For, inasmuch as the brain in all mammals completely fills the cranial cavity, it is obvious that a cast of the interior of the skull will reproduce the general form of the brain, at any rate with such minute and, for the present purpose, utterly unimportant differences as may result from the absence of the enveloping membranes of the brain in the dry skull.

Lartet, E., comparison of cranial capacities of skulls of recent and tertiary mammals; on the size of the brain in mammals; on Dryopithecus; on pre-historic flutes. Larus, seasonal change of plumage in. Larva, luminous, of a Brazilian beetle. Larynx, muscles of the, in songbirds. Lasiocampa quercus, attraction of males by the female; sexual difference of colour in.

Either through the intermingling of these two types or, as some prefer to think, by the direct prolongation of the original primitive man, a third intermediate type of human being appeared with hair and cranial measurement intermediate between the primitive Negro and Mongolian.

In the so-called "long-headed" or dolichocephalic races, the proportion is seventy-five to one hundred, while in those forms that have more rounded or brachycephalic heads, like the Polynesian and the black pygmy, the relation is eighty-three to one hundred. The cranial capacity again varies considerably, from nine hundred cubic centimeters to twenty-two hundred cubic centimeters.

"Besides, I feel that I'd like a little fresh air as a bracer, too, after such a shock." "What were those little cuts?" I asked as Waldon and Dr. Jermyn preceded us through the crowd outside to the pier. "Some one," he answered in a low tone, "has severed the pneumogastric nerves." "The pneumogastric nerves?" I repeated. "Yes, the vagus or wandering nerve, the so-called tenth cranial nerve.

Matrena noted the rosy freshness of his cheeks, the absence of down on his lip and not a hint of beard, the thick hair, with the curl over the forehead. Ah, that forehead the forehead was curious, with great over-hanging cranial lumps which moved above the deep arcade of the eye-sockets while the mouth was busy well, one would have said that Rouletabille had not eaten for a week.

The Scandinavians are certainly long-headed; but many Germans, the Swiss so far as they are Germanized, the Slavonians, the Fins, and the Turks, are short-headed. What were the cranial characters of the ancient "U-suns" and "Ting-lings" of the valley of the Yenisei is unknown.

Bell himself, meanwhile, had turned his attention to the cranial nerves, and had proved that these also are divisible into two sets sensory and motor. Sometimes, indeed, the two sets of filaments are combined into one nerve cord, but if traced to their origin these are found to arise from different brain centres.

The angle 'e f b'., or that made by the cranial with the facial axis, and which may be termed the 'cranio-facial angle, is extremely obtuse, amounting, in the case of the Beaver, to at least 150 degrees.

Prudden reports the case of a girl of twenty-five who, during convalescence from variola, became paraplegic, and during this time multiple neuromata appeared. At the postmortem more than a thousand tumors were found affecting not only the peripheral branches and the sympathetic, but also the cranial nerves and the pneumogastric.
