Book excerpt: Excerpt from The American Monthly Microscopical Journal, Vol. 12: Containing Contributions to Biology, for 1891 Nor do the valves separate along the raphe or median line, but along the line of junction or suture. If the reader will turn over a page or two to the conspectus, he will see it stated by H. L. Smith, of Tribe I, Raphidieae, for example: "Frustules, mostly bacillar in s. v., always with a distinct raphe on one or both valves." (Italics mine.) Thus the two statements do not agree, and that on p. x will be likely to give the student a very different idea of what is meant by the raphe. But to return to our article. The trouble has all come, in my opinion, from calling the inner portion of the valve a hoop at all. For it suggests at once a barrel-hoop, something which is free at both edges from that which it encloses; which is not usually the case with the diatom hoop, to say the least. It is a misleading term, and is bound to confuse the student. It would be much better, therefore, it seems to me, to drop it altogether, or to speak of this piece as that portion of the membrane of each valve which when separated from the valve has the shape of a hoop. For as long as it is attached to the valve it is not a hoop, but the continuation of the valve itself. Finding this portion, however, at times detached, and shaped like a hoop, observers have thought there was only one hoop to each frustule, and that it bound the two valves together, whereas the truth is that there is a so-called hoop to each valve, and the hoops found in settlings of the Diatomaceae did not come each from a frustule but each from a valve, that is, two from each frustule. (There may be a few exceptions, but in my opinion the above will hold as a general statement.) Now, I am inclined to believe that very few amateurs have had the occular demonstration of this fact. Having to write upon the subject, and finding it impossible to reconcile the figures with what Carpenter said, I went to my slides again, and with the binocular, and almost the first peep at Isthmia showed me that the drawings were faulty in representing the upper and lower edges of the two valves as continuous lines instead of broken ones. And then I took down Schmidt's plates and the whole thing was as clear as day. And my advice to the student is to do the same thing: to pick out all his slides of Isthmia, Biddulphia, and Triceratium, and using the binocular, look sharp at the upper and lower edges of the hoop, and he will soon see that each is not one continuous line, but is formed by two lines, one of which is inside the other. And then if he is fortunate he will find some frustules where the valves have partly separated, and he will find that each valve has its band or hoop, and that it forms one continuous piece with the valve. And when he has done this he will have done something that is better than resolving Amphipleura, for he will have gained a definite idea of the structure of the diatom frustule. And this is a point that cannot be too strongly insisted upon, since even the Micrographic Dictionary has gone through edition after edition without stating or figuring the matter correctly. The first thing then for the student to do is to get a correct idea of the way the two valves are put together, and to do this he must not rely upon the figures in the Micrographic or in Carpenter, but study carefully the actual diatoms with the binocular.

Book excerpt: Excerpt from The American Monthly Microscopical Journal, 1897, Vol. 18: Containing Contributions to Biology While the idea of the arrangement in the experiment below detailed is suggested from a study of the Abbe form of apertometer, it is essentially different in half the technique. For the benefit of those who are not familiar with the instrument and in the hope that I may make the proposed modification plainer, it may not be amiss to attempt a short explanation of its working, particularly as this is not done in the Zeiss catalogue. It consists essentially of (a) an auxiliary objective and (b) the plate glass semicircular and prismatic disc.

This book was released on 1995-08-24 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridging the fields of conservation, art history, and museum curating, this volume contains the principal papers from an international symposium titled "Historical Painting Techniques, Materials, and Studio Practice" at the University of Leiden in Amsterdam, Netherlands, from June 26 to 29, 1995. The symposium—designed for art historians, conservators, conservation scientists, and museum curators worldwide—was organized by the Department of Art History at the University of Leiden and the Art History Department of the Central Research Laboratory for Objects of Art and Science in Amsterdam. Twenty-five contributors representing museums and conservation institutions throughout the world provide recent research on historical painting techniques, including wall painting and polychrome sculpture. Topics cover the latest art historical research and scientific analyses of original techniques and materials, as well as historical sources, such as medieval treatises and descriptions of painting techniques in historical literature. Chapters include the painting methods of Rembrandt and Vermeer, Dutch 17th-century landscape painting, wall paintings in English churches, Chinese paintings on paper and canvas, and Tibetan thangkas. Color plates and black-and-white photographs illustrate works from the Middle Ages to the 20th century.

Download or read book Diatoms written by F. E. Round and published by Cambridge University Press. This book was released on 2007-12-04 with total page 1208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a wide-ranging introduction to the diatoms together with an illustrated description of over 250 genera. Diatoms are important as perhaps the commonest group of autotrophic plants on earth and are abundant in all waters and on soils and moist surfaces. The introduction describes the diatom cell in detail, the structure of the wall (often extremely beautiful in design), the cell contents and aspects of life cycle and cell division. The generic atlas section is the first account of diatom systematics since 1928 (Karsten in Engler and Prantl: Die Nauturlichen Pflanzenfamilien) and each generic description is accompanied by scanning electron micrographs to show the characteristic structure. Most of the latter have been prepared specially for this work from the authors' own collections. The Diatoms will be the standard reference work on the group for years to come and is an essential reference volume.
