Merrem sentence example

merrem
  • The following year Ranzani of Bologna, in his Elementi di zoologia - a very respectable compilation - came to treat of birds, and then followed to some extent the plan of De Blainville and Merrem (concerning which much more has to be said by and by), placing the Struthious birds in an Order by themselves.

  • Moreover, it veiled the honest attempts that were making both in France and Germany to find real grounds for establishing an improved state of things, and consequently the labours of De Blainville, Etienne, Geoffroy St-Hilaire and L'Herminier, of Merrem, Johannes Muller and Nitzsch-to say nothing of others-were almost wholly unknown on this side of the Channel, and even the value of the investigations of British ornithotomists of high merit, such as Macartney and Pvlacgillivray, was almost completely overlooked.

  • This scheme was the work of Blasius Merrem, who, in a communication to the Academy of Sciences of Berlin on the t oth December 1812, which was published in its Abhandlungen for the following year (pp. 237-259), set forth a Tentamen systematis naturalis avium, no less modestly entitled than modestly executed.

  • The attempt of Merrem must be regarded as the virtual starting-point of the latest efforts in Systematic Ornithology, and in that view its proposals deserve to be stated at length.

  • Without pledging ourselves to the acceptance of all its details - some of which, as is only natural, cannot be sustained with our present knowledge - it is certainly not too much to say that Merrem's merits are almost incomparably superior to those of any of his predecessors.

  • But Merrem, who subsequently communicated to the Academy of Berlin a more detailed memoir on the " flat-breasted " birds, 3 was careful not here to rest his divisions on the presence or absence of their sternal character alone.

  • The greatest benefit conferred by this memoir is probably that it stimulated the efforts, presently to be mentioned, of one of his pupils, and that it brought more distinctly into sight that other factor, originally discovered by Merrem, of which it now clearly became the duty of systematizers to take cognizance.

  • It is to be remarked, however, that the wealth of the Paris Museum, which he enjoyed to the full, placed him in a situation incomparably more favourable for arriving at results than that which was occupied by Merrem, to whom many of the most remarkable forms were wholly unknown, while L'Herminier had at his disposal examples of nearly every type then known to exist.

  • Instead of recognizing, as before, a subclass in the Ratitae of Merrem, Nitzsch now reduced them to the rank of an order under the name " Platysternae," placing them between the " Gallinaceae " and " Grallae," though admitting that in their pterylosis they differ from all other birds, in ways that he is at great pains to describe, in each of the four genera examined by him - Struthio, Rhea, Dromaeus and Casuarius.

  • Yet this distinguished zoologist selects the sternum as furnishing the key to his primary groups or " Orders " of the class, adopting, as Merrem had done long before, the same two divisions Cartnatae and Ratitae, naming, however, the former Tropidosternii and the latter Homalosternii.

  • These terms were explained in his great work L' Organisation du regne animal, oiseaux, begun in 1855, to mean exactly the same as those applied by Merrem to his two primary divisions.

  • There is no evidence, so far as we can see, of his having been aware of Merrem's views; but like that anatomist he without hesitation divided the class into, two great " coupes," to which he gave, however, no other names than " Oiseaux normaux " and" Oiseaux anomaux "-exactly corresponding with his predecessor's Carinatae and Ratitae-and, moreover, he had a great advantage in founding these groups, since he had discovered, apparently from his own investigations, that the mode of ossification in each was distinct; for hitherto the statement of there being five centres of ossification in every bird's sternum seems to have been accepted as a general truth, without contradiction, whereas in the ostrich and the rhea, at any rate, L'Herminier found that there were but two such primitive points, 3 and from analogy 1 Their value was, however, understood by Gloger, who in 1834, as will presently be seen, expressed his regret at not being able to use them.
