Still it seems advisable to furnish some connected account of the progress made in the ornithological knowledge of the British Islands and those parts of the European continent which lie nearest to them or are most commonly sought by travellers, the Dominion of Canada and the United States of America, South Africa, India, together with Australia and New Zealand.
Coming now to works on British birds only, the first of the present century that requires remark is Montagu's Ornithological Dictionary (2 vols.
In the following year Vigors returned to the subject in some papers published in the recently established Zoological Journal, and found an energetic condisciple and coadjutor in Swainson, who, for more than a dozen years - to the end, in fact, of his career as an ornithological writer was instant in season and out of season in pressing on all his readers the views he had, through Vigors, adopted from Macleay, though not without some modification of detail if not of principle.
In 1781 Nash's Worcestershire included a few ornithological notices; and Walcott in 1789 published an illustrated Synopsis of British Birds, coloured copies of which are rare.
Gray, first in the Appendix to Dieffenbach's Travels in New Zealand (2843) and then in the ornithological portion of the Zoology of the Voyage of H.M.S.
GREENSHANK, one of the largest of the birds commonly known as sandpipers, the Tetanus glottis of most ornithological writers.
Though a comparatively small number of species of birds are figured in this magnificent work (seventeen only in the first series, and twenty-two in the second), it must be mentioned here, for their likenesses are so admirably executed as to place it in regard to ornithological portraiture at the head of all others.
But, confining ourselves to what is here our special business, it is to be remarked that perhaps the heaviest blow dealt at these strange doctrines was that delivered by Rennie, who, in an edition of Montagu's Ornithological Dictionary (pp. xxxiii.-1v.), published in 1831 and again issued in 1833, attacked the Quinary System, and especially its application to ornithology by Vigors and Swainson, in a way that might perhaps have demolished it, had not the author mingled with his undoubtedly sound reason much that is foreign to any question with which a naturalist, as such, ought to deal - though that herein he was only following the example of one of his opponents, who had constantly treated the subject in like manner, is to be allowed.
To Dr Cabanis we are indebted for the ornithological results of Richard Schomburgh's researches given in the third volume (pp. 662-765) of the latter's Reisen im Britisch-Guiana (8vo, 1848), and then in Leotaud's Oiseaux de file de la Trinidad (8vo, 1866).
Peculiarities of the skeleton or portions of the skeleton of certain birds - one of the most remarkable of which is that on the component parts of the foot (pp. tot - toy) pointing out the aberration from the ordinary structure exhibited by the Goatsucker (Caprimulgus) and the Swift (Cypselus) - an aberration which, if rightly understood, would have conveyed a warning to those ornithological systematists who put their trust in birds' toes for characters on which to.
