Agriculture of New York; comprising an account of the classification, composition and distribution of the soils and rocks and the natural waters of the different geological formations, together with a condensed view of the meteorology and agricultural productions of the State.
Page 259 - Lamarck, and so it is, as it exists in the country ; but in the city it is sometimes two inches in length, when not fully extended, and of a corresponding bulk. The dark lines are most strongly marked in the large variety. The small variety is more delicate in its markings, and has a tinge of yellow on the foot. It is still restricted in its distribution, so far as known, to the neighborhood of Boston alone.
Page ix - They vary from yellowish-green through horn color to chestnut, most of them being simply horn-colored. This is perhaps owing to the fact that our species do not infest our gardens and open fields, but are generally confined to forests, sheltered under logs and stones, and are rarely seen abroad except during twilight or on damp and dark days ; indeed, they almost entirely disappear as the forests are cut down, and seem to flee the approach of man. The European species, on the other hand, follow in...
Page 95 - H. puttula and //. leporina, — is less globose than the former, and more sparingly hirsute. It differs widely from both in the character of the umbilicus, — the aperture is much like that of pustula, but more narrow than that of leporina.

Page xi - So, also, when they are surrounded by a corrosive gas, or are thrown into water or alcohol, they form over themselves in this way a thick protecting covering, which is undoubtedly a nonconductor of heat and impervious, at least for a time, to liquids. Shielded by this coating, they can live the greater part of a day immersed in water, and for a shorter time in alcohol ; and M. Fe'russac asserts that they have survived for hours in boiling water. They leave a trace of their usual secretion on every...
Page 49 - Bouchard-Chantereaux has observed them to deposit eggs in sixty-six days after their own birth, and to attain their full size in eighty-two days. This species varies very much in color, and the descriptions by different authors, being drawn principally from it, differ greatly from each other ; but whatever may be the color, the peculiar character of the furrows and the tubercles remains constant. In a state of contraction the back is arched ; the head is entirely withdrawn under the mantle ; the...
Page 157 - Two submarginal cells ; four posterior cells ; a discal cell ; the second longitudinal vein originates, at a more or less acute angle, before the middle of the length of the wing and a considerable distance (more than the breadth of the wing) before the tip of the auxiliary vein ; the subcostal cross-vein is at a considerable distance (three lengths of the great cross-vein, or more) from the tip of the auxiliary vein ; seventh longitudinal vein straight.
Page 79 - Shell broadly nmbiliuated, dopressed-globose, rather solid, white, shining, ribbed above, smoother below ; spire obtuse, little elevated, rounded ; whirls seven, convex, the upper ones more flattened, the last bluntly carinated ; carina not reaching the peristome ; base parallel to the suture ; umbilicus broad, half the larger diameter of the shell, showing two and a half deeply grooved...
