paper money, and, indeed, by notes of clean, and, to the naked eye, 
unaltered surface. 
I have scraped off some of these minute incrustations with hol- 
lowed-out scalpels and needles and divided them into fragments in 
distilled v;ater that had been boiled shortly before, and, upon exam- 
ining them with lenses of high power (R. T. Beck's i-ioth inch), 
have seen the various Schizomycetes distinctly. 
I can now proceed to give a brief account of the results I have ob- 
tained from the investigation of the paper money. I have investigated 
the Hungarian bank and State-notes, recent and old (from the years 
1848-49), also Russian rubel notes, and have found bacteria upon all 
of them, even upon the cleanest. 
On the surface of all the paper money is always to be found the 
special bactgrium of putrefaction, viz.. Bacterium TermOy Dujardin. 
In the thin incrustations on the paper money I ascertained the oc- 
currence of starch-grains (especially those of wheat), linen and cot 
ton fibres and animal hairs, and, in this deposit upon the forint State- 
notes, the Blastomycete Saccharomyces cerevisice in full vegetation. 
Various Micrococci, Leptofriches (many with club-shaped, swollen 
ends) and Bacilli are also the most frequent plants in the deposit of 
the paper money. 
The two ntv^ species of algas described by Paul Reinsch are very 
rare on paper money. The ^x^^w Pleurococcus c€i\% have been ob- 
served in some cases on i- and 5-forint State-notes, and the bluish- 
green, minute Chroococcus on the border of the 5-forint State-notes. 
The vegetation of the paper money is, according to my researches, 
composed of the following minute- plants: 
(i.) Micrococcus (various forms); (2.) Bacterium Termo; (s-) 
Bacillus (various forms); (4.) Leptothrix (species?); (5.) Saccharo- 
myces cereviscBj (6.) Chroococcus monetariim; (7.) Pleurococcus niQne- 
tarunu From a hygienic point ot view, an investigation of the com- 
monest household objects, and especially of books, etc., used by 
students, may not be superfluous.

Recent Changes in Plant Nomenclature. — Dr. Gray, in his 
Manual, enumerates less than 400 monopetalous species from Capn- 
foliace^ to Compositas, inclusive. The just published Flora, Vol. J-? 
Pt. ii., makes one hundred changes in the nomenclature of these 
plants. For the benefit of the numerous students and teachers using 
his Manual (considering that about one fourth the species are to re- 
ceive diffelent names), the names of the species thus affected are giv-en 
below, together with the corresponding name in the Flora, ^j'*^^ 
has been thoroughly revised, and the limits of the species, as ^^'^^^ ^^ 
their nomenclature, have been changed so much that reference to 
Flora alone can adequately show in what the changes really consis^ 
SoUdago is revised as indicated in Studies of Aster and Solidago i 
the Older Herbaria. i^f^/« becomes Valerianella; Diplopappus, Aste, 
Cirsium, Cnicus; Nabalus, Prenanthes; Mulgedium, Lactuca. 
numerous other changes can be seen in the followmg list:
