It is obvious that Astrology can never become an even approximately perfect science, unless we are able in our calculations to take fully into account the influence of ♅ and ♆. With this end in view, I have been endeavouring, in my leisure moments, to solve the problem. To a certain extent I have been successful; and though I have not yet been able to substantiate all my conclusions as fully as I could wish, yet I deem it is the best interests of the Science to make them now public, that their truth or falsity may be as speedily as possible established by the investigations of astrologers generally. My conclusions are the following: that the ancient Diurnal and Nocturnal divisions are quite correct, so that if a figure is drawn for any time between sunrise and sunset, the planets which rule by day the signs on the cusps of the houses of the significators must be chiefly, and sometimes exclusively, considered; and _vice versâ_. The Houses of the new planets are, I believe, these: ♒, which is the day-house of ♄, is the night-house of ♅. ♊, which is the day-house of ☿, is the night-house of ♆. ♍, which is the night-house of ☿, is the day-house of ♅. ♓, which is the night-house of ♃, is the day-house of ♆. The first two I have verified by horary figures drawn for the time of an event; the latter two I consider as highly probable, but have not yet been able to thoroughly substantiate them. There is an old tradition (_Esoteric Science in Human History_, p. 180) that there are 12 principal planets in our solar system; this leaves 4 more to be discovered. It will be seen at a glance that these 4 will fill up the vacant signs, two planets ruling each sign, one by night and the other by day. The only alteration which will then have to be made will be to consider ☉ to rule ♌ by day only, and ☽ to rule ♋ by night only; this, however, will be only in accordance with nature: moreover, the fact that the ancients assigned only one house each to ☉ and ☽, and two to each of the other planets, denotes some essential astrological difference between them. With regard to the other essential dignities, Raphael considers ♏ to be the exaltation of ♅; I am inclined to believe ♒ to be the exaltation of ♆. In the Triplicities there is a curious want of harmony; each, according to the ancients, being ruled by two planets, one by day and the other by night, except the watery triplicity, which is ruled by ♂ only. There seems to be no reason for this discrepancy, except the all-powerful one that there was no other known planet to share his dominion. I have ascertained that ♆ has strong dignity in ♏, and conclude that he rules the watery triplicity, probably by night. Furthermore, I believe ♅ rules the airy triplicity. As for the Terms and Faces of the planets, they also, like the Planetary Hours, require re-arrangement so as to bring in ♅ and ♆ but in what way this is to be done, I have not yet been able to discover.
