Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1892, Vol. 33 The curious phenomena preceding the maturity of the ovum in Metazoa have been the object of much study and the groundwork of much theory during the last fifteen years. Unfortunately processes occurring in this highly specialised group have been assumed to be typical of all organisms; the authors who have put forward explanations of what they have seen here have too often sought to extend these explanations to other groups, where the facts are different; they have created homologies where none such exist in Nature, and overlooked those which lay under their eyes. In this way protoplasmic changes of various origin and functions occurring in Protozoa, Protophytes, and Higher Plants, have been interpreted as excretory processes, in order to make them fit in with the replacement theories of fertilisation, founded almost exclusively on the formation of the polar bodies in the Metazoan ovum.

In the course of that period there are intervals during which the generative organs of all mammals exhibit, on the one hand special activity, and on the other hand a fallow condition. This variation is periodic, and is due, not to a periodic degeneration from a stable con dition, but to the periodic accession of a special stimulus, culminating in sexual desire, and resulting in coition and in gestation in the female when conception takes place.

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.

Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1923, Vol. 67 In the case of the upper jaw I was also able to trace the dental lamina to the very end, close to the condyle. It begins here as a much shorter fold than it becomes farther forward. The fold at the very first is more or less oval in transverse section, and later appears club-shaped. It becomes separated in fact into the oval free extremity and a much more slender stalk. The expanded free edge of the dental lamina may be traced forwards into the series of rudimentary teeth. The only change at first in this region of the dental lamina is the increase in size, at intervals and for the distance of a few sections, of the expanded free extremity. Nevertheless, it is particularly' to be noted that where there are no signs of tooth formation the ending of the lamina is still swollen. It has been asserted and denied1 that a swollen extremity of the dental lamina argues the actual presence of a rudimentary tooth germ. It would seem likely in the present case that the region of the jaw which we are now considering will ultimately be furnished with teeth. But I have no positive facts to fix the validity of this decision. And, moreover, in view of the apparent agreement in age of all the undoubted tooth germs in both jaws, it might be argued with equal force that the terminal region is not to be invaded by teeth. In this event the swelling of the edge of the dental lamina will be an argument in support of those who see in a terminal swelling no actual prophecy of teeth in the same situation, however rudimentary those teeth may be.

Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1856, Vol. 4: With Illustrations on Wood and Stone Few, if any, of the new species which have occurred, are confined to one locality; most of them have been found in several and these widely distant stations. These new species may be conveniently arranged in three sections: 1. Those already described by foreign naturalists, but now first detected as British forms. 2. Those which, although I have myself recognised them as entirely new forms, have been also, either about the same time or subsequently, observed by others. Although these are still unpublished ms. Species, and in many cases, my own observations were by much the earliest, yet as I find that these forms have been named by Mr. Smith, I adopt his names, to avoid the confu sion arising from synonyms. 3.

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.

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.
