Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1899, Vol. 41 On both sides of the Atlantic, latitude 40 N. marks approximately the southern limit of Arenicola marina. South of this it is replaced in the Mediterranean by A. Claparedii, Lev., and by A. cristata, Stimps., the latter also ranging on the west side of the Atlantic from Cape May (N. J.) to the Caribbean Sea. Its reputed occurrence on the north coast of Alaska (Murdoch), at Vancouver Island (Marenzeller, 1887), Coquimbo, and South Africa requires confirmation. An abundant, widely ranging, and undoubtedly old form such as Arenicola, might be expected to vary considerably in its habits and structure, though it has not hitherto been ascertained how far this is the case. Having paid special attention to this point, we have found that there are (at least on the Lancashire coast) two varieties of A. marina, differing in habits, structure, and times of maturity, and that there is, in addition, considerable individual variability. (1) From high-water mark down to the beginning of the Laminarian zone, the common shore lugworms (or "lugs," as fishermen call them, in contradistinction to the second variety, or "worms") sink their U-shaped burrows to a depth of from one to two feet below the surface. One end of the burrow is marked by a casting, the other by a "countersunk" hole, through which the head of the lugworm is protruded when the tide comes in. The size and colour of the animal vary with the amount of muddy organic matter in the sand. Where there is comparatively little mud, the Arenicola average about seven inches in length and are somewhat transparent, so that the superficial blood-vessels can be clearly seen through the thin body-wall. The gills, which are not very strongly developed, are composed of nine to eleven branches, each provided with three to five pairs of short lateral twigs (Pl. 1, fig. 3). The proboscis and prostomium are only slightly pigmented, and being very vascular, appear red in colour. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

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, 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.

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, 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.

Book excerpt: Excerpt from Quarterly Journal of Microscopical Science, 1897, Vol. 39 The fact that the tint of the worm is due to contained blood, and not to any pigment in the skin, is readily recognised by the unaided eye when the alternating processes of eversion and retraction of the proboscis or introvert is watched. So long as the introvert is at rest within the body the thorax is coloured; when eversion takes place the tint becomes quite faint (pl. 1, fig. - in fact, frequently the thorax becomes white. The blood in the thorax is contained in greatly dilated vessels, which block up and obliterate nearly the whole of the coelom (fig. The introvert is a hollow sac traversed by thin bundles of retractor muscles, the cavity of the sac being con tinuous with the dilated vessels, so that on eversion nearly the whole of the blood in the thorax is driven into the introvert this flow of blood is, of course, the cause of the eversion, - and the thorax is more or less completely deprived of its colour. The fact that the abdomen is not tinted by the blood to any great degree is due to the small size of the blood-vessels in this region.
