ANNALES DE L’INSTITUT PASTEUR 
Attempts at conlirming Fornet’s cultural experiments hâve 
been unsuccessful. 
Gullural experiments with other media and methods bave 
also given négative results, although the virus lias not been 
killed bv incubation for 8 weeks at 33°C. 
Addendum. — Tbis paper was sent to tbe Pasteur Institute 
in April 1914. In June 1915, Noguchi [10] published suc- 
cessful intra-testicular inoculations of vaccinia in rabbits and 
bulls. I then again tried inoculations in tbe testes of guinea 
pigs, obtaining a positive resuit in but one out of five expe¬ 
riments. Using rabbits, however, I got results similar to those 
of Noguchi, thus confirming in vivo my cultures in vitro [11].
