to ^ liBozic add,'' — a sticky sabstanoe, like toFDeBtme. By seve*
ml months farther exposure, the linozic acid aries and becomea



'^linoxyn," CQ2Ha70,|, — an amorphous, tough, leadiery matter
insoluble in water, alcohol, ether, or dilute acicb, but dissolving in
alkalis to reproduoe linoxates. Its best proper solvent is a mix-*
tore of alcohol and chloroform. Linoleate of lead readily oxydizea
in the air to a white linoxate, which is not glutinous, but dry, hard^
and brittle. And linseed oil boiled with a verv little oxyd of lead
so as to contain a small quantity of linoleate of lead, dries as well
in a few days as isolated linoieic acid does in so many months.
There are two linoxyns, the white and the red, and there are cor-
responding white and red Unoxic acids. The white modifications
be<M>me r^l by being heated to 80° C, and the red turn white
again by contmued exposure to sunlight The browning of white
paint in dark places, is owing to the gradual change of white lin-
oxyn into red. Four linoxic acids are mentioned, having the same
woperties, but differii ^i n respect to color and to the amount of
HO in combination. White Imoxic acid formed by the oxydation
of linoleate of lead, is HO,G3aH2 ^O^ ; thatproduced bv the ox-
ydation of free linoieic acid in the air, is n^O^C^^^ty^'^^^^*
\ Ked linoxic add when separated from red linoxate of lead by

chiorhydrio acid and dried at 100"" C, is 0,2^2 aO^. The second
, of the above white linoxic adds on being heated for some time in

j a water bath, loses 6*7 per cent and leaves a blood red linoxic acid

^ of Uie composition HOyCggHssO^. It will be noticed that lin-

^ oxyn, whicn is an indifferent substance, has a composition interm^

diate between this latter red linoxic add and the white from
^ which it is fonned; but of course in linoxyn the molecular arrange-

1 ment is different. Linoldo anhydrid^—C,2H2 702,— completes

^ the list of peculiar substances which exist or may be formed in

I drying oils. More or less of it is always formed during the boil-

ing of such oils, and it adds much to the goodness of boiled oiL
It is an unalterable, dastic matter, like caoutchouc that has been
^. melted.

I I^^PP7 B^^ ^^ <^d ^^t oil differ fit>m linseed oil in containing

laurin mstead of palmitin, and their linolein gives only the white
f variety liaoxyn. Hence not bein^ liable to turn brown m the dark,

^ they are better for artists' use. Lmseed oil consists of about 80 p. a

^ of unoldn, 10 p. c. of elaln, and 10 p. c. of mvristin and palmitm.

^ Mulder calls attention to what may be caUed the respiration of

r drying oils, for when they are spread out over a sreat smface they

^ absorb oxygen and give out carbonic add^ like the blood of living

^ animals. In drying, linseed oil increases m wdght to the amount

^ of from seven to twelve per cent over and above what it loses in

^ the form of water and carbonic acid, together with small portions

^ of acetic, formic, and acrylic acids. In the first place the glycerin

^ of the linolein is all decomposed and carried oiL Then the gly-

^ cerin of the other constituents is grradnall^ destroyed, so that at

iJl the end of three months not a trace of it is to be found. When

f this stage of the drying is completed, there remain linoxyn and

^ palmitic, myristic, and elaic ados, and the paint is dry and flexible

and elastic. ^ But oxy dation still goes on, though very slowly, and
the &tty acids disappear. Finally the linozyn itself undergoes de-
cay and becomes unserviceable in binding colors or in protecting
thepainted surface.

The albuminous or mucilaginous matter which has so long fig-
ured in the books to account for slowness in the drying of unboiled
oil, Mulder has searched for careiuUy but in vain ; and he finds
that fresh oil treated by any method which should simply remove
albumen or mucilage, still dries no better than before. And, after
all, this inappreciable substance, if it were present, would fail to
explain what it was indented to account ror: since Uiere is no
known reason why a matter that helps some oils oxydise to become
rancid, should hinder others from oxydizine to become dry. It is
therefore high time for science to consign this nonentity to the limbo
of obsolete follies.

The oxyds and acetates of lead act as driers, not by precipitating
albuminous matters, but by forming a little lineolate of lead, which
oxydizes readily and communicates its activity to the oil itself
The addition of some manganese salts, such as the borate, accel-
erates the drying, because the loosely held oxyd of manganese ox-
ydizes in the air and awakens the activity of the surrounding oil
l^o metallic oxyds or salts can act as driers unless they are brought
into a state to combine chemicallv with the oiL Thus red oxyd of
iron and zinc white and oxyd oi tin are entirely inert. Sulphate
of zinc or sulphate of manganese may act when oxyd of lead is
added to combme with the sulphuric acid and set the other oxyd
free ; but without such addition, they are useless ; and the oxyd of
lead reouired for the decomposition would do more good if used
alone. But oil treated with any driers by mere digestion, though
it may dry quickly, can never be so good as oil boikd with suitable
additions ; because in boiling some linoleic anhydrid is formed,
which beins more adhesive and elastic than linoxyn, adds much to
the value of oil for paint. The author, discarding numerous non-
sensical receipts which are extant, recommends for preparing a col-
orless drying oil, which leaves nothing to be desired, to boil com-
mon linseed oil two hours with three per cent of red lead, filter it,
and expose it to sunlight in large shallow vessels, the air over it
being frequently renewed.

Mulder returning at length to the problem which gave rise to
the investigation, rejects oil paints as unsuitable to prevent the
rusting of iron, and concludes that coal tar contains the best ma-
terials for a protecting coat.

The book contains a great deal that is new, and the author has
been, to use his own expression, *' Getren dem Grundsatze, welcher
uns Niederlandean von Jugend auf beigebracht wird, nicht so ohne
Weiteres dahin zu schreiben und sicher bei Behandlung von Oegen-
standen die Geschichte nicht zu vergessen." Of course he does not
entirely exhaust his subject, but science is greatly enriched by this
work, and it constitutes a masterly contribution to the chemistry of
the arts. ^ j. ic. o.
