"Microscopical" Quotes from Famous Books



... of the 6th February, complains that the coal supplied by the Authorities for barrack-rooms, is so limited in quantity that "during the winter this, as a rule, only lasts about two days" in the week, and TOMMY and his comrades have to "club-up" to supply the deficiency out of their own microscopical pay. "In fact" (says T.A.) "I have been in barrack-rooms where the men have had no fires after the first two days of the week." If this be so, Mr. Punch agrees with TOMMY in saying, "Surely this ought not to be!" TOMMY ATKINS may reasonably ...

... red, green, and violet. We are, however, absolutely ignorant how we perceive these colours. Thomas Young suggested that we have three different systems of nerve fibres, and Helmholtz regards this as "a not improbable supposition"; but so far as microscopical examination is concerned, there is no evidence ...

... general resemblance to the slags and clinkers which are formed in our furnaces and brick-kilns, and consist, like them, of various stony substances which have been more or less perfectly fused. When we come to study the chemical composition and the microscopical structure of lavas, however, we shall find that there are many respects in which they differ entirely from these artificial products, they consisting chiefly of felspar, or of this substance in association with augite or hornblende. In texture they may be stony, glassy, resin-like, ...

... pairs, seated in two approximate rows; the middle filaments are the longest, equalling about half the diameter of the thorax: each is flattened, and tapers but little towards its summit, which is roughened with microscopical crests serrated on both sides; on the summit, also, there are a few bristles and some very short, thick, minute spines. These appendages are directed rather towards each other, and towards the thorax. I do not doubt that their numbers vary according to the size of the specimen. I believe that ...

... history of the disease indicated a general blood infection. As my equipment included the best microscopical apparatus made, I had strong hopes that in properly stained preparations of blood taken from the circulation of yellow fever patients my Zeiss 1-18 oil immersion objective would reveal to me the germ I was in search of. But I was doomed to disappointment. ...

... make my preaching effective and helpful I studied unweariedly and took up astronomy, buying a three inch telescope, and soon became elected to Fellowship in the Royal Astronomical Society of England. Then I took up microscopy, buying the fine microscope from Dr. Dallinger, President of the Royal Microscopical Society, with which he had done his great work on bacilli—and which, by-the-way, was later stolen from me—and I was speedily elected a Fellow of that distinguished Society. A little later Joseph Le Conte, ...

... this power of altering their specific gravity possess a mechanism for raising themselves to the top of the water, or lowering themselves to the bottom at will. They use this not only in the abnormal circumstances of their being under microscopical observation, but at all times, as may be known by our being always able to find some specimens with air-bladders at the top of the water in ...

... and the period of maturity. When sterility is induced by domestication it is of the same kind, and varies in degree, exactly as with hybrids: for be it remembered that the most sterile hybrid is no way monstrous; its organs are perfect, but they do not act, and minute microscopical investigations show that they are in the same state as those of pure species in the intervals of the breeding season. The defective pollen in the cases above alluded to precisely resembles that of ...

... said, "with this tiny machine concealed in my waistcoat pocket, I walk up to any man and, by turning a screw like the stem of a watch, open the microscopical receiver. Into the receiver flow all psychical emanations from that unsuspicious citizen. The machine is charged, positively. Then I saunter up to some man, place the instrument on a table—like that—touch a lever. Do you see that hair wire of Rosium uncoil like a tentacle? It is searching, ...

... of my knowledge the subject was taken up in 1818, by my lamented friend the late Mr. Thomas Smith, who, eminently qualified for an investigation where minute accuracy and great experience in microscopical observation were necessary, succeeded in ascertaining the very general existence of the foramen in the membranes of the Ovulum. But as the foramina in these membranes invariably correspond both with each ...

... claim to fame that he contrived a form of novel which exhibited an ordinary mind working in normal circumstances, and that he did this with a minuteness which till then had never been thought of and has not since been surpassed. His talent is very exactly a microscopical talent; under it the common stuff of life separated from its surroundings and magnified beyond previous knowledge, yields strange and new and deeply interesting sights. He carried into the study of character which had begun in ...

