BLOOD CORPUSCLES IN THE MAMMALIA. 



"We hope soon to publish an account of Mr. Gulliver's observa- 

 tions (in which he has been long engaged) on the blood disks of the 

 mammalia. In the meantime we may mention that in five Austra- 

 lasian animals the corpuscles have the form and size most common 

 in mammals, their diameters varying from :j:jy\yoth to s^jjth of an 

 inch. These Australasian animals are the Perameles lagotis, Petau- 

 riis Sciurus, Macropns Bennettii, Dnsyvms Ursinus, and D. Viverrinus. 



In reference to the interesting discovery by M. Mandl of the oval 

 blood cori:)UScles of the Dromedary, Mr. Gulliver has found the blood- 

 disks of the Auchenia Vicugna, A. Paco, and A. Glama, also very di- 

 stinctly elliptical. In the Vicugna they are rather smaller than in 

 the other species. 



In the Musk Deer (Tragahs Javanicus) Mr. Gulliver observes 

 that the blood disks are smaller than those, hitherto described, of 

 any other mammal whatever. In the Tragalus, the disks, though very 

 distinct in form, measure on an average y^ odo^^^ ^^ ^^^ ^'^'^^^ only ; 

 but many variations in size are to be seen, from yj^oH ^^ ^° u (J^o^^ 

 of an inch in diameter.
