Astrologically we regard the Earth as the passive subject of planetary influence, and we have therefore to regard it as the centre of the field of activity. If we were making a horoscope for an inhabitant of the planet Mars, we should make Mars the centre of the system. The planets’ positions are therefore taken as from the centre of the Earth (Geocentric), and not as from the centre of the Sun (Heliocentric). An astrological Ephemeris of the planets’ motions is employed for this purpose (see Sect. II., chap, i.), and there are 480,000 of these sold to astrologers or students of astrology every year, from which fact it is possible to draw one’s own conclusions as to the state of Astrology in the West. These figures, of course, do not include the millions of almanac readers nor the Oriental students, who prepare their own ephemerides. Knowing the simple natures of the several planets we are able to arrive at an estimate of their effects when acting in combination. _Neptune_ acts upon the mind of man to produce a highly-strung nervous temperament, often allied to either insanity or genius; neurosis, aphasia, &c. It produces complications in business and an involved state of affairs generally. Disposes to fraud, double-dealing, and irresponsible actions. In the body it produces waste of tissue and a consumptive habit. _Uranus_ gives an eccentric mind, waywardness, originality, inventiveness. Acting on the affairs of business, it produces sudden and unexpected developments, irregularities, rapid rise and fall, instability, unexpected turns of good and bad fortune. In the body it has relation to the nervous system, and its diseases are those of paralysis, lesion, and nervous derangement. _Saturn_ produces a thoughtful, sober, ponderable mind; steadfastness, patience, and endurance; disposition to routine and habit, method. In financial affairs it gives steady results commensurate with labour, success that is slow but sure, durance, hardships, privations. In the body it is related to the osseous system, and its effects are brought about by obstructions, chills, and inhibition of function. _Jupiter_ gives joviality, optimism, bountifulness, generosity, a rich and fruitful mind. It renders the subject fortunate in his affairs, giving success and frequently opulence. With this planet strong in the horoscope a person never “goes under.” In the body it has relation to the arterial process, and its diseases are those which arise from surfeit, congestion, and plethora. _Mars_ confers a sense of freedom, much ambition and executive ability, frankness, truthfulness, and scorn of consequence. It renders the mind forceful and militant, stimulates to new projects and enterprises, and in the body of man has relation to the muscular system. Its diseases are those which arise from inflammatory action in the tissues.
