“…A stream search based on conventional methods revealed seven new photographic showers (McCrosky and Posen, 1959). Three of the minor showers found by McCrosky and Posen also appear as separate showers in our data (Table 3).…”

“…The mean orbital elements do not differ appreciably from those published in other lists of meteor stream orbits determined by the Harvard Meteor Program (McCrosky and Posen, 1959;Jacchia, 1963). It follows that orbital data obtained by the graphical reduction procedure of McCrosky and Posen are sufficiently accurate for use in a computer stream search.…”

“…A few meteors originally classified as sporadic have in subsequent papers been reclassified as shower meteors; these reclassifications are listed in various papers of the Harvard Meteor Program (Wright, Jacchia, and Whipple, 1957;McCrosky and Posen, 1959) …”

“…In the case of the Virginid stream the precision of the orbital data is not sufficient to decide if the observed separation into two branches is significant. The 8-Arietid stream (McCrosky and Posen, 1959) also consists of a northern and a southern branch. Only two members of the southern branch are present in the McCrosky and Posen sample, however, and the computer search incorporated these in the northern branch.…”

This series, Smithsonian Contributions to Astrophysics, was inaugurated in 1956 to provide a proper communication for the results of research conducted at the Astrophysical Observatory of the Smithsonian Institution. Its purpose is the "increase and diffusion of knowledge" in the field of astrophysics, with particular emphasis on problems of the sun, the earth, and the solar system. Its pages are open to a limited number of papers by other investigators with whom we have common interests.The policy of issuing the Contributions in volumes consisting often of unrelated papers numbered sequentially ended with volume 11. With this issue (No. 12), each Contribution will bear a single series number and will contain either one or several related papers.

“…It is often represented by large objects. Detailed analysis of fireball data published by McCrosky et al (1978McCrosky et al ( , 1979, Ceplecha (1978) and Babadzhanov and Getman (1980) shows "ordinary chondritic" material to appear abruptly near the outer edge of the 1:3 gap, reach a sharp maximum inside the gap and slowly decrease near 1 A.U. "Carbonaceous" material shows a more uniform distribution with the main maximum near 2.3 A.U.…”

If we investigate the interrelations among different classes of small solar system bodies, we must be aware that we deal with nonrepresentative and practically noncomparable data samples consisting of bodies differing either in size, or in orbits, or in their nature. So, practically, all our knowledge about small bodies - from kilometer-sized Apollo asteroids (including Atens) and Amor asteroids (designated below as AA bodies) to fine dust particles - refer to bodies on orbits intersecting the ecliptic plane at a heliocentric distance ≃ 1 A.U. To solve the problem of origin of this ensemble it would be advantageous if analogous data could be obtained at least for one more heliocentric distance. Since planetary atmospheres are excellent detectors for small cosmic objects, the necessary data could be obtained with the aid of artificial satellites orbiting a planet, e.g. Mars or Venus. Thus the source for the ensemble of Earth-crossing objects may not be correctly pictured. Are comets or asteroids the general supplier? We know the answer to this question only in two cases: (1) meteor streams such as the Leonids originate from comets, (2) meteorites originate from asteroids. But these two categories represent a minute part of the considered ensemble by mass. As to its other members- the selection of the source is a matter of tradition rather than a logic conclusion.
