we institute a comparison with reference to the loss from the 
inoculated disease, and that arising from natural infection, we find 
that it results quite in favor of the former; further we find the 
losses gradually diminishing with the perfection of the knowledge 
and method of inoculation. 
In 1853, Dr. Ludersdoiff was authorized by the £ ‘ Konig press, 
Laude Oeconomie-Collegiums,” to gather trustworthy information 
with reference to the value of inoculation, and reported : 
“ So far as his observations would allow of an opinion, the 
evidence gathered stood more in favor of, than against inocula¬ 
tion, and that the much-feared danger of this prophylacticum, 
bore no relation to the losses which resulted from natural infec¬ 
tion, and hence that inoculation was deserving of the most careful 
experiment.” 
At the request of the French Agricultural Minister, a com¬ 
mission was formed, and the result published, by Bouley in the 
Recueil de Med. Vetr ., 1854, page 161, from which we take the 
following : From 9163 animals inoculated in Belgium, of which 
accurate knowledge was obtained, no visible local reaction followed 
the inoculation by 1567, while same was evident by 7623 ; of 
these 682 lost their tails, 22 suffered from extensive gangrenous 
disturbances, and 237 died. Of 2181 animals inoculated in France, 
over which trustworthy information was obtained, 523 demon¬ 
strated no local reaction, while the same was apparent by 1658 ; 
of these 524 lost their tails, 10 suffered from extensive gangrene, 
and 57 died. 
Of 8643 well authenticated cases of inoculation in Holland, 
2119 gave negative results, while positive were obtained by 
'6024 ; of these 239 lost their tails, 2 suffered from extensive gan¬ 
grene, and 73 died. 
Of 2861 inoculated in Germany, England, Austria and Italy, 
about which authentic information was obtained, the Commission 
report that negative results came to pass by 1294, and positive by 
1567 animals; of these 147 lost their tails, 19 suffered from 
extensive gangrene, and 101 died. 
Belgium by about 16%, France 25%, Holland 25%, and in 
other lands 48%.
