Page 212 - 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.
Page 234 - 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...
Page 194 - I conclude further, that the dark lines of the solar spectrum which are not evoked by the atmosphere of the earth, exist in consequence of the presence, in the incandescent atmosphere of the sun, of those substances which in the spectrum of a flame produce bright lines at the same place.
Page 528 - ... we were in a position to determine the atmospheric pressure operating in a prominence in which the red and green lines are nearly of equal width, and in the chromosphere, through which the green line gradually expands as the sun is approached.

Page 401 - But in the meanwhile the little " thunderhead " before alluded to had grown and developed wonderfully into a mass of rolling and everchanging flame, to speak according to appearances. First it was crowded down, as it were, along the solar surface ; later it rose almost pyramidally...
Page 20 - This gives the impression of a division between the luminous masses, especially with a comparatively low power, which, however, when best seen with high powers, is found to be never complete.
Page 148 - The position of the prism in which the colours are most clearly divided is when the incident light makes about equal angles with two of its sides. I then found that the spaces AB, BC, CD, DE, occupied by them, were nearly as the numbers 16, 23, 36, 25.
