JUNE, 1910. METEORITE StupiEs III — FarRINGTON. ie 
cavities of circular form and angular depressions between angular 
elevations. These angular elevations doubtless represent the octa- 
hedral structure of the meteorite. The fact that the octahedral 
structure is thus brought into relief indicates that this pitting is due 
to a slow process of weathering and solution which the meteorite has 
undergone since its arrival on the earth. The larger pits are all 
doubtless produced by a process of weathering and solution, but the 
cause of their size and shape is not clear to the writer. Pits of the 
same general nature though much larger and deeper characterize the 
Willamette meteorite and were referred by Ward,* to a weathering 
process without any theory as to details. The rear side of the 
Quinn Canyon meteorite was, as has been stated, immersed in the 
soil and this gave, probably, moisture which aided solution of the iron. 
Carbonate of lime in the form of a whitish, closely adhering deposit 
covered, when the meteorite arrived at the Museum, the portion 
which had been imbedded, about the sides but not to any extent on 
the bottom, that is, the flat surface. The larger pits contained a 
considerable deposit of hydrous iron oxide in the form of scales which 
could easily be pried off. The side of the meteorite which had not 
_ been imbedded showed no weathering. 
In connection with his account of the finding of the meteorite, Mr. 
Jenney described the passage of a large meteor over the region Feb- 
ruary I, 1894. This account he repeats and elaborates in a later 
articlef and considers it highly probable that the Quinn Canyon 
meteorite fell at this time. While there seems nothing impossible 
in the view, it is also true that there seems no way of positively con- 
necting the two occurrences. The decomposition seen on the im- 
bedded portion of the meteorite might seem to have required a longer 
time than fourteen years for its production, but no definite means 
of measuring thisis known. The slight depth to which the meteorite 
was imbedded in the soil shows that it must have reached the earth 
with a very low velocity, in fact, so low that it is difficult to conceive 
how so large a mass could have alighted so gently. The assumption 
of a path nearly tangential to the earth’s surface and a direction of 
motion similar to that of the earth seems the only way of explaining 
‘so slight a vertical penetration. 
In order to determine the character of the etching figures of the 
meteorite two small fragments, weighing 9 and 15 grams respectively, 
have been cut from it since its arrival at the Museum. The surface
