Page 169 - ... surface of the sea, having a range of 125 fathoms, being more than twice the extent of all the other regions put together. Throughout this great, and I may say hitherto unknown province, for the notices we have had of it have been but few and fragmentary, we find an uniform and well-characterized fauna, distinguished from those of all the preceding regions by the presence of species peculiar to itself. Within itself the number of species and of individuals diminishes as we descend, pointing to...
Page vii - To give a stronger impulse and a more systematic direction to scientific inquiry, — to promote the intercourse of those who cultivate Science in different parts of the British Empire, with one another, and with foreign philosophers, — to obtain a more general attention to the objects of Science, and a removal of any disadvantages of a public kind which impede its progress.

Page 156 - Certain species in each are found in no other, several are found in one region which do not range into the next above, whilst they extend to that below, or vice versa. Certain species have their maximum of development in each zone, being most prolific in individuals in that zone in which is their maximum, and of which they may be regarded as especially characteristic. Mingled with the true natives of every zone are stragglers, owing their presence to the action of the secondary influences which modify...
Page 175 - Trochus is an example of a group of forms mostly presenting the most brilliant hues both of shell and animal; but whilst the animals of such species as inhabit the littoral zone are gaily chequered with many vivid hues, those of the greater depth, though their shells are almost as brightly coloured as the coverings of their allies nearer the surface, have their animals for the most part of an uniform yellow or reddish hue, or else entirely white. The chief cause of this increase of intensity of colour...
Page 94 - The advantages derived by the country from this establishment are almost incalculable ; for instance, the farmer who formerly rode and spent three days in making his market, can now do so in one for a few shillings, thereby saving two clear days, and the expense and use of his horse. The example of this institution has been generally followed, and cars innumerable leave the interior for the principal towns in the south of Ireland, which bring parties to and from markets at an enormous saving of time,...

Page 24 - The affinity of this alloy for iron is so intense, and the peculiar circumstances of surface induced by the preparing bath upon the iron presented to it are such, that care is requisite, lest, by too long an immersion, the plates or articles of iron should be partially dissolved; and where the articles to be covered are small, or their parts minute, it is necessary, before immersing them, to permit the alloy to dissolve or combine with some wrought iron, in order that its affinity for iron may be...
Page 175 - As the influence of the nature of sea-bottom determines in a great measure the species present on that bottom, the multiplication of individuals dependent on the rapid reproduction of successive generations of Mollusca, &c. will of itself change the ground and render it unfit for the continuation of life in that locality until a new layer of sedimentary matter, uncharged with living organic contents, deposited on the bed formed by the exuviae of the exhausted species, forms a fresh soil for similar...
