Page 186 - It was by him that goblets and brooches were first covered with gold and silver in Ireland.
Page 194 - The gold was found, accompanied by other metallic substances, dispersed through a kind of stratum composed of clay, sand, gravel, and fragments of rock, and covered by soil, which sometimes attained to a very considerable depth, from twenty to fifty feet, in the bed and banks of the different streams.
Page 80 - CE, in a paper read before the Institution of Civil Engineers of Ireland, as being very injurious to the timber piles of the jetty in Kingstown Harbour, near Dublin, and far more destructive than the Limnoria terebrans.
Page 108 - H in the ultra-violet region, which appear to belong to the spectrum of carbon (in some form) which I observed in the visible region of the spectra of telescopic comets in 1866 and 1868. There is also in the photograph a continuous spectrum in which the Fraunhofer lines can be seen. These show that this part of the comet's light was reflected solar light. This photographic evidence supports the results I obtained in 1868...

Page 37 - ... wider than the canal, and permitted the use of oars. All around us, so dense that not a ray of the sun could penetrate, was a forest of mangroves. These trees cover the low alluvions of the coast, which are overflowed by the tide, to the entire exclusion of all other vegetation. Their trunks commence at the height of eight or ten feet from the ground, and are supported by naked roots shooting downward and outward, like the legs of a tripod, hundreds in number, and those of one tree interlocking...
Page 195 - Numerous trials were made by driving and sinking on the veins previously known, and subsequently discovered. The mineral substances obtained, were subjected to the operations both of fire and of amalgamation: but in no instance was a particle of gold elicited from them, either by the one or the other operation.

Page 112 - Observations of Nebulae and Clusters of Stars made with the sixfoot and three-foot reflectors at Birr Castle from the year 1848 up to about the year 1878
Page 60 - Miller in 1863, simultaneously with Stokes, described his method of examining the photographic transparency of various saline solutions and organic substances and of depicting metallic spectra. A sensitised photographic plate •was used for the reception of the rays of the spectrum, so that they were made to register their own position and intensity. L. Soret invented the fluorescent eyepiece for the purpose of investigating the ultra-violet rays and ascertained the best media for the transmission...
