Man and the Quadrumana, but larger than in the Ruminantia ; and 

 the same assertion has been extended to the Marsupiata, especially 

 that the red particles of the Perameles, which derives its nourish- 

 ment from the greatest number of organized substances, are larger 

 than the particles either of the carnivorous Dasyure or of the herbi- 

 vorous Kangaroo. 



" This opinion is not supported by numerous measurements given 

 by me in the ' Philosophical Magazine' for January, Februarj-, March 

 and August, 1840. In one of the Ruminants indeed the corpuscles 

 are singularly minute, but in another granivorous animal they are as 

 singularly large ; and they are larger in several of the Ruminants 

 than in some of the Curuivoru. Amop.g the marsupial animals, al- 

 though the corpuscles of the Perameles slightly exceed those of the 

 A'^iverrine Dasyure in size, yet in the Ursine Dasyure the corpuscles 

 are larger than in either, and just as large too as those of Bennett's 

 Kangaroo." 



An abstract of the measurements of the blood- corpuscles of the 

 order Ferx is subjoined. 



Measurements of the Blood-corpuscles of the order Fertc. 



The measurements are all expressed in fractions of an English 

 inch, and, for the sake of brevity, the average-sized corpuscles only 

 are mentioned, as deduced from numerous observations in each spe- 

 cies.
