Page 116 - Unless a species or jfroup is intelligibly defined when the name is given, it cannot be recognized by others, and the signification of the name is consequently lost Two things are necessary before a zoological term can acquire any authority, viz^ definition and publication. Definition properly implies a distinct exposition of essential characters, and in all cases we conceive this to be indispensable...
Page 111 - For these reasons, we have no hesitation in adopting as our fundamental maxim, the " law of priority," viz. § 1. The name originally given by the founder of a group or the describer of a species should be permanently retained, to the exclusion of all subsequent synonyms (with the exceptions about to be noticed) . Having laid down this principle, we must next inquire into the limitations which are found necessary in carrying it into practice.
Page 111 - Linnseus, it is clear that, as far as species are concerned, we ought not to attempt to carry back, the principle of priority beyond the date of the 12th edition of the
Page 437 - That the quantity of heat produced by the friction of bodies, whether solid or liquid, is always proportional to the quantity of force extended.
Page 116 - In Latinizing modern words the rules of classic usage do not apply, and all that we can do is to give to such terms as classical an appearance as we can, consistently with the preservation of their etymology. In the case of European words whose orthography is fixed, it is best to retain the original form, even though it may include letters and combinations unknown in Latin. Such words, for instance, as Woodwardi, Knighti, Bullocki, Eschscholtzi, would be quite unintelligible if they were Latinized...
Page 94 - Hallcy downwards, can be deemed either conclusive or satisfactory by any unbiassed mind, that shall give them a strict and impartial examination. The grand error into which the whole school of meteorologists appear to have fallen, consists in ascribing to heat and rarefaction the origin and support of the great atmospheric currents which are found to prevail over a great portion of the globe.
Page 115 - ... of the thing signified to the etymological meaning of the sign, and hence it is necessary to provide that the latter shall not be such as to propagate actual error. Instances of this kind are indeed very rare, and in some cases, such as that of Monodon...
Page 123 - F. It is recommended that in subdividing an old genus in future, the names given to the subdivisions should agree in gender with that of the original group. [Etymologies and types of new genera to be stated.'} It is obvious that the names of genera would in general be far more carefully constructed, and their definitions would be rendered more exact, if authors would adopt the following suggestion : — § G.
Page 122 - The authority for a species, exclusive of the genus, to be followed by a distinctive expression.] The systematic names of zoology being still far from that state of fixity which is the ultimate aim of the science, it is frequently necessary for correct indication to append to them the name of the person on whose authority they have been proposed. When the same person is authority both for the specific and generic name, the case is very simple ; but when the specific name of one author is annexed...
Page 117 - We are aware that a large number of other regulations, some of which are hereafter enumerated, have been proposed and acted upon by various authors who have undertaken the difficult task of legislating on this subject ; but as the enforcement of such rules would in many cases undermine the invaluable principle of priority, we do not feel justified in adopting them. At the same time we fully admit that the rules in question are, for the most part, founded on just criticism, and therefore, though we...
