ABSTRACTMeteoritic iron oxide occurs in three forms: coarsely lamellar, finely lamellar, and massive. The lamellar forms result from oxidation proceeding parallel to the surface of the metal. The thickness of the lamellae may be proportional to the rate of oxidation. Massive oxide results when electrolysis causes the oxide to invade the metal or when redeposition of dissolved oxide obliterates the original lamellar structure. The action of lawrencite produces a friable, porous type of oxide which is confined largely to specimens in collections. The effect of electrolysis on the differential oxidation of meteoritic minerals is briefly discussed. Three new analyses of meteoritic oxides (by F. G. Hawley) are given (Table 1).

摘要:

ABSTRACTThe place of meteorites in the cosmos is exhibited by means of what is called the Inventory of the Universe (Table 1). A Classification of Fallen Meteorites (Mi) (Table 2) is included in the article for convenience of reference. Several fundamental terms are defined and the subject of the paper is commented on briefly.

摘要:

ABSTRACTThis paper contains an account of a recently discovered 7.7‐gram aerolite (a chondrite) (Puente‐Ladron, Socorro County, New Mexico; coördinate number = 1068,344), together with an invitation on the part of the finder to all members of the S. R. M. to participate in a search for additional fragments of the

摘要:

ABSTRACTA description is given of the trail of a bright meteor appearing on a recent Crossley Reflector plate, and an attempted method of detecting the effect of the angular diameter of the meteor is outlined. A photographic light curve of the meteor was obtained and is shown in an accompanying diagram (Figure 2).

摘要:

ABSTRACT AND INTRODUCTIONAs far as I am aware, the accompanying photograph (Figure 1), obtained on October 15, 1934, at Claremont, California, is the only picture of a meteortraitwhich seems to show evidence of a wind at a high altitude in the Earth's atmosphere, altho several pictures of meteortrains* showing such evidence are in existence. The present photograph appears to be also the only picture exhibiting the meteorite within its gas cloud, unless the photograph secured by Charles M. Brown and reproduced as Figure 1 inP. A.,42, 291, 1934, and as Figure 3 inC.S.R.M.,1, No. 2, 38;P. A.,44, 387, 1936, should be counted. In that photograph,twobodies appear to be about toemergefrom a gas cloud.

摘要:

ABSTRACTThe coördinate numbers and classification of the Quartz Mountain and Quinn Canyon, Nye County, Nevada, siderites are given. Quartz Mountain, which closely resembles a typical Canyon Diablo, Arizona, iron, is apparently a very old fall, while Quinn Canyon is doubtless a much later arrival on the planet

摘要:

ABSTRACTThe place names “Windmill Station” and “Valley Wells,” California, refer to one and the same aerolitic fall, of which the coördinate number is 1157,355 and which should be known as “Val
