          least I will describe that part that I have examined. The cases are built
 against the wall from the floor to cieling [i.e. ceiling] which is low, they are divided
 into compartments w/ pigeonholes rather more than a foot high, not
 quite so wide and nearly twice that depth, so that the papers are
 slid into them endways. There are curtains (no glass) to each case which
 are hoisted or let down by a pully & rope concealed in a box at [crossed out: each end] one side
 and when hoisted roll up under the top of the case so as to be out of sight.
 Eash plant is put spearately into a paper to whic it is fastened by [?]
 pasted on, & each paper is loose. The names of the Classes Orders & Genera
 are on bits of different coloured cards which are pasted to half sheets which
 are also loose. They are then arranged [crossed out: and] properly & laid loosely in the
 compartments. When any plant is wanted [added with caret: or] if any one wishes to examine
 some herbarium, the whole bundle can be taken out and laid on a table, care
 being taken in looking though it to turn over each leaf like the leaf
 of a book, so that [added with caret: the] arrangement may not be disturbed. 


 The quantity of paper [added with caret: &] of room that this plant requires is the greatest
 objection to it, & the papers lying loose makes them more accessible to
 the attaks of insects. For regular arrangement & convenient reference
 however it seems the best I am acquainted with, & these you know
 are the great desiderata in an Herbarium.
