Our Conception Of A Compound Animal, Where In Some Respects The Individuality Of Each Is Not Completed, May Be Aided, By Reflecting On The Production Of Two Distinct Creatures By Bisecting A Single One With A Knife, Or Where Nature Herself Performs The Task Of Bisection.

We may consider the polypi in a zoophyte, or the buds in a tree, as cases where the division of the individual has not been completely effected.

Certainly in the case of trees, and judging from analogy in that of corallines, the individuals propagated by buds seem more intimately related to each other, than eggs or seeds are to their parents. It seems now pretty well established that plants propagated by buds all partake of a common duration of life; and it is familiar to every one, what singular and numerous peculiarities are transmitted with certainty, by buds, layers, and grafts, which by seminal propagation never or only casually reappear.

[1] The desserts of Syria are characterized, according to Volney (tom. i. p. 351), by woody bushes, numerous rats, gazelles and hares. In the landscape of Patagonia, the guanaco replaces the gazelle, and the agouti the hare.

[2] I noticed that several hours before any one of the condors died, all the lice, with which it was infested, crawled to the outside feathers. I was assured that this always happens.

[4] From accounts published since our voyage, and more especially from several interesting letters from Capt. Sulivan, R. N., employed on the survey, it appears that we took an exaggerated view of the badness of the climate on these islands. But when I reflect on the almost universal covering of peat, and on the fact of wheat seldom ripening here, I can hardly believe that the climate in summer is so fine and dry as it has lately been represented.

[5] Lesson's Zoology of the Voyage of the Coquille, tom. i. p. 168. All the early voyagers, and especially Bougainville, distinctly state that the wolf-like fox was the only native animal on the island. The distinction of the rabbit as a species, is taken from peculiarities in the fur, from the shape of the head, and from the shortness of the ears. I may here observe that the difference between the Irish and English hare rests upon nearly similar characters, only more strongly marked.

[6] I have reason, however, to suspect that there is a field- mouse. The common European rat and mouse have roamed far from the habitations of the settlers. The common hog has also run wild on one islet; all are of a black colour: the boars are very fierce, and have great trunks.

[7] The "culpeu" is the Canis Magellanicus brought home by Captain King from the Strait of Magellan. It is common in Chile.

[8] Pernety, Voyage aux Isles Malouines, p. 526.

[9] "Nous n'avons pas ete moins saisis d'etonnement a la vue de l'innombrable quantite de pierres de touts grandeurs, bouleversees les unes sur les autres, et cependent rangees, comme si elles avoient ete amoncelees negligemment pour remplir des ravins.
