J. Prodrome dune nouvelle Distribution systématique du Régne 
Animal, Par H. de Blainville. 
In the last number of our Annals, we promised to lay before our 
readers some account of the system of the classification of animals 
proposed by that learned and indefatigable zootomist Professor 
Blainville ; but as it is our intention to compare it with the systems 
of Professors Cuvier and De Lamarck, and to make some general 
observations on each, we must state the ideas of the former natu- 
ralist as briefly as possible. 
His first notions on the subject were given in his public lectures 
in 1810; since which time he has devoted himself to the examina- 
tion of the internal structure of organized beings, on which his 
classification and general distribution is founded. But what parti- 
cularly demands our admiration is, that he has found external cha- 
racters by which to distinguish each group. His next object is, to 
endeavour to establish a rational nomenclature, that will at the same 
time point out the most striking characters and situation of each 
group in his system; but he has carried this no furtber at present 
than to designate the primary divisions. We shall make remarks as 
we proceed, but shall first give a tabular view of his general classi- 
fication, or distribution into—1, Sub-kingdoms. 2. Types. 3, Sub-
