The discovery of the Achilles, Rawlins County, Kansas, meteorite (ECN = + 1008,398; cl. = veined crystalline chondrite, Cka) was made by the Homedale brothers in 1924. The meteorite remained unrecognized for 26 years, until Mr. Anthony Halner noticed the similarity between it and specimens in the H. O. Stockwell display at the Kansas State Fair. The meteorite weighs 12,020 gm. and is covered by a fusion-crust. The original weight is estimated as 16 kg. The meteorite is preserved in the collection of Mr. Stockwell.

Six (6) dual observations of meteors, made with the naked eye and with a telescope or binoculars, are discussed. It is found that one (1) was a “point” meteor. Two (2) were “line” meteors seen with the telescope or binoculars before being noticed with the naked eye and at below-the-naked-eye magnitude. Three (3) were “line” meteors, for which the binocular and the naked-eye observers recorded essentially the same real magnitudes.

The Weaver Mountains, Arizona, meteorite has been reanalyzed. The new results confirm those of the previously reported analysis of this meteorite. The specific gravity first reported, 7.108, was found to be incorrect; this was redetermined and found to be 8.07. The Weaver Mountains meteorite has similar metallographic structures to the Babb's Mill, Tennessee, and the Shingle Springs, California, meteorites. These 3 meteorites are nickel-rich ataxites, and the ground-mass of each consists of imperfectly transformed γ-α structures, in which occur small bodies of kamacite.

This paper presents certain historical facts relating to the discovery of meteorites in the neighborhood of the Odessa, Texas, Meteorite Crater; a discussion of the distribution and other characteristics of the meteoritic materials so far recovered by surface and subsurface search at that crater; a detailed mineralogical and metallographic study of the metallic phase of the meteorite; and chemical and radiochemical analyses of the sideritic material. The results of the investigation, insofar as they relate to the unaltered nickel-iron, are consonant with the classification of Odessa as a coarse octahedrite (Og). Two (2) figures and 2 tables are given.

The history of the recovery of the masses that comprize the Glorieta Mountain, New Mexico, siderite is reviewed. The present paper is based on a detailed mineralogical, metallographical, and chemical investigation of the remarkable cane-shaped specimen from the Department of Geology of the University of New Mexico. The meteoritic constituents present are kamacite, taenite, plessite, schreibersite, and lawrencite. The meteorite is classified as a medium octahedrite (Om).

In the first section of this paper, historical evidence concerning injuries occasioned by falling meteorites, including the recent Aba, Japan, incident described by I. Yamamoto and S. Murayama in the preceding notes is presented. In the second section, the possibility of injury from meteoritic falls is critically examined from the viewpoint of the theory of probability. It is found that the probability of a hit on the Human Target-Area (HTA) of Europe (or of America) during any century between 1600 a.d. and 2200 a.d. is very small. There are, however, about 316 chances out of 1000 that at least one meteorite will strike in the world's HTA during the 20th century. Furthermore, there is very nearly a 50–50 chance for at least one meteorite to hit in the same HTA during the 3 centuries from 1700 to 2000 a.d. Finally, the odds are 99 to 1 that in at least one of the centuries between 2100 and 3300 a.d. at least one meteorite will hit in the world's HTA.

A number of old and new etching reagents for meteorites have been tested. None was found to be superior to those already in general use, except that the recent report that the addition of a little glue gives improved results is confirmed. Some other colloidal additives also were found to give a better etch, but none was better than glue. A few other experiments also are briefly mentioned. All workable reagents give the same kind of figures.
