470 페이지 - It is near six inches in length from the tip of the bill to the end of the tail, the former being about half an inch, and the latter two inches and a half.
259 페이지 - The plan is essentially as follows : — Behind the objective, and as near thereto as practicable, the light is equally divided, and bent at right angles and made to travel in opposite directions, by means of two rectangular prisms, which are in contact by their edges, that are somewhat ground away. The reflected rays are received at a proper distance for binocular vision upon two other rectangular prisms...
341 페이지 - First. Toads deposit spawn in cellars and young toads are afterwards observed. Last summer several masses of spawn were procured from my cellar, having been found deposited amongst decaying potatoes, &c., and subsequently young toads were noticed. The cellar is free from water, and at a considerable distance from any brook.
342 페이지 - Young frogs dug out of the ground in the month of January. In digging in the garden amongst the strawberry-beds (near where so many toads were observed last summer) in the middle of January in the present year, a nest of about a score young frogs were upturned. These were apparently three or four weeks old. This ground had been previously dug in the month of August and many strawberry plants buried ; it was amongst a mass of these plants in a state of partial decomposition that these young ones were...
342 페이지 - It seems probable from the above, that frogs are occasionally born alive in situations where no water can be found for the spawn to be deposited in, and that toads are either reproduced in the same manner, or from the egg directly. The latter mode seems most likely, owing to spawn having been found previously to the young toads. Mr. Higginbottom tells me, the same remark on the birth of the Triton, without the stage of tadpole, has been mentioned to him. These are the facts ; should the subject be...
319 페이지 - Nesodon magnus, is satisfactorily indicated by a grinder of the upper jaw. In conclusion, the author remarks, that the osteological characters defining the orders of hoofed quadrupeds, called Proboscidia, Perissodactyla and Artiodactyla, are associated with modifications of the soft parts of such importance, as not only to establish the principle of that ternary division of the great natural group of Ungulata, but to indicate that the known modifications of the skeleton of the extinct Toxodons and...
259 페이지 - ... somewhat ground away. The reflected rays are received at a proper distance for binocular vision upon two other rectangular prisms, and again bent at right angles, being thus either completely inverted, for an inverted microscope, or restored to their original direction.
242 페이지 - ... there, high over the heath, wings his meandering way the joyous Snipe, giddy with excess of unalloyed happiness. There another has sprung from among the yellow-flowered marigolds that profusely cover the marsh. Upwards slantingly, on rapidly vibrating wings, he shoots, uttering the while his shrill two-noted cry. Tissick, tissick, quoth the Snipe, as he leaves the bog. Now in silence he wends his way, until at length having reached the height of perhaps a thousand feet, he zigzags along, emitting...
246 페이지 - Ireland,' vol. ii. Birds, by W. Thompson, it is stated, as a reason for the Golden Pheasant not doing well in a wild state in this country if introduced where the common pheasant is now abundant, that they are such a shy, timid bird, and would be easily driven off by the other species. This fear is evidently groundless, as not only the half-bred birds, but the golden hen drove all the other pheasants, as was seen frequently by the keeper ; and they were so cunning, and so well able to take care of...
410 페이지 - The differences between the two kingdoms are, mainly : 1. That in the plant the endoplast grows, and, as the primordial utricle, attains a large comparative size: — while in the animal the endoplast remains small, the principal bulk of its tissues being formed by the periplastic substance ;' and, 2. In the nature of the chemical changes which take place in the periplastic substance in each case. This distinction, however, does not always hold good, the Ascidians furnishing examples of animals whose...
