The Etiology of Purulent Infection. —M. Flourens, 
in a note presented to the Academy of Sciences, gives an 
account of some experiments he has recently performed. He 
took some drops of pus from the dura mater of a dog and 
applied them to the perfectly healthy pleura of another dog. 
The dog died at the end of thirty-six hours, and a double 
purulent pleurisy was found to exist, the pleura being filled 
with pus, while no other viscus contained it. Pus was also 
applied to the abdominal muscles of a perfectly healthy dog. 
It died in four days, an enormous infiltration of pus having 
taken place amongst the different muscles of the abdomen. 
Moreover, pus transported from the dura mater to the pleura 
of the same animal caused death on the fifth day, the left 
pleural cavity being filled with pus. 
Vivisection. —It will be remembered by our readers that 
two years ago a deputation of the Royal Society for the Pre¬ 
vention of Cruelty to Animals, headed by Samuel Gurney, 
Esq., M.P., visited Paris and had an interview with the 
Emperor of the French, with a view* to the discontinuance of 
the horrible practice of cutting up animals alive in the French 
veterinary and anatomical schools. The Rev. Prebendary 
Jackson, of Stoke Newington, who formed one of the original 
deputation, has just been to Paris again in order to learn 
wdiat has been the result of the benevolent efforts of the 
society. It wdll be gratifying to the friends of humanity to 
know that whereas before the deputation went no limit or 
check was placed upon the practice of cutting up animals alive 
in France, but now all private and unauthorised vivisections 
are put a stop to by an ordinance of police. M. Magne, who 
has written strongly against the abuse of vivisection, has been 
appointed by the Imperial Government director of the college 
at Alfort, which is a pledge that the cruelties hitherto 
carried on there will cease; while at Lyons it has been 
determined that no incision shall be made in any animal till 
the organs of sensation have been thoroughly destroyed. 
These important results will no doubt greatly encourage the 
society in pursuing its efforts abroad in the interest of reli¬ 
gion, humanity, and civilisation.
