1912. Astrology For All series, Volume 4. How to Judge a Nativity Part 2, a continuation of How to Judge a Nativity. Astronomy represents the mathematical aspect of astrology; possessing a mechanical turn of mind, anyone exercising patience, industry and perseverance may become a capable astronomer. There are few competent to judge a nativity when it is cast, and many desiring a true delineation of their own horoscopes, or those of others, are often disappointed through the incompetence of unskilled professors. Is it not better to profit by your own mistakes in the attempt to judge your nativity, than to pay dearly for the mistakes of others? Certainly! Then make the attempt and be your own astrologer.
