This page is helpful for determining what the pictures actually contain: http://green-door.narod.ru/zaintarot.html

It contains C.C. Zain's notes that accompany the images in the Church of Light's book.  Here's what it says about this card:

The Alchemist.--Arcanum XIV.

In Divination, Arcanum XIV is Regeneration or Temperance.

Arcanum XIV is figured by the genie of the sun holding a golden urn and a silver urn, and pouring from one to the other the conducting fluid of life.

The genie is crowned with flame to indicate that it is a spirit; and its feet are winged to signify its rapid movements. The fluid transferred from one urn to another is the symbol of transmutation; and the eight rays of the sun which show behind the genie's head signify that the positive, or masculine, forces of the universe are exactly equilibriated by the negative, or feminine, forces. The cloak over the shoulder of the spirit indicates the perpetual fecundation of matter, as symbolized by the cloak, by spirit.

This ensemble pictures the combination and interchange of masculine and feminine forces throughout nature, working ceaselessly in all kingdoms, as the instigators and cause of all movements and life.

It's helpful because it tells you what the elements are, but reading it makes me think of Ra's comment that "We may note, with sympathy, that you undoubtedly feel choked by the opposite difficulty, that of a great mass of observation upon this system, all of which has some merit as each student will experience the archetypical mind and its structure in an unique way useful to that student."
