598 BARNHART: DATES OF THE NovA GENERA 
There is little doubt that the first two fascicles were dated 
“1815,” and that fascicle 10 was dated “‘1818”’; and it is not 
certain that these fascicles were not actually issued before the 
close of those years. In fact, all of the dates under which notices 
appeared in the “ Bibliographie de la France” may be as much as 
six or eight weeks later than the actual publication of the fascicles.
