Page 200 - THE sun, the moon, the stars, the seas, the hills and the plains — Are not these, O Soul, the Vision of Him who reigns ? Is not the Vision He ? tho' He be not that which He seems? Dreams are true while they last, and do we not live in dreams ? Earth, these solid stars, this weight of body and limb, Are they not sign and symbol of thy division from Him...
Page 284 - ... through these tubes at a rate sufficiently slow to dry it, and to remove its carbonic acid, carried into the experimental tube a considerable amount of mechanically suspended matter, which was illuminated when the beam passed through the tube. The effect was substantially the same when the air was permitted to bubble through the liquid acid and through the solution of potash.
Page 267 - ... suitable fluids, even in the course of a few hours. Observations upon the organic particles of respired air had at different times been made by the author. 1. In 1857 glass plates covered with glycerine had been exposed in different places and examined microscopically. Amongst others in the dome of the Borough Gaol, to which all the respired air in the building is conducted, organized particles from the lungs and various fibres were found in this air. 2. During a crowded meeting at the Free Trade...
Page 267 - ... abundant specimens of a small-celled torula were found, and these were seen to increase in numbers for two days, after which they ceased to develop. These differences in the nature of the bodies met with probably show some difference in the nature of the fluid given off ; but it was pointed out that they afford no proof as yet of the germ theory of disease.
Page 268 - The mycelia of these minute fungi were similar to that of rust or mildew (as it is commonly named), such as is found on straw or decaying vegetation. When the bottle had remained for 36 hours in a room at a temperature of 60°, the quantity of fungi had visibly increased, and the delicate mycelial thread-like roots had completely entangled the fibrous objects contained in the bottle and formed them into a mass.
Page 114 - They both may lay equal claim to the word Reformation; the one having compassed it in Religion, the other purposing it in Philosophy. They both have taken a like course to bring this about; each of them passing by the corrupt copies, and referring themselves to the perfect Originals for their instruction; the one to the Scripture, the other to the huge Volume of Creatures.
Page 317 - Sigillaria eleyans illustrated by Brongniart, probably represented other types of Sigillarioid trees, and it is not improbable that the genus Sigillaria, as usually understood, really includes several distinct generic forms. The author had recognized six generic forms in a previous paper, and in his
Page 93 - ... plants these spines are replaced by tubercles, and both spines and tubercles vary greatly in length and number ; for example, in Valeriana tuberosa the spines are only half the length of those on the pollen of V. montana, the grains being also slightly smaller. The pollen of the...
Page 94 - ... markings which are met with on their surface after the grains have collapsed by the discharge of their contents. In regard to the mounting of these objects for the microscope, they show to the best advantage when put up perfectly dry ; the cells should be sufficiently shallow to admit of no more than a single layer, and at the same time deep enough to permit the grains to move about. If pollen is mounted soon after it has been discharged from the fresh anthers the fovilla is apt to condense on...
Page 93 - R. hirsutut, their dimensions being respectively -j-ygth and -j^-Rth of an inch. I have not had the time to make similar careful measurements with the micrometer, but I have seen sufficient to be satisfied that while there is considerable variation in dimensions between the pollen of one species and that of another, they are tolerably constant in size in the same species. For some noticeable differences compare the smaller pollen of Epilobium brachycarpvm with the larger pollen of E.
