Horary Astrology, the chief subject in this work. may be speedily learned by any person of even moderate abilities; and may, as far as regards its elementary difficulties, be mastered in a few days' study. It may be well understood, and reduced to constant practice in less than a quarter of a year, and no one will find himself at a loss for occasions to test its reality or its utility; for his own avocations, and the affairs of his friends, will offer these almost daily. If a proposition of any nature be made to any individual, about the result of which he is anxious, and therefore uncertain whether to accede to it or not, let him but note the hour and minute when it was first made, and erect a figure of the heavens, as herein taught, and his doubts will be instantly resolved.
?He may thus, in five minutes, learn infallibly whether the affair will succeed or not; and, consequently, whether it is prudent to adopt the offer made or not. If he examine the sign on the 1st house of the figure, the planet therein, or the planet ruling the sign, will exactly describe the party making the offer, both in person and character; and this may at once convince the inquirer for truth of the reality of the principles of the science.
