This paper includes an account of the recovery and a description of 8 more aërolitic particles, ranging in weight from 0.0628 to 0.0074 g., that were recently collected from ant hills at the site of the Holbrook, Arizona, fall of 1912. (The total number of such specimens now known is 11.) All 8 of these particles were discovered by means of “alnico” magnets—4 of the little stones in the field and 4 of them in the laboratory. The latter were detected in a quantity of 5515 g. of the ant‐mound gravel that was brought home for examination, and all 4 of these were found in the material of the same jar, which contained 771 g. of this gravel. From the data available, the ratios of both the numbers and the weights of the terrestrial and the meteoritic stones are calculated and various other comparisons between the 2 kinds of particles are made. Probably the most significant conclusion is that completely incrusted aërolites, weighing down to 0.0074 g., not only have been demonstrated to exist but have actually been reclaimed at the place of the Holbrook shower.
