Seite 162 - At any rate, as few of the colours in nature are pure colours, but almost all arise from the combination of rays of different wave-lengths, and as in such cases the visible resultant would be composed not only of the rays which we see, but of these and the ultraviolet, it would appear that the colours of objects and the general aspect of nature must present to them a very different appearance from what it does to us.
Seite 283 - ... disturbed from the blue, she flew about a little and then lit on the white ; when the white was removed, she settled on the green ; and so on successively on the orange, yellow, plain, and red. I repeated the experiment a hundred times, using two different hives — one in Kent and one in Middlesex — and spreading the observations over some time, so as to experiment with different bees, and under varied circumstances.
Seite 284 - ... surrounding the stamens and pistil were green ; and that they have passed through stages of white or yellow, and generally red, before becoming blue. That all flowers were originally green and inconspicuous, as those of so many plants are still, has, I think, been shown by recent researches, especially those of Darwin, Miiller, and Hildebrand.
Seite 161 - Journ. voL xiv. p. 278) he had given a series of experiments made on ants with light of different colours, in order if possible to determine whether ants had the power of distinguishing colours. For this purpose he utilised the dread which ants, when in their nest, have of light. Not unnaturally, if a nest is uncovered, they think they are being attacked, and hasten to carry their young away to a darker, and, as they suppose, a safer place.
Seite 283 - I marked down successively the order in which the bee went to the different coloured glasses. For instance, in the first journey from the nest, as recorded...
Seite 168 - Thousands of creeping vermin were crushed by the wheels of the engine, and suddenly the train came to a dead stop. On examination it was found that the wheels of the engine had become so greasy that they kept on revolving without advancing — they could not grip the rails. The guard and the enginedriver procured sand and strewed it on the rails, and the train made a fresh start, but it was found that during the stoppage caterpillars in thousands had crawled all over the engine, and over all the...
Seite 72 - President, in the Chair. AFTER the minutes of the previous meeting had been read and confirmed, the following names were read for the first time :— Messrs.
Seite 162 - Now, as every ray of homogeneous light, which we can perceive at all, appears to us as a distinct colour, it becomes probable that these ultra-violet rays must make themselves apparent to the ants as a distinct and separate colour (of which we can form no idea), but as different from the rest as red is from yellow or green from violet.
Seite 284 - If blue is the favourite colour of bees, and if bees have so much to do with the origin of flowers, how is it that there are so few blue ones ? I believe the explanation to be that all blue flowers have descended from ancestors in which the flowers were green; or, to speak more precisely, in which the leaves surrounding the stamens and pistil were green; and that they have passed through stages of white or yellow, and generally red, before becoming blue.
Seite 282 - I then put them on a lawn, in a row, about a foot apart, and on each put a second slip of glass with a drop of honey. I also put with them a slip of plain glass with a similar drop of honey.
