chrome Iron . 



Mineral soluble in Mu- 

 riatic Acid, probably 

 Chrysolith 



Minerals insoluble in 

 Muriatic Acid

There can be no doubt but that this is a true meteoric stone, its 

 composition agrees so closely with that of others. The " statement 

 by an eye-witness," who says, " I heard a clap like the shot out of 

 a cannon, very quick and not like thunder ; this was followed by a 

 buzzing noise, which continued for about a quarter of an hour, 

 when it came over our heads, and on looking up we saw an object 

 falling down in a slanting direction," &c, &c, is rendered of very 

 uncertain value by the exaggerations contained in it. 



The " Colorado Meteorite," as it is called, which is stated to 

 have been found in "Kussel Gulch, Feb. 18, 1863, by Mr. Otho 

 Curtice," weighs 291bs. It has been examined by Professor J. 

 Lawrence Smith, of Louisville, and its composition found to be :* —

Gay-Lussite has been found by Professor B. Silliman in great 

 quantities at the Little Salt Lake, near Kagtown, Churchill Co., 

 Nevada. These crystals have been examined by Mr. John M. 

 Blake, who shows that in crystalline form these specimens differ in 

 some respects from such as have been previously measured.f
