There can be little doubt, it seems to me, that this condition represents an early step in the direction of isogamy.

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.

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.

Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1901, Vol. 44 The bearing of young, however, is not possible at all times during the reproductive period. 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.

This book was released on 2018-01-29 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1861, Vol. 1 I will only here remark, on the propagation of the Dia tomaceae, that although it has not been shown that they form gonidia, yet I have reason to believe that gonidia, in the form of still or resting spores, are the sources from which the new crop originates on the beach each successive spring. This opinion I have formed from the following facts. First, amongst the myriads of specimens of marine Diatomaceae I have examined in the living state, I have never observed the process of conjugation. Secondly, I have, as a general rule, found the same species luxuriating in the same circum scribed locality (extending, in many cases, over only a few square yards) which yielded it in the previous summer. The presence of a particular form, year after year, in the same spot, would therefore appear to be due to the propagating cause, remaining buried in the sand during the winter, through the course of which not a diatom is to be found. Were the crop of each succeeding spring due to the subdivision of a single frustule, or of a few, accidently left by the tides, the same locality would prod, uce in all probability, widely different forms each returning season.
