12 DICTIONARY OF BIRDS 
The British Museum had been formed, and he had access to everything 
it contained in addition to the abundant materials afforded him by the 
private Museum of Sir Ashton Lever! Latham entered, so far as the 
limits of his work would allow, into the history of the Birds he described, 
and this with evident zest, whereby he differed from his French pre- 
decessor ; but the number of cases in which he erred as to the determina- 
tion of his species must be very great, and not unfrequently the same 
species is described more than once. His Synopsis was finished in 1785 ; 
two supplements were added in 1787 and 1802,? and in 1790 he pro- 
duced a Latin abstract of the work under the title of Index Ornithologicus, 
wherein he assigned names on the Linnean method to all the species 
described. Not to recur again to his labours, it may be said here that 
between 1821 and 1828 he published at Winchester, in eleven volumes, 
an enlarged edition of his original work, entitling it A General History of 
Birds ; but his defects as a compiler, which had been manifest before, 
rather increased with age, and the consequences were not happy.® 
About the time that Buffon was bringing to an end his studies of 
Birds, Mauduyt undertook to write the Ornithologie of the Encyclopédie 
Méthodique—a comparatively easy task, considering the recent works of 
his fellow-countrymen on that subject, and finished in 1784. Here it 
requires no further comment, especially as a new edition was called for in 
1790, the ornithological portion of which was begun by Bonnaterre, who, 
however, had only finished 320 pages of it when he lost his life in the 
French Revolution ; and the work thus arrested was continued by Vieillot 
under the slightly changed title of Tableau encyclopédique et méthodique des 
trois regnes de la Nature—the Ornithologie forming volumes four to seven, 
and not completed till 1823. In the former edition Mauduyt had taken 
the subjects alphabetically ; but here they are disposed according to an 
arrangement, with some few modifications, furnished by D’Aubenton, 
which is extremely shallow and unworthy of consideration. 
Several other works bearing upon Ornithology in general, but of less 
importance than most of those just named, belong to this period. Among 
others may be mentioned the Genera of Birds by Thomas Pennant, first 
printed at Edinburgh in 1773 in octavo, and very rare, but well known 
by the quarto edition which appeared in London in 1781; the Hlementa 
Ornithologica* and Musewm Ornithologicum of Schiffer, published at Ratis- 
bon in 1774 and 1784 respectively ; Peter Brown’s New Illustrations of 
Zoology in London in 1776; Hermann’s Tabule Affinitatum Animalium 
at Strasburg in 1783, followed posthumously in 1804 by his Observationes 
1 In 1792 Shaw began the Musewm Leverianum in illustration of this collection, 
which was finally dispersed by sale in 1806, and what is known to remain of it found 
its way either to the collection of the then Lord Stanley (afterwards 13th Earl of 
Derby), and was, at his death in 1851, bequeathed to the Liverpool Museum, or to 
Vienna (Zbis, 1873, pp. 14-54, 105-124; 1874, p. 461). Of the specimens in the 
British Museum described by Latham not one exists. They were probably very im- 
perfectly prepared,
