15 Oriolus In the latter arrangements of birds, although it cannot be said that the authors have lost sight of their great predecessor Linnaeus, yet the necessity of deviating from him must seem obvious, when the very great number of species which have come to our knowledge of late years, sufficient to justify such alteration, and satisfy the most scrupulous advocates of this great man, is considered. In his last edition of the *Systema Naturae*, Linnaeus enumerates about 930 birds only; but in the Index and Synopsis of Mr Latham, they have been increased to very near 4000, a number never imagined by former writers on the subject to exist in nature.

M. Biber, in his excellent treatise Oeconomia Nature aman. acad. vol. 2. calculates the probability of the vegetable kingdom furnishing as far as 10,000 species; that of the vermes 2000; insects 10,000; amphibia 300; fishes 2000; birds 2000; quadrupeds 200.

How far we have already exceeded this number in every department the naturalist can testify; but how much farther the list may be increased, no one will pretend to foretell, whilst the ardour and indefatigable industry of the present race of naturalists, added to the taste for possessing new acquisitions, and exploring new countries, shall continue.
