The lessons were donated in mimeographed or photocopied typescript form, in three ring binders.

The material is without dating or copyright information.

Intrinsic dating evidence as follows:

Arabian Astrology: "...Pluto in 1932 remaining hypothetical...." (p. 31)
Directional Astrology: "...prior to the writing of this lessons (in February, 1932)..." (p. 3)
Divinatory Astrology: none
Hegelian Astrology: "...in 1939 will come a marked Leo dynasty" (p. 104).
Hermetic Astrology: none
Divinatory Astrology: none
Sabian Astrology I: "...chart "B" for Chicago, June 6 , 1929..." (p. 6a)
Sabian Principles: "...have had some revision in January, 1950..." (pp. 101-2)
Symbolical Astrology: none

The lessons were purchased from a book dealer in Rockford, Illinois, who in its turn had purchased the lessons as an uncatalogued part of the inventory of another bookdealer, bought in a lot.

The lessons are rich in typographical errors, hand-drawn symbols, signs of proof-reading, and in-line edits, which latter do not suggest, in all cases, that the material is being copied from other sources (which is certainly the case with some in-line edits), but appear rather to be the false starts and reconsiderations of authorship. See, for example, Arabian Astrology, pp. 10, 19; Directional Astrology, pp. 34, 71; Hegelian Astrology, pp. 83.
