Bohemian bole. See dote-'. Bohemian Brethren, 
the popular name of a religious denomination which de- 
veloped from the followers of Peter Chelczicky in the fif- 
teenth century. It reached its greatest influence in the 
sixteenth century, and was suppressed by Ferdinand II. in 
the seventeenth century in Bohemia and Moravia, but 
lingered in Poland and Hungary. It was revived in the 
eighteenth century as the Moravian Church. The mem- 
bers of the denomination called themselves the Unity 
of Brethren (Unitas Fratrum). Bohemian glass. See 
glagi. Bohemian pheasant. See pheasant. Bohe- 
mian waxwlng, Bohemian chatterer, a bird, the 
Ampelitt fjarrulu*, so called from the extent and irregu-

Boidae (bo'i- 
de), n. pi. 
[NL., < Boa 
+ -idee.'] A 
family of non- 
venomous ophidian reptiles, with two mobile 
hooks or spurs, the rudiments of hind legs, near 
the anus. The name has been adopted with varying 
limits, and latterly generally restricted to American spe- 
cies: (1) Colubrine snakes with the belly covered with 
narrow, elongate shields or scales, nearly resembling 
those of the back, and with spur-like rudimentary legs on 
each side of the vent. It included the Soidte as well as 
Pythonidce, Charinidce, and Tortricidw of recent ophi- 
ologists. (2) Eurystomatous serpents with rudiments of 
posterior extremities. It included the Boidre, Pythonida>, 
and Charinidae. (3) Eurystomatous serpents with rudi- 
mentary posterior appendages, coronoid bone in lower 
jaw, no supraorbital, but postorbital, bones in cranium, 
and with teeth developed in the premaxillary. In this 
limited sense there are still many species peculiar to the 
warmer regions of America, and among them are some of 
gigantic size, such as the boa-constrictor and anaconda, 
Eunectes munnuA They sometimes attack animals of a 
large size and kill them by constriction round the body.

bubble up or be in a state of ebullition, espe- 
cially through the action of heat, the bubbles 
of gaseous vapor which have been formed in 
the lower portion rising to the surface and es- 
caping: said of a liquid, and sometimes of the 
containing vessel : as, the water boils ; the pot 
boils. The same action is induced by diminished pres- 
sure, as when water boils under the exhausted receiver 
of an air-pump, or when carbon dioxid liquefied under 
high pressure boils upon the removal of the pressure. See 
Mling-point and ebullition. 
2. To be in an agitated state like that of boil- 
ing, through any other cause than heat or dimin- 
ished pressure ; exhibit a swirling or swelling 
motion ; seethe : as, the waves boil. 
He maketh the deep to boil. Job xli. 31. 
3. To be agitated by vehement or angry feel- 
ing; be hot or excited: as, my blood boils at 
this injustice. 
Then boiled my breast with flame and burning wrath. 
Surrey, ^Eneid, ii. 
The plain truth is that Hastings had committed some 
great crimes, and that the thought of those crimes made 
the blood of Burke Ml in his veins. 
ifacaulay, Wan-en Hastings. 
4. To undergo or be subjected to the action of 
water or other liquid when at the point of 
ebullition: as, the meat is now boiling. To boil 
away, to evaporate in boiling. To boil over, to run 
over the top of a vessel, as liquor when thrown into vio- 
612 
lent agitation by heat or other cause of effervescence ; 
hence, figuratively, to be unable, on account of excite- 
ment, indignation, or the like, to refrain from speaking ; 
to break out into the language of strong feeling, especial- 
ly of indignation. To boil up, to rise or be increased in 
volume by ebullition : as, paste is ready for use aa soon as 
it has once boiled up ; let it bail up two or three times. 
II. tram. 1 . To put into a state of ebullition ; 
cause to be agitated or to bubble by the ap- 
plication of heat. Hence 2. To collect, form, 
or separate by the application of heat, as sugar, 
salt, etc. 3. To subject to the action of heat 
in a liquid raised to its point of ebullition, so 
as to produce some specific effect; cook or 
seethe in a boiling liquid: as, to boil meat, 
potatoes, etc. ; to boil silk, thread, etc TO boil 
clear, in soap-manuf., to remove the excess of water from 
soft soap by boiling it. A concentrated lye is employed 
to shorten the time of evaporation. To boil down, to 
reduce in bulk by boiling ; hence, to reduce to smaller 
compass by removal of what can best be spared ; con- 
dense by elimination. 
After a while he [Bowles] developed a talent for con- 
densing into brief and readable form the long and heavy 
articles in which the great political papers of the day dis- 
charged their thunder. On these he began to practice 
that great art of boiling down which his paper afterward 
carried to such perfection. O. S. Merriam, S. Bowles, I. 23. 
To boil dry, in sugar-manuf., to reduce the thin juice 
to thick juice by boiling it until it reaches the point of 
crystallization.

ing: as, the boiling seas. (6) Heated; inflamed; 
bursting with passion : as, boiliiifi indignation. 
Boiling spring, a spring or fountain which gives out 
water at tile boiling-point or at a high temperature. The 
boist 
most remarkable tolling springs are the geysers, which 
throw up columns of water and steam ; but there art- 
many others in various parts of the world, often associ- 
ated with geysers, characterized only by ebullition and 
emission of steam. Some of the latter, as in California 
and >"ew Zealand, are strongly Impregnated with mineral 
matters and variously colored, while others are charged 
with liquid mud. See geyaer. 
boilingly (boi'ling-li), adv. In a boiling man- 
ner. 
The lakes of bitumen 
Rise boilingly higher. Byron, Manfred, i. 1. 
boiling-point (boi'ling-point), it. The tempera- 
ture at which a liquid is converted into vapor 
with ebullition ; more strictly, the tempera- 
ture at which the tension of the vapor is equal 
to the pressure of the atmosphere. Tins point 
varies for different liquids, and for the same liquid at dif- 
ferent pressures, being higher when the pressure is in- 
creased, and lower when it is diminished. Under the 
normal atmospheric pressure (see atmosphere) water boils 
at 212 F. (100 0., 80 B.), and it is found that the boiling- 
point varies .88 of a degree F. for a variation in the ba- 
rometer of half an inch. Hence water will boil at a lower 
temperature at the top of a mountain than at the bottom, 
owing to diminution in the pressure ; a fact which leads 
to a method of measuring the height of a mountain by 
observing the temperature at which water boils at the 
bottom of the mountain and at the top. At the top of 
Mont Blanc water boils at 185 F. Under a pressure of 
about -j-^ of an atmosphere water would boil at 40 F., 
while under a pressure of 10 atmospheres the boiling-point 
would be raised to 356 F. A liquid may be heated much 
above its true boiling-point without boiling ; but the 
superheated- vapor immediately expands until its temper- 
ature is reduced to the boiling-point. Hence, in deter- 
minations of the boiling-point, the thermometer is never 
immersed in the liquid, but in the vapor just above it. 
Kopp's law of boiling-points, the proposition that in 
certain homologous series of chemical substances each ad- 
dition of CH 2 is accompanied by a rise in the boiling- 
point of about 19.5 C.

from its capacity before the introduction of the metric 
system ; but in small trade the name is used for the de- 
caliter (one tenth of a hectoliter). In other parts of France 
the boisseau in old reckoning was generally much less
