number was very great, and muft conti- 
pually increafe, as the influence of that 
peace not onlv prodpeed a new organiza- 
tion of the Germanic Empire in general, 
hut likewile important changes in the, 
ftates cither augmented or transferted in 
coniequence of the fyftem of muemnifiea— 
tion; aad itis even thought that a Con- 
cordat, fimilar to that iately~ concluded. 
betwixt Bonaparte and the Pope, will

the documents relative *o thele-changes, 
a new journal was begua on purpolr, en-.
