oz. 
OZ. An abbreviation of ounce. The second let- 
ter here, while identical in form with the letter z, is really 
the character used by early printers for the arbitrary mark 
of terminal contraction, 3. which is common in medieval 
manuscripts. It occurs also in viz.

-ina'.] A subfamily of CaraUdce, typified by 
the genus Ozaina, having the middle coxse con- 
tiguous by reason of the extreme narrowness 
of the mesosternum. The species, usually 
found under fallen leaves, exhale a strong odor, 
whence the name. Also Ozcenidai.

ozocerite, ozokerite (6-zo-se'rit, -ke'rit), . [<

ture of natural paraffins existing in the bitu- 
minous sandstones of coal-measures. It is like 
resinous wax in consistence and translucency, of a brown 
or brownish-yellow color, and of a pleasantly aromatic 
odor. In Moldavia it occurs in sufficient quantities to be 
used for economic purposes, and it is made into caudles. 
A related resin is found in considerable quantities in 
southern Utah. Also called mineral tallow and mineral

ozocerite, ozokerite (6-zo-se'rit, -ke'rit), v. t. ;

ing, ozokeriting. [< ozocerite, n.] To treatwith 
ozocerite or native paraffin. Ozocerites core, an 
electrical conductor covered with india-rubber and after- 
ward " cured " or soaked in melted ozocerite under high 
pressure so as to fill the pores of the rubber with the par- 
affin wax. The name is also given to wires covered with a 
mixture of substances, as of asbestos and ozocerite. Ozo- 
cerited leads, heavy electrical conductors covered with 
any ozocerited compound.

OZOnation (6-zo-na'shon), n. [< ozone + -atioii.] 
The act or process of treating with ozone. 
Faraday. 
OZOne (6'zon), . [= F. ozone; < Gr. ieu; 
smell, + -one.'] A modification of oxygen, hav- 
ing increased chemical activity; a colorless 
gas having a peculiar odor like that of air 
which contains a trace of chlorin. The density 
of ozone is one and one half times that of oxygen. It is 
produced when the electric spark is passed through air 
or oxygen, when a stick of phosphorus is allowed to 
oxidize slowly, and in various other ways. At a high 
temperature ozone is changed into ordinary oxygen, two 
volumes of the former yielding three volumes of the 
latter. Chemical tests show that ozone exists in the at- 
mosphere to a minute extent, and in greater quantity in 
country districts than in towns, while in crowded thor- 
oughfares it ceases to be recognizable. Ozone has a great 
power of destroying offensive odors, and is a powerful 
bleacher and an intense oxidizer. 
The proportion of ozone in the air stands in a direct re- 
lation to the amount of atmospheric electricity present.

OZOne-box (6'zon-boks), n. A box in which 
ozonic test-papers are exposed to the free pas- 
sage of the air while protected from the light. 
Many different forms have been devised. 
ozone-paper (6'z6n-pa"per), n. A chemical 
test-paper used to indicate the presence and 
the relative amount of ozone in the air. See 
ozonoscope. 
ozonic (6-zo'nik), a. [< ozone + -ic.] Of or per- 
taining to ozone ; containing ozone. 
It I kauri gum] renders the air ozonic. 
Set. Amer., $. S., LV. 129. 
Having ozonic oxygen for its active principle, Condy's 
Fluid acts in harmony with nature. 
Lancet, No. 3441, p. 30 of adv'ts. 
Ozonic ether, a solution of hydrogen peroxid in ether: it 
has been used in diabetes, 
ozoniferous (6-zo-nif'e-rus), o. [< E. ozone + 
L. ferre = E. Scar 1 .] Containing ozone. Gra-

fied, ppr. ozonifying. [< ozone + -i-fy.] To 
produce or convert into ozone.

OZOnization (6-zo-ni-za'shon), n. [< ozonize + 
-titioii.] The operation of impregnating with 
ozone; the state of being impregnated with 
ozone. Also spelled ozonisiitioit, 
ozonize (6'zo-mz), v. t.; pret. and pp. ozonized, 
ppr. ozonizing. [< ozone + -ize.~] To impreg- 
nate with ozone. Graham, Elem. of Chemistry. 
Also spelled ozonixc. 
ozonizer (6'zo-ni-zer), H. An apparatus for the 
continuous production of ozone. Greer, Diet,

OZOnograph (6-zo'no-graf ), . [< E. ozone + Gr. 
)>pa<t>eiv, write.] Aii instrument for automati- 
cally exposing ozonic test-papers ; a self-acting 
ozonoscope. 
ozonographer (6-zo-nog'ra-fer), n. [As ozo- 
iiograph + -eel.] One skilled in observing at- 
mospheric ozone. 
OZOnometer (6-zo-nom'e-ter), n. [< E. ozone 
+ Gr. /ifrpov, measure.] A scale of tints with 
which ozonic test-papers are compared in order 
to determine the relative amount of ozone in 
the air. 
Ozonometers have been variously constructed and tried, 
but no clear and consistent results have yet been obtained 
by ordinary observers, so much individual tact is essential 
to dealing satisfactorily with the test papers and their al- 
terations. F itz Soy, Weather Book, p. 29. 
OZOnometric (6-zo-no-met'rik), a. [< ozonome- 
try + -ic.] Pertaining to the measurement of 
ozone. 
OZOnometry (6-zo-nom'et-ri), n. [< E. ozone + 
Gr. -fierpia, < uerpov, measure.] The art of mea- 
suring the relative amount of ozone in the at- 
mosphere. 
ozonoscope (o-zo'no-skop), n. [< E. ozone + Gr. 
GKOTreiv, view.] A test-paper which is oxidized 
and discolored by ozone. When properly exposed, 
the degree of discoloration indicates the relative amount 
of ozone in the air. Ozone-papers are usually either red 
litmus-paper dipped in a dilute solution of potassium 
iodide, or paper saturated with a mixture of potassium 
iodide and starch. In the litmus-paper the ozone decom- 
poses the potassium iodide and combines with the potas- 
sium, forming potash, by which the red litmus is rendered 
blue. In the iodized starch-papers, the ozone combines 
with the potassium, and the free iodine combines with 
the starch, forming a blue iodide of starch. 
ozonoscopic (6-zp-no-skop'ik), a. [< ozonoscope 
+ -ic.] Indicating the presence of ozone.
