Seite 4 - SIR: I have the honor to submit herewith and to recommend for publication as a Farmers' Bulletin a report on Pheasant Raising in the United States, by Henry Oldys, assistant in the Biological Survey.
Seite 50 - Some of the smaller plankton organisms have probably a worldwide range. In such a limited area as Scotland, it would not, then, be surprising if there were no important variation of the plankton over the whole country. This is far from being the case. The plankton of the extreme north differs greatly from that of the south ; that of the west from that of the east. Scotland appears to be favourably situated for the study of fresh-water plankton, as from its geographical position it forms a meeting...
Seite 7 - When there has been no reason to suppose that the trawl has sunk more than one or two inches in the clay, we have had in the bag over a hundred sharks...
Seite 17 - If the necessary precautions have been taken, most amebas, as they multiply, will quite generally spread rapidly over the plate, and in passing through the rings of growing bacteria they will lose the organisms with which they started and take up those forming the rings. In from twenty-four to seventy-two hours the protozoa will have passed one or more of the rings, and from such locations they may be taken for transplanting. It sometimes happens that they appear on the first plate in pure cultures...
Seite 8 - Bag over a hundred shark's teeth and between thirty and forty ear-bones of cetaceans ; some of them have been imbedded in over an inch of the Manganese arranged in concentric layers, while others have had just a trace of Manganese on them, or none at all. ... In the...
Seite 7 - The jelly-like aspect and the matter coloured with carmine can always be removed from the spirifcpreserved specimens of the ooze by treating with distilled water. In all cases the jelly-like or mobile aspect of the oozes is found to be due to the presence of the flocculent precipitate from the seawater associated with the ooze. No free albuminous matter could be detected...
Seite 48 - It thus appears that the most favorable conditions for lime-secreting organisms are met with in the warm, equable tropical waters of the ocean, and here, as a matter of fact, we find the greatest development of corals and the largest number of lime-secreting pelagic organisms. In the polar areas and in the cold water of the deep sea there is, as Is well known, a feeble development of all carbonate of lime structures in marine organisms.
Seite 8 - Eadiolarian, and Diatom oozes we have found during the whole cruise only one or two shark's teeth and perhaps one tympanic bone. In shore-deposits they were even more rare. These facts, taken with others that will at once suggest themselves, go to show, as might be expected, that the shore-deposits accumulate faster than the organic oozes, and these last faster than the deep-sea clay. The organisms in our Eadiolarian ooze appear to resemble very closely and in their relative proportions those described...
