ABSORPTION of viruses. 
1st. By the development upon the parts inoculated, and under¬ 
neath the eschars resulting from cauterization, of veritable pus¬ 
tules, whose sheep-pox nature was recognised, not by their charac¬ 
ter and progress only, but likewise, and especially, by the property 
possessed by the matter they furnished of reproducing like pus¬ 
tules in sheep inoculated from them. 
2dly. By the complete failure of re-inoculation of every one of 
the twenty-two animals, notwithstanding in such re-inoculations 
fresh matter was used whose activity had been tested by simulta¬ 
neous and completely successful inoculation of other animals. 
Whence it follows, 
So far as concerns the virus of acute glanders , that its absorption 
may take place in less than an hour ; and in so far as concerns 
sheep-pox virus, that it may happen in less than Jive minutes , 
whenever one or other of these poisons has been brought into 
contact with any point of the absorbent surface of the skin

Some Anatomical Considerations on the Ethmoid and 
Vomer, and Cartilaginous Septum of the Nose. 
By M. COLIN, Chef de Service at the Alfort School. 
Up to the present day, anatomists, leaning too much in their 
descriptions to the organization of man, have considered the 
ethmoid and vomer as distinct bones, and the former as isolated 
from the inferior part of the sphenoid. This, however, is not the 
case. 
Authors of comparative anatomy, who for a long time have 
recognised in most animals an anterior and posterior sphenoid bone, 
have remarked that these osseous pieces remain separate for a 
great part of life, and at length unite with the neighbouring bones 
rather than form an union with each other. This is now become 
an established fact. But what has hitherto been described as the 
anterior sphenoid bone is, in reality, nothing more than the princi¬ 
pal part or body of the ethmoid. 
Also the vomer , which has been looked upon as a separate bone, 
is, in reality, but an appendage of the ethmoid; its union with the 
convolutions of the latter being observable in several species of 
animals, even in the course ol uterine existence, a long time 
prior to birth. 
Indeed, the development of these bony pieces form an extremely 
interesting study, especially as it is very variable according to the 
species.
