Strona 98 - Yet still, from time to time, vague and forlorn, From the soul's subterranean depth upborne As from an infinitely distant land, Come airs, and floating echoes, and convey A melancholy into all our day.
Strona 205 - I am purposing them, to be considered of and examined, an account of a philosophical discovery which induced me to the making of the said telescope ; and I doubt not but will prove much more grateful than the communication of that instrument ; being in my judgment the oddest, if not the most considerable detection which hath hitherto been made in the operations of nature.
Strona 559 - The heat required to act upon such a compound as a salt of calcium so as to render its spectrum visible, dissociates the compound according to its volatility ; the number of true metallic lines which thus appear is a measure of the quantity of the metal resulting from the dissociation, and as the metal lines increase in number, the compound bands thin out.
Strona 227 - If the hydrogen-lines were invariably observed to broaden out on both sides, the idea of movement would require to be received with great caution ; we might be in presence of phenomena due to greater pressure, both when the lines observed are bright or black upon the sun ; but when they widen out, sometimes on one side, sometimes on the other, and sometimes on both, this explanation appears to be untenable, as Dr. Frankland and myself in our researches at the College of Chemistry have never failed...
Strona 475 - ... to the central umbra, are thus supposed to be due to the same cause, namely, the presence to a greater or less extent of a relatively cooler absorbing atmosphere.
Strona 139 - The line A that bounds the red side of the spectrum is somewhat confused, which seems in part owing to want of power in the eye to converge red light. The line B, between red and green, in a certain position of the prism, is perfectly distinct; so also are D and E, the two limits of violet. But C, the limit of green and blue, is not so clearly marked as the rest ; and there are also, on each side of this limit, other distinct dark lines, / and g, either of which, in an imperfect experiment, might...

Strona 437 - ... red flames" which total eclipses have revealed to us in the sun's atmosphere, although they escape all other methods of observation at other times?
Strona 248 - A faint continuous spectrum, without any traces of dark lines in it, was also visible, evidently due to the corona. Its light, tested by a tourmaline applied next to the eye, proved to be very strongly polarized in a plane passing through the centre of the sun. I am not sure, however, but that this polarization, as suggested by Professor Pickering, may have been produced by the successive refractions through the prisms. This explanation at once removes the difficulty otherwise arising from the absence...
Strona 559 - ... the spectrum of the compound consists in the main of channelled spaces and bands, which increase in like manner. In short, the molecules of a simple body and a compound one are affected in the same manner by quantity in so far as their spectra are concerned ; in other words, both spectra have their long and short lines...
