Natural history, properly so called, or the study of the origin and past history of the universe, the earth, and its organic population, is much more recent than the history of mankind.

It is now well known that the outer covering of the so-called sea-squirts or Ascidian Mollusks contains a large quantity of cellulose (as much as 60 per cent.

in some cases); and recent researches seem to prove that this substance is present also in some of the lower forms of animal life (coccospheres). * Recent researches, especially those of Dr Bastian, have established Page 39 ORIGIN OF SPECIES.

39 I3. ORIGIN OF SPECIES. It is impossible here to do more than merely indicate in the briefest manner the two fundamental ideas which are at the bottom of all the various theories as to the origin of species. In former times the Puma inhabited nearly the whole American continent, from Canada to Patagonia, but it is now extirpated in many places, especially in North {19} America.

It was formerly supposed that the Puma could not be tamed; but this is incorrect, as the late Edmund Kean, the tragedian, had one which followed him about like a dog, and. Full text of "A treatise on the practice of medicine, for the use of students and practioners" See other formats.

This minuter study had two origins, one in the researches of the medical anatomists, such as Fabricius (–), Severinus (–), Harvey (–), and Tyson (–), the other in the careful work of the entomologists and first microscopists, such as Malpighi (–), Swammerdam (–), and Hook (–).

[at first meeting of session, 6 Oct, Dr. Webster delivered a paper, "Observations of the Health of the Metropolis during the last six months, more especially in reference to the recent epidemic of cholera." Mention is made of pure water (but not JS's hypothesis) and of the fungi theory of Brittan.

Comment by Lankester; none by JS.]. The principal Cestode of ruminants is Tenia expansa, which, when fully mature, is more frequently found in sheep than in cattle.

Its body consists of about one thousand segments, each more broad than long. It is the longest of all tape-worms, being (according to Cobbold) in sheep from 8 to 30 feet and in oxen from 40 to feet in length.

Which have a shell like an elongated cone, arched, open at the two ends, and which has been compared to an elephant's tusk in miniature. But the recent observations of M. Savigny, and especially of M.

Deshayes, render this classification very doubtful. See " Monographic du Genre Dentale, Mem. de la Soc. d'Hist.

Nat. de Paris," t. Origin of the Paired Fins.—The question of the origin of the paired fins is much more difficult and is still far from settled, although many, perhaps the majority of recent writers favor the theory that these fins are parts of a once continuous lateral fold of skin, corresponding to the vertical fold which forms the dorsal, anal, and caudal.

The Bandwürmer and the Blasenwürmer would eventually be combined to form the cestodes, but this division by Zeder inhibite d realization that the two groups were related, and more than 50 years were t o pass before the relationship was proven with the recognition that cystic worms were intermediate stages in the life cycles of tape worms.5/5(1).

The origin of the disease is ascribed to the ingestion of vegetable food, especially certain cereals (barley). The avenue of entrance in man bespeaks the same origin, that is, some vegetable source.

Symptoms.—The disease demonstrates itself as a torpid and but slightly painful growth, which finally perforates the skin with sin- uous tracts. The Societys Index Expurgatorius would have been more complete, if it had included the Invocation of the third book of Paradise Lost, which has hitherto escaped the Anglican censorship.
