IO 
« lobiis florentinus and now I am assured both by Amici et Par- 
« latore that you must by this time have received it. What 
« Amici has seen is certainly highly curious and he has pro- 
« mised me some day under his wondrous microscope that 
« I shall see it as clearly as himself. 
« If it is truly a new genus and not an Oidium as Berkeley 
« supposed, still, if the same as your plant, it must be cal- 
« led Tuckeri and not florentinus. Amici has likewise pro- 
« mised to show me the pollinic sack placing it self by the 
« side of the nucelle contrary to the opinion of Schleiden, 
« which in fact always appeared to me inadmissible and which 
« I never could have behaved, unless like San Tommaso in- 
« credulo, I had touched it, and now I am to see the con- 
« trary. 
« The winter at Rome has been one of the wettest on re- 
« cord, several times the flavus Tiber started from his bed 
« surrounded the temple of Vesta and inundated the ripetta. 
« One evening on returning after dark I stepped into up to 
« my knees. 
« Madame la comtesse Fiorini is anxious to hear from you 
« an answer to her letter. She is still deeply engaged in 
« changing Nostoc is merely a form, an anamorphosis, as 
« she expresses it, of Collema. 
« In illustration of this opinion she is drawing the plant 
« from its first appearance as a Nostoc till it puts on the 
« garb of Collema or under more favourable conditions beco- 
« mes a true Collema. All this she vili have explained to 
« you better that I can, who have not studied these unin- 
« viting beings. 
« I signori commendatore Parlatore e cavaliere Amici de- 
« sired me yesterday to offer you their compliments and ser- 
« vices. 
« You well know that you command those of yours most 
« truly et aff. tely
