IN in u 1 le last month, special attention was paid 

 to the occurrence ol iron and nil kel in meti 11 ite 

 and sid< 1 iliti >. Km ■ tl 1 < important con- 

 stituents hitherto identified, there have been found, in 

 quantities the following 1 iron, magnesium, 

 my, silicon, oxygen, nickel, cobalt, chromium, 

 manganese, titanium, tin, copper, aluminium, 



Mbtboritb, iii' Wkst Liberty, Iowa, [875. 

 potassium, sodium, calcium, lithium, arsenic, phos 

 5, nitrogen, sulphur, chlorine, carbon, hydrogen. 

 Among the minerals there have been identified 

 enstatite, triclinic, felspar, chromite, peridote, mag 

 pyrites, pyroxene, iron oxide, graphite, 

 schreibersite, oldhamite, laurencite, and daubreelite, 

 with, perhaps, traces ,,1 one "r two others, 

 these ,1" nol appear t>> have been vei\ ri 

 The gases obtained by analysis include hydrogen 

 gi I.. .1 i alread] stated. Cart* mic acid gas, 

 and carbonic oxide In association with hydrogi 

 found in the stony meteorites. The latter gas is 

 most abundant. Traces of nitrogen have 

 been detected. 



The evanescenl charactei ol the ■rain following 

 the path through the sky, of a meteor, rendei 

 vation and accurate definition of its character and 



origin extremely difficult. Attempts have been made, 

 though with hut limited success, to investigate the 

 phenomenon by the aid of the spectroscope. It may, 

 1 iwever, be said that the results are so small, that 

 with the exception of the usual lines representing 

 oxygen and hydrogen, little else has been identified. 

 li. colour of the trail of light varies considerably, 

 and is probably due t,> the gases released during com 

 bustion, nfiuenced by the sodium, mai 

 other metal or mineral near the surface ol the 

 irite, whilst being consumed. 

 Returning to the Gregory ' ill ion of 



VI tes, it contains examples ol upwards ol foui 



hundred distinct falls, anil somewhat in,, re than live 

 hundred and fifty specimens. These may be divided 

 into 225 stone meteorites or aerolites, 155 examples 

 of meteoric iron, and 24 siderolites, some of the 

 various sections being in duplicate. The collection is 

 especialh rich, that it has been entirely 



the work of an individual and without Government 

 aid, in examples of the ancient falls: which are now 



Mbtboritb, fell 1803, L'Aiglb, Fk-,-., 



unattainable, unless some public or private collection 

 is dispersed.
