in a line at the top by itself. Up to the end of the 32nd Heft 
in the 1st Edition, “ Jnhalt ” is printed with a long J, whereas 
it is short in the 2nd, and from the 28th Heft to the end of the 
37th in the 2nd Edition, the line under the heading is long, 
i. e., considerably longer than the “ Inhalt,” but in the Ist 
Edition it is quite short, and not nearly so long as the Inhalt 
From the end of the 37th Heft I can trace the 2nd Edition, or 
a re-issue of the 1st, up to the end of the 72nd Heft by the 
short line under “ Tah ” on the covers ; in the 1st Edition they 
are just about the length of “ Tab,” or a little longer, in the 2nd 
Edition, or reprint, they are clearly shorter. After Heft 72, 
which would be the last of the 6th Jahrgang, I can find no 
trace even of a re-issue. 
After Heft 37, as I mentioned above, both Editions are 
alike, as far as the numbering and names are concerned, but 
why no alterations occur after this date I have failed to find 
out. I think, however, it is probable that no changes were 
made after the publication of the “ Kritische Revision ” in 
1806, and it is not improbable that the 3rd “ Jahrgang ” of the 
2nd Edition would be completed about this time, or a little 
before it, as the 1st was dated 1796, the 2nd 1799. The curious 
point is that the alterations do not cease after the 36th Heft, 
which would be the end of the 3rd Jahrgang, but after the 
37th. The 37th and the 38th in the 1st Edition are given up 
to species bearing the authority of Kugelann to their names on 
the covers ; in the 2nd Edition, as one might expect, the 
authority is changed in the 37th Heft to that of other authors, 
as Eabricius, lUiger, &c.; but in the 38th Kugelann is retained 
throughout, and it is practically a reprint of the 1st Edition. 
After this point the only signs of a second issue with which 
I am acquainted are the slight differences in the style of 
printing the covers, sufiiciently decided to show that they 
could not have been struck off the same plate as those of the 
1st Edition, but of no importance at all otherwise. 
My object in the following pages has been to give a com-
