to inspect the precious estate u (Cannot read the name 
E.D.) and brousht the manusscripts here. On the basis of his fern 
collertion and the manuscript it is possible to compose an assembly 
and the characteristics of all knom ferns without too much trouble 
and I hope that somebody can be found to do this. The collection of 
ferns contains at least 3,500 species in 87 giant packages. 
I will be a to undertake the identification of the cha- 
raceae of Bolander, but I do not know what to suggest for the Liver- 
worts.Gottschle is a ver busy doctor in Altona,who does not have the 
time to study the material which he owms in abudand mass, nor to 
publish. However ‚it will take an inquiry if he will undertake at 
least an identification. It is well known, that he is the best con- 
nesseur of the liverworts,and, in fact, I know of nobody who has occupied 
himselfso thoroushly with the liverworts,but Mr. De Nolanez in 
Genoa and Vander Sande Lacoste in Amsterdam or Pain:

TI do not want to complete this letter bacause this could still take 
several days, but want to to close it today in a preliminary way, 
and then continue from day to day as time permits. Today I examined 
a small-leaved form of I. riparia from Uxbridee "sporifera reticu- 
lata "*. Everything matches riparia, even the macrospores are only 
a little different, the sporansium is well protected throush brown 
sclerenchymacells, which, however, are less crowded than with the 
normal riparia. But, of course, missing is so far the crosscut through 
Uyejeni! 
the leaf,an enterprise which takes time. On the basis of crosscuts 
of normal riparia and common Engelmanri,which were immersed some 
time in alkali-1ye, I decided today that genrally the main difference 
between the 2 species is this :that riparia has absolutely no peri- 
pherical vascular bundles, while Engelmanri has 4 rather strong