... or entomostraca, of which the rivers and ponds are full, and which are the main food of the smaller water carnivora, live mainly on decaying vegetable substance, which is practically converted and condensed into microscopical animals before these become in turn the food of others. It is as if all trees and grass on land were first eaten by locusts or white ants, and the locusts and white ants were then eaten by semi-carnivorous cows and sheep, which were in turn eaten by true carnivora. The water-weeds, ...

... be misled by popular statements in this connection, such as this of Professor Owen's: "There are organisms which we can devitalize and revitalize—devive and revive—many times." (Monthly Microscopical Journal, May, 1869, p. 294.) The reference is of course to the extraordinary capacity for resuscitation possessed by many of the Protozoa and other ...

... appearances being so wholly different. And perhaps such a quickness and tenderness of sight could not endure bright sunshine, or so much as open daylight; nor take in but a very small part of any object at once, and that too only at a very near distance. And if by the help of such MICROSCOPICAL EYES (if I may so call them) a man could penetrate further than ordinary into the secret composition and radical texture of bodies, he would not make any great advantage by the change, if such an acute sight would not serve to conduct him to the market and exchange; if he could not see things ...

... beautiful, often coloured, sporidia. These latter have either a smooth, warted, spinulose, or lacunose epispore, and, as will be seen from the figures in Tulasne's Monograph,[v] or those in the last volume of Corda's great work,[w] are attractive microscopical objects. In some cases, it is not difficult to detect paraphyses, but in others they would seem to be entirely absent. A comparatively large number have been discovered and recorded in Great Britain,[x] but of those none are more ...

... way of maps, but this is a fault of all Guides. Wishing, when at Havre, to visit Merville-sur-Mer, and the celebrated Corneville, with whose cloches we are all acquainted, in vain I searched the ordinary maps, and at last found quite a microscopical place, and without the "Sur Mer," as there wasn't room for it in a map of either the Guide Joanne or Conty, I forget which. Why it seems to be generally ignored I don't know, but in this respect it is a fellow-sufferer ...

... disease was believed to have originated from a perineal fistula. The pathological investigation in the case, however, by Mr. Quekett, who submitted the mass to a microscopical examination, confirmed Mr. Brett in his original opinion that the disease had the same pathological conditions as the similar disease found in India, where it originates from local inflammatory causes. In this case the preputial irritation was, in all probability, the precursor of ...

... and the body filled in like manner with aromatic spices. When all was finished, the corpse was left 70 days in a solution of soda, and then wrapped in bandages of byssus spread over with gum. The microscopical examinations of mummy-bandages made by Dr. Ure and Prof. Czermak have proved that byssus is linen, not cotton. The manner of embalming just described is the most expensive, and the latest chemical researches prove that the description given of it by the Greeks was tolerably correct. L. ...

... de Ch. et de Physique, ser. iv., vii., 181).—This form of prism was devised in 1866 by MM. Hartnack and Prazmowiski; the original memoir is a valuable one; a translation of it, with some additions, has lately been published (Journ. of the R. Microscopical Soc., June, 1883, 428). It is considered by Dr. Feussner to be the most perfect prism capable of being prepared from calc-spar. The ends of the prism are perpendicular to its length; the section carried through it is in a plane perpendicular to the principal axis of the crystal. The cementing medium ...

Compare, for instance, the mossy and viscid calyx of a moss-rose, which suddenly appears through bud-variation on a Provence-rose, with the gall of red moss growing from the inoculated leaf of a wild rose, with each filament symmetrically branched like a microscopical spruce-fir, bearing a glandular tip and secreting odoriferous gummy matter.[708] Or compare, on the one hand, the fruit of the peach, with its hairy skin, fleshy covering, hard shell and kernel, and on the other hand one of ...
