ABSTRACTAn investigation made in 1929 brought to light the following facts concerning the aerolite of Rancho de la Presa, Zenapecuaro, Michoacan, Mexico. This stone was seen to fall in 1899—the exact date of the fall is unknown—by two Mexican women. The original weight of the meteorite was above 300 g. The main mass is preserved in the State Museum at Morelia, the capital of Michoacan, while 63 g. are in the Institute of Geology at Mexico City and 3 g. are in the Field Museum of Natural History at Chicago, Illinois. The aerolite should be classified probably as a brecciated, veined, gray chondr

摘要:

ABSTRACTAltho the compressive strength of meteorites is important in relation to the detonation of meteorites in flight and probably in other connections in meteoritics, only one determination of it existed prior to this study. The compressive strength of 8 stones, ranging from 900 to 54,000 lb./in2., is reported.

摘要:

ABSTRACTThis paper presents eyewitness accounts of the phenomena attending the fall of the Pultusk, Poland, meteorites. On the basis of the observational data thus provided, the real path and the heliocentric orbit pursued by the meteorites are determined.]

摘要:

ABSTRACTMention is made of free nitrogen, titanium nitride (osbornite), cyanogen, and previously reported occurrences of ammonium compounds in meteorites. Ammonia is reported as present in all of the 8 meteoritic stones tested. A new method of analysis is described which was used to determine the amount of ammonia in stones of 5 falls. In Holbrook, Arizona, the ammonia is shown to be present as a compound, at least partly soluble in water. The nitrogen found by Lipman appears to have been largely ammonium nitrogen. Lipman's failure to find water‐soluble nitrates or nitrites is confirmed; in addition, no cyanides were found in Holbroo
