THE ROYAL HERBARIUM AT MUNICH. _ 105 
of Bavaria ; and it will furnish periodical reports of the results of all 
these combined researches. _ 
Such, then, are the principal elements of the treasure of dried plants, 
which the Royal Herbarium has acquired since its foundation to the 
year 1850, consisting, at present, on computation, of 42,000 species. 
Its arrangement is that of Endlicher’s ‘ Genera Plantarum’ (Vindobonæ, 
1836-40, 2 vols. 8vo). It is placed partly in high presses with glazed 
doors ; partly in low cabinets. Each specimen is fixed by means of glued 
strips of paper on half a sheet of royal folio paper, having the labels of 
the authors or contributors attached. The autographs are carefully 
preserved, in order to enhance the historical value of the collection. 
Specimens belonging to the same species are all put within a common | 
sheet of greyish paper, havingpin a similar manner, the specific name 
attached at the lower end on the left side. All the species of one 
genus are similarly placed in a wrapper of blue paper, bearing the sys- 
tematic generic name; and the genera are kept in portfolios, closed by 
means of tape. As a security against insects, a great number of papers 
drenched with styraa liquida are scattered among the packets; and the 
specimens which are known to be especially subject to attacks from in- 
sects, are powdered with mercurius dulcis, at the time when they are 
first attached to the paper, or subsequently from time to time. For 
security's sake, part of the collection is annually examined during 
summer. 
With regard to the catalogue, the arrangement is likewise that of 
Endlicher, according to the natural families and genera; but the species - 
are in alphabetical order. Up to the present period, the general cata- 
logue is finished as far as Leguminose, inclusive. 
The index of species in Zuccarini’s herbarium was so far advanced, 
that he was able to finish the acotyledons and monocotyledons. _ 
There is a similar index of the specimens belonging to the Royal | 
Ludwig-Maximilian University ; they have already been incorporated, — 
from time to time, with the general herbarium. A regular entry is 
separately made of each accession to the herbarium. It is the inten-  - 
tion of the conservator to furnish the sheets of the general herbarium 
with a current number, as soon as the business of gluing the specimens 
to papers of uniform size shall have been accomplished ; which, being — - 
added to the catalogue of species, will serve as a check on the general - 
number of specimens.
