253 페이지 - This very interesting specimen, submitted to me for examination by Sir. WE Logan, is, in my opinion, of great importance, as furnishing a conclusive answer to all those objections to the organic nature of Eozoon which have been founded on comparisons of its structures with the forms of fibrous, dendritic, or concretionary minerals, — objections which, however plausible in the case of highly crystalline rocks, in which organic remains may be simulated by merely mineral appearances readily confounded...

lxv 페이지 - These observations bring the formation of silicious minerals face to face with life, and show that their generation was not incompatible with the contemporaneous existence and the preservation of organic forms. They confirm, moreover, the view which I some years since put forward, that these silicated minerals have been formed, not by subsequent metamorphism in deeply buried sediments, but by reactions going on at the earth's surface...

Higher productivity growth and technological innovation will generate more resources for financing industrial restructuring and vocational retraining, thereby increasing political support for economic liberalization. At the same time, it is of the utmost importance to bear in mind that there is no single optimal policy stance that is applicable to all countries at all levels of development. A simple replication of policies that...
106 페이지 - As a contribution to the evidence on the geological position of the blocks of saccharoid sandstone scattered on the surface of many parts of the chalk-districts, I beg to lay before the Society a brief account of the occurrence of similar blocks of large size in the Drift of Suffolk, both in situ and on the surface.
lxiv 페이지 - In conclusion, the author showed that the various silicates already mentioned were directly deposited in waters in the midst of which the Eozoo'n was still growing or had only recently perished, and that they penetrated, enclosed, and preserved the structure of the organisms precisely as carbonate of lime might have done ; and he cites these and other facts in support of his opinion that these silicated minerals were formed, not by subsequent rnetamorphism in deeply buried sediments, but by reactions...
256 페이지 - In a few places a tubulated cell wall is preserved, with structure similar to that of Eozoon Canadense. Specimens of Laurentian limestone from Wentworth, in the collection of the Geological Survey, exhibit many rounded siliceous bodies, some of which are apparently grains of sand, or small pebbles ; but others, especially when freed from the calcareous matter by a dilute acid, appear as rounded bodies, with rough surfaces, either separate or aggregated in lines or groups, and having minute vermicular...
