A simple direct vision Spectroscope by Baker, of High Holborn, was made use of, consisting of slit, collimator, and compound prism only. The instrument was usually made use of without a microscope. The position of the bands was determined by reference to the solar lines, matters being so arranged that half the field of View was occupied by the solar spectrum, whilst the other half showed the absorption spectrum to be determined. The following are the observations made on various colour ing matters. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1859, Vol. 7 During a recent voyage from India the success attending the use of certain appliances contrived by me for capturing such marine objects as came in our way, induces me to offer the subjoined account of them to the public. I may mention that, although familiar with the ordinary form of towing net and sounding apparatus, it struck me that much more might be done by resorting to some simple form of casting net, than is possible v.here the chapter of accidents is relied on for bringing within the jaws of the towing net the objects required, and by constructing some more portable sounding apparatus, which would at the same time prove effective at moderate depths, and bring up a much larger quantity of material than is attainable under the ordinary sounding lead, or the more complicated and cumbrous contrivance of Lieutenant Maury and others. I would further premise that whoever desires to make a collection of marine floating; molluses, tuniearies, ascidians, and the like, and also, the minuter organisms which exist in all latitudes in the open ocean, to a greater or lesser extent, will be grievously disappointed if he imagines that the trailing net used astern of a ship will suffice for the purpose. For, to be at all successful, constant and unremitting watchfulness is, in the first place, essential; and what is equally important, a fitting place of observation at the stern of the vessel, with ten or twelve feet of the water bend. In my own case, the quarter gallery of a 1500-ton merchantman afforded the best of all look-out ports; and from it I was enabled to use the casting net about to be described with ease and certainty. In the clear blue water of the open sea it is astonishing how rapidly the eye accustoms itself to detect creatures of the minutest size; and how readily it learns to distinguish, even in the small patches of calm water between each wave when a considerable sea is running, any object that may chance to be swimming near the surface. Nor is this confined to the portion of sea immediately below the observer, but it can be done at a distance of several yards.

Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1916, Vol. 61 The present research is now finished, and we have seen that the results obtained contradict the proposition put forward in my earlier paper upon this. Organism. I have carefully checked the measurements that led me to put forward this proposition, and have found them to be accurate; but the new evidence before us shows that it cannot be universal. In the circumstances, another negative proposi tion seems to have been established concerning the Spindle. We have found that it is not a figure formed entirely by the action of forces at its poles; we have found that its length at the conclusion of the metaphase is not proportional to the volume of the chromatin; and we have now found that the length at this stage is not proportional to the volume of the cell. We must, however, remember that these negative propositions have been established for individual cases, and are therefore generalisations only in that their antitheses cannot be put forward as being invariably valid.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, Vol. 8: With Illustrations on Wood and Stone Starch, from its physiological importance, remarkable structural peculiarities, and general diffusion through the vegetable kingdom, has been a favourite subject of investigation with physiologists and microscopists. However, not-withstanding the attention which has been devoted to its structure and development, it is acknowledged by the greatest physiologists to be known but little of. (See Mr. Busk's paper on "Starch Granules," in the number of the 'Quarterly Journal of Microscopical Science' for April, 1853.) There are, doubtless, intrinsic difficulties attending the investigation of this substance, but these have been very much augmented by the principle on which the examination has been conducted, namely, the cellular hypothesis. If this hypothesis had been in itself correct, and admissible as a basis of explanation of the facts connected with the structure and mode of formation of the starch granule, it ought, considering the amount of talent and ingenuity which have been employed in its application to these inquiries, to have thrown more light upon these much disputed, and as yet entirely unsettled questions. After this apology for thus differing from the high and almost universally credited authorities of the present day, I shall proceed to explain on a new principle - one strictly mechanical in its immediate operation - "the principle of molecular coalescence," - those points connected with the structure and development of starch granules, by which physiologists and botanists have been so long puzzled. In this paper the same train of reasoning will be employed, and the same experimental data adduced, as in my last paper, that on the "Structure and Mode of Formation of the Dental Tissues," as also in that on "Shell Structures;" and hence, though treating of a very different class of organized structures, this is still but an extension of my former researches.

Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1915, Vol. 60 The operculum is generally elongate or unguiform, and so small that it is useless for closing the mouth of the shell when the animal has withdrawn itself inside. The shells are covered with yellowish periostracum, which in some species is only a thin, smooth, transparent, but tough coating. In others, as in C. Tulip a, the periostracum is exceedingly thick and of a dark-brown colour. It is rough, furrowed longitudinally, and of a leather-like texture, and has tufts or outgrowths disposed in even rows along its surface. When dry, this thick periostracum becomes very brittle and peels OR the shell. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
