LIX.--On Balaenoptera patachonica and B. intermedia. By Dr. H. Burmeister. An interesting acquisition is the skeleton of the whale met with in our river near the mouth of the Rio de Jujan during the month of August. Unfortunately the skeleton is not complete, owing to the negligence of the people who cleaned it provisionally; it wants the extreme point of the tail and the ends of both fins, which defect greatly diminishes its scientific value. The skeleton belongs to the species which I have described (Proc. Zool. Soc. 1865, p. 191) under the name of Balcmoptera patachonica, and completes our knowledge of that species, founded on an imperfect specimen, which showed some characters of importance--and proves, by its perfect identity with that specimen, that the other whale received last year (see Boletin, p. vii) does not belong to the same speci...

Excerpt from The Annals and Magazine of Natural History, 1863: Zoology, Botany, and Geology The physics of the development and of the life of the cell, as the basis of all anatomy and physiology, constitute the first problem to be solved in both those sciences. Since Schwann declared that both animal and vegetable tissues consist of cells originally of a like nature, the similarity also in function of such cells both in animals and plants has been rendered more and more evident. A clear perception of the whole of the physico-chemical phenomena which by their union constitute life will only be attained by an accurate knowledge of the origin and growth of the cell. The formative elements of the cells which unite to constitute organic tissues have been largely investigated since the time when Robert Brown indicated the presence of a nucleus in numerous cells, and since I demonstrated that the cell-wall, previously regarded as a single sac, consists in reality of several endogenous superimposed lamina; (Karsten, De Celia vitali, 1843).
