"Morphological" Quotes from Famous Books
 ... it is our clear conviction that, as the evidence stands, it is not absolutely proven that a group of animals having all the characters exhibited by species in nature, has ever been originated by selection, whether natural or artificial. Groups having the morphological character of species, distinct and permanent races, in fact, have been so produced over and over again; but there is no positive evidence at present that any group of animals has, by variation and selective breeding, given rise to another group which was in the least ...

... concerning Cretinism, or Human Deterioration, in its Various Forms and Degrees"), by Maffei and Roesch (two vols, Erlangen, 1844). But, in order that these data should be of value, the observed anomalies and defects of the cerebral functions ought to be capable of being referred to careful morphological investigations of the cretin brain. As the authors give no results of post-mortem examinations, I simply ...

... differentiated forms. It is simply a fact, that evolution of the individual animal and plant is taking place, as a natural process, in millions and millions of cases every day; it is a fact, that the species which have succeeded one another in the past, do, in many cases, present just those morphological relations, which they must possess, if they had proceeded, one from the other, by an analogous process ...

... the marvellously complex radiate and lattice-work skeletons of Radiolarians were regarded as a mere outflow of "Nature's infinite wealth of form," as an instance of a purely morphological character with no biological significance. But recent investigations have shown that these, too, have an adaptive significance (Haecker). The same thing has been shown by Schuett in regard to the lowly unicellular plants, the Peridineae, which abound alike on the surface of the ocean and ...

... in Rome tend to demonstrate that the schizomycete of malaria does not always assume the complete bacillary form described by Klebs and myself; but this morphological question possesses no further interest for the hygienist.
