Mr. Ralph Tate’s ‘Flora of the Shetland Isles Mr. Acland believes 
that it was gathered in the latter islands, and that Euphrasia Odontites, 
L., of which there were specimens, was also collected there; this is 
not included in Mr. Tate's paper. As E. obscurum has not been re- 
corded from either group, it seems worth making a note of.

MEMORANDA. 
DRIED Frowrns.—We have been favoured by Mrs. Scrivenor, of Alvingham 
dried Heliotropes, Forget-me-nots, and other Boraginee, in which the colour 
is preserved with difficulty, as we do not find any of these plants amongst the 
group. As the process by which Mrs. Scrivenor has achieved her object may 
interest some of our readers, we subjoin a detailed description of it :—“ A great 
mistake usually made by those who attempt drying flowers is to look upon 
weight and pressure as an essential part of the process. This is the chief cause 
of failure. To keep the colour in a flower, we should not take all the pains we 
to squeeze out the juices in which that colour resides. All our efforts, 
then, must be given to retain the colour by drying up the juices, and no more 
pressure must be used than will be required to keep the flower flat. The flowers 
fade, the drying will fail to prese: ee their colour. 
Do not hold them when cut in your hands, but throw them as they are ga- 
thered into a large handkerchief m so that they may not press one upon 
another. If the flowers are at all bruised or broken, it would be best to dis- 
eard them at once, as the juice would escape through the injured part. When 
you have gathered your flowers, take them from their foliage, leaving the stalk 
to ae flower from one to two inches long ; light a candle, and hold the flower- 
ne by one in the flame, until about a quarter of an inch i is quite burnt ; 
Pyret 
fleshy No; such as the Dielytria,—require to have their stalks dipped from 
ten to twenty minutes in a weak solution of water and muriate of lime in crys- 
tals before burning; while very fleshy green leaves should have their stalks 
first put in a solution of saltpetre and water. Provide yourself with some 
blotting-pads. The size sold for 4d. or 6d. per quire will be found most con-
