ut taking into consideration the vastness of the subject,
I must refer them to text-books, such as Beale's "How to Work with the
Microscope;" Lankester's "Half-hours with the Microscope;" Hon. Mrs.
Ward's "The Microscope;" Davies "On the Preparation and Mounting of
Microscopic Objects;" G. E. Davis' "Practical Microscopy;" Gosse's
"Half-hours with the Microscope;" Wood's "Common Objects of the
Microscope;" any of Quekett's works, and to late numbers of the
Monthly Microscopical Journal, Nature, Science Gossip (the latter
teeming with practical hints on all matters connected with natural
history), and hosts of other works.
This chapter, dealing as it does with details and hints upon many
subjects, may fittingly be closed with scraps forgotten in the body of
this work, but which now occur to me as being useful knowledge.
STARCH AS PASTE: (see chapter IV).--Procure some common starch (that
which is white looking is perhaps the best), mix it up with a little
cold water, just sufficient to dissolve it, stirring it thoroughly to
prevent lumps. Pour upon this sufficient boiling water to make it into
a stiff paste. This will be found most useful for clean paper or
photographic work, as it enables paper to be pasted on cardboard, etc.
without creasing. The paper should be first wetted on the face side,
the back pasted with the starch-paste, fixed on the cardboard, and the
whole dried off by blotting paper. For common taxidermic work, paste
containing resin (sold at leather merchants') is strong and cheap.
BEST GLUE, made in the ordinary manner, but rather thicker than usual,
then poured into a bottle containing enough methylated spirit to thin
it, is recommended as being a strong medium to stick paper on wood or
cardboard, with the advantage claimed for it that it does not cause
the thin wood or cardboard to "cast" or "buckle."
MARINE GLUE dissolved in diluted acetic acid makes a strong cement for
certain things, such as mending shells. This, as also the preparation
of Formula No. 33, should be kept in bottles, or small stoppered jars,
and melted for use by surrounding with hot water.
LEATHER is (so says a bookbinder) to be pasted, after it is damped on
the outside. Cloth is to be glued. This is useful to know if making up
cloth-covered boxes with leather backs, to imitate books (see Chapter
XV, on Entomology).
ANTI-INSECT NOSTRUMS (see chapter IV).--Russian tallow in saucers, oil
of birch, flowers of sulphur, helleb
