MAMMALIA. 25 



into eighteen orders and forty-two genera. In 1777, about a 

 year before the death of Linnams, Erxleben published a work en- 

 titled Sy sterna Regni Animalis. The merit of his work is high, 

 both in regard to the discrimination of the species and the sy- 

 nonymous terms. He increased the Linnaean number of genera 

 by ten. 



Next followed Gmelin's edition of the Systema Natures in 

 1788. This work contained all the new objects in Natural His- 

 tory which had been described since the publication of the twelfth 

 edition; but the compilation was made without sufficient ex- 

 ercise of critical judgment, and the work is in consequence not 

 of much authority. 



Gottlieb Conrad Christian Storr, professor, published in 

 1780 at Tubingen a thesis, under the title of Prodromus Me- 

 thodi Animallum, remarkable for its distinct arrangement. 

 The leading characters are taken from the form of the feet. 

 Boddaert, a physcian in 1785, and Vicq-d'Azyr in 1792, each 

 proposed arrangements for the classification of animals; but 

 as these have not been generally adopted, it is not necessary to 

 enter into the details. 



Professor Blumenbach of Gottingen published a Manual of 

 Natural History in 1807, in which he attempted to form a more 

 natural system for the Mammalia, which he divides into nine or- 

 ders, viz. 



I. Bimana, VI. Bisulca, 



II. Quadrumana, VII. Multungula> 



III. Chiroptera, VIII. Palmata, 



IV. Digitata, A. Glires,

M. Cuvier, in 1798, published his Tableau Elementaire des 

 Animauaf. This sketch contained the basis of classification which 

 he afterwards developed in his Anatomic Comparee and Regne 

 Animal. Two years afterwards appeared the first two volumes of 

 the Comparative Anatomy ; to which were added synoptic tables 

 of all the classes of animals. In 1804, M. Desmarest published* 

 in the 24th volume of the New Dictionary of Natural History, a
