For properly observing these objects, a power of not less than 300 on telescopes of large aperture is needed; and in studying their minute and delicate details, we are perhaps more dependent on atmospheric conditions than in following up any other branch of observational astronomy.
With training and opportunity he ought to develop into a fine man for greater responsibility than he now carries." Perhaps, in some ways, an even more convincing evidence of the reliability and practicability of the observational method may be found in the results obtainable by analysis from photographs. A photograph is, in a sense, a purely mechanical product.
The publication of Webb's "Celestial Objects" in 1859, the supposed physical change in the crater Linne, announced in 1866, and the appearance of an unrecorded black spot near Hyginus some ten years later, had the effect of awakening a more lively interest in selenography, and undoubtedly combined to bring about a change in this respect, which ultimately resulted in the number of amateurs devoting much of their time to this branch of observational astronomy being notably increased.
Our 'percipient event' is that event included in our observational present which we distinguish as being in some peculiar way our standpoint for perception. It is roughly speaking that event which is our bodily life within the present duration. The theory of perception as evolved by medical psychology is based on significance.
Both of the astronomers were heartily sick of spending so much of their observational time with recalcitrant equipment; and in making observations of the globe from which they had come. After all, why should an astronomer be interested in Earth? Though admittedly this was the first observatory in man's entire history that had had the opportunity for such a careful scrutiny.
His book, "The Triumphal Chariot of Antimony," is full of conclusions not quite justified by his premises nor by his observations. There is no doubt, however, that the observational method which he employed furnished an immense amount of knowledge, and formed the basis of the method of investigation by which the chemical side of medicine was to develop during the next two or three centuries.
"By means of experimental and observational work in science, not only will his attention be excited, the power of observation, previously awakened, much strengthened, and the senses exercised and disciplined, but the very important habit of doing homage to the authority of facts rather than to the authority of men, be initiated."
We have ventured to point out that it does not, as yet, satisfy all those requirements; but we do not hesitate to assert that it is as superior to any preceding or contemporary hypothesis, in the extent of observational and experimental basis on which it rests, in its rigorously scientific method, and in its power of explaining biological phenomena, as was the hypothesis of Copernicus to the speculations of Ptolemy.
It is probably one of the most thoroughly investigated reports in the UFO files and it contained the most precise observational data we ever received. Scientists from far and near tried to solve it. It remained an "unknown." The men who made the original sightings stuck by the case and furnished the "more detailed objective observational data" the Air Force speaks of.
