of
the skin, the razor passing through the tips of the papillae, which
appear as tiny red points yielding a moderate ooze of blood.

The strips are obtained from the front and lateral aspects of the thigh
or upper arm, the skin in those regions being pliable and comparatively
free from hairs.

They are cut with a sharp hollow-ground razor or with Thiersch's
grafting knife, the blade of which is rinsed in alcohol and kept
moistened with warm saline solution. The cutting is made easier if the
skin is well stretched and kept flat and perfectly steady, the
operator's left hand exerting traction on the skin behind, the hands of
the assistant on the skin in front, one above and the other below the
seat of operation. To ensure uniform strips being cut, the razor is kept
parallel with the surface and used with a short, rapid, sawing movement,
so that, with a little practice, grafts six or eight inches long by one
or two inches broad can readily be cut. The patient is given a general
anaesthetic, or regional anaesthesia is obtained by injections of a
solution of one per cent. novocain into the line of the lateral and
middle cutaneous nerves; the disinfection of the skin is carried out on
the usual lines, any chemical agent being finally got rid of, however,
by means of alcohol followed by saline solution.

The strips of epidermis wrinkle up on the knife and are directly
transferred to the surface, for which they should be made to form a
complete carpet, slightly overlapping the edges of the area and of one
another; some blunt instrument is used to straighten out the strips,
which are then subjected to firm pressure with a pad of gauze to express
blood and air-bells and to ensure accurate contact, for this must be as
close as that between a postage stamp and the paper to which it is
affixed.

As a dressing for the grafted area and of that also from which the
grafts have been taken, gauze soaked in _liquid paraffin_--the patent
variety known as _ambrine_ is excellent--appears to be the best; the
gauze should be moistened every other day or so with fresh paraffin, so
that, at the end of a week, when the grafts should have united, the
gauze can be removed without risk of detaching them. _Dental wax_ is
another useful type of dressing; as is also _picric acid_ solution. Over
the gauze, there is applied a thick layer of cotton wool, and the whole
dressing is kept in place by a firmly applied bandage, and in the case
of the limbs
