The substance of this paper is comprized within 2 tables entitled respectively. “1. Numbers and Percents of Observed and Unobserved Falls of All Classes,” 1220 falls in all, recorded in Coulson's “Catalogue of Meteorites” (1940), and “2. Frequencies of Minimum and Maximum Percents of Observed Falls of the Principal Classes.” The data of these tables are briefly reviewed, and several conclusions are stated. It is a noteworthy if not a remarkable fact that at least one representative of every known variety of aerolite has been observed to fall; this suggests, among other things, that aerolitic material may be present on the Earth which has not been recognized as such, simply because no sample of it has been seen to fall.
