Great blocks of that basalt, which, according to Bischof, takes three hundred and fifty millions of years to cool, strewed the plain, very confused in some places. However, there were here no traces of lava, which was spread more particularly over the northern slopes.
Professor Bischof has shown what changes may be superinduced, on black marble and other rocks, by the steam of a hot spring having a temperature of no more than 133 degrees to 167 degrees Fahrenheit, and we are becoming more and more acquainted with the prominent part which water is playing in distributing the heat of the interior through mountain masses of incumbent strata, and of introducing into them various mineral elements in a fluid or gaseous state.
But this process of segmentation, though in these animals it leads to such a multiplication of individuals, is exactly the same as that discovered by K.E. von Baer in the egg of the Frog, and described and figured by Professor Bischof in the egg of the Rabbit, the Dog, the Guinea-Pig, and the Deer, while other embryologists have traced the same process in Birds, Reptiles, and Fishes, as well as in a variety of Articulates, Mollusks, and Radiates.
The rehearsals had been superintended by the emperor in person; he had suggested and directed the scenery and decorations, and, to the great scandal of his confessor, Father Bischof, Leopold had more than once curtailed his devotions, to attend these rehearsals.
Young, by his munificent bequest of £10,000 for the foundation of a Chair of Technical Chemistry, established a connection between the scientific chemist and the workshop. The first occupant of the chair, Herr Bischof, commenced his duties during last summer, and the number of students attending his class has already exceeded all expectations.
You are as glorious as the god of day; and if the Muses were to trip by, they would surely mistake you for their Phoebus, and, quitting Parnassus, make themselves at home in Vienna." "And be driven away with contumely; for, being heathen maidens, Father Bischof would speedily exorcise and exile them back to Greece. And now tell me what you think of the new opera.
A highly interesting and instructive experiment, showing how gold might be, and probably was, deposited in quartz veins, was carried out by Professor Bischof some years ago.
In the higher animals these changes are extremely complicated; but, within the last half century, the labours of such men as Von Baer, Rathke, Reichert, Bischof, and Remak, have almost completely unravelled them, so that the successive stages of development which are exhibited by a Dog, for example, are now as well known to the embryologist as are the steps of the metamorphosis of the silkworm moth to the school-boy.
