MfAKO'AH, or Mano'eh, [Heb. red.]- Father of 
.Sampfon; ot the tribe of Dan, and of the city of Zorah. 
Judges xiii. An angel of the Lord having appeared to 
the wife of Manoah, and having promifed her a fon j 
Manoah, whether moved by jealoufy, (fo fays Jofephus, 
Ant. lib. v. cap. ic.) or by gratitude, (fo fays Ambrofe, 
Ep. 70.) defired of the Lord that he might fee him who 
had thus appeared, that he might know? from him how to 
treat this fon who (hould be born; though that indeed 
had been already told ; (ver. 4, 5.) The Lord heard his 
prayer ; and the angel appeared again to his wife, being 
then in the fields; and fhe ran to acquaint her hufband. 
Manoah went to him, and obtained from him direiflions 
concerning the child. Manoah then faid, / pray thee, let 
us prepare a kid for thee. The angel replied, “ I mult not 
eat any food ; but thou mayelt offer it for a burnt of¬ 
fering to the Lord. - ’ Manoah faid to him, (not knowing 
him to be an angel,) What is thy name? that we may do 
thee honour when that Jhall happen which thou hajl foretold ? 
He anfwered, Why afkejl thou my name, feeing it is a fecret ? 
Manoah therefore took the kid, with the wine for the li¬ 
bation ; and put them on the fire which he had lighted 
.on a Hone, jofephus, w ho is followed by molt commen¬ 
tators, fays, that the angel touched the flelh with a rod 
in his hand, on which there iflued a flame that confumed 
the burnt facrifice; which circumltance is not mentioned 
in Scripture. As the fmoke began to afeend, the angel 
-alfo afeended in the midlt the flame towards Heaven. 
Then Manoah perceived that it was an angel ; and faid 
to his w ife, We fhall furely die, becaufe we have feen God. 
But his wife antwered, If the Lord were plcafed to kill us, 
he would not have received our burnt offering, nor would have 
prediElcd to us the birth of a fon. This happened A. M. 2848. 
an.d Sampfon was born in 2849, ante A.D. 1155.

Military manoeuvres confift chiefly in thofe various move¬ 
ments or evolutions, in which loldiers are exercifed, in 
.order to fit them for defenlive or offenfive operations. 
The platoon exercife has been altered as well as the ma¬ 
nual. The exercife is performed a little flower, three 
-Jeconds being allowed between each motion. It is no 
Jcnger done by fignai from beat of drum, but all by word 
of command. 
The infantry-manoeuvres, which were formerly fo nu¬ 
merous, are now reduced to 18 ; which are ordered to be 
!>ra6iifed and performed in every regiment. The follow¬ 
ing are the movements, explanations of which, and di- 
xebtions for performing them, are given in the books of 
-exercife. t. Forming the battalion into clofe columns in

MANOM'ETER, f. [from the Gr. y.ayoc, rare or thin, 
and jwcTpo!', meafure;] or Manoscope, [from pavot;, and 
c/.oirvj), to view.] An inftrument to fhovv or meafure the 
alterations in the rarity or denlity of the air. The ma¬ 
nometer differs from the barometer in this, That the latter 
only ferves to meafure the weight of the atmofphere, or of 
the column of air over it; but the former, the denfty of 
the arr in which it is found ; which denfity depends not 
only on the weight of the atmofphere, but alfo on the ac¬ 
tion of heat and cold, &c. Authors, however, generally 
confound the two together; and Mr. Boyle himielf gives 
us a manometer of his contrivance, under the name of a 
Statical Barometer, (fee vol. ii. p. 737.) but that in-; 
flrument, though it would evidently indicate the changes 
o i denfty of the atmofphere, llill leaves 11s uncertain as to 
the caufe, whether it is from a change of its weight, or of 
its temperature, or of both. 
The manometer conltrufted by Mr. Ramfden, and ufed 
by Capt. Phipps in his Voyage to the North Pole, was 
compoled of a tube of a fmall bore, with a ball at the end ; 
the barometer being at 29-7, a fmall quantity of quick- 
filver was put into the tube, to take off the communica¬ 
tion between the external air and that confined in the 
ball and the part of the tube below this quicklilver. A 
fcale is placed on the fide of the tube, which marks the 
degrees of dilatation arifing from the increafe of heat in 
this ftate of the weight of the air, and has the fame gra¬ 
duation as that of Fahrenheit’s thermometer, the point of 
freezing being marked 32. In this Hate, therefore, it will 
ihow the degrees of heat in the fame manner as a thermo¬ 
meter. But, if the air becomes lighter, the bubble in- 
doled in the ball, being lefs compreffed, will dilate itfeif, 
and take up a fpace as much larger as the comprefling 
force is lefs ; therefore the changes arifing from the in¬ 
creafe of heat will be proportionably larger; and the in- 
ltrument will Ihow the differences in the denlity of the air, 
arifing from the changes in its weigh* and heat. Mr. 
Ramlden found that a heat equal to that of boiling water, 
increafed the magnitude of the air from what it was at 
the freezing point of the whole. Hence it follows, 
that the ball and the part of the tube below the begin¬ 
ning of the fcale is of a magnitude equal to alrnolt 414 
degrees of the fcale. If the height of both the manome¬ 
ter and thermometer be given, the height of the barometer 
may be thence deduced by this rule; as the height of the 
manometer increafed by 414 is to the height of the ther¬ 
mometer increafed by 414, lb is 29-7 to the height of the 
barometer. 
Other kinds of manometers were made ufe of by Col. 
Roy, in his attempts to correct the errors of the barome¬ 
ter. “ They were (fays he) of various lengths, from four 
to upwards of eight feet 5 they conlilted ot Itraight tubes, 
whole bores were commonly from -j^th to -Jjth of an inch 
in diameter. The capacity of the tube was carefully mea- 
fured, by making a column of quicklilver, about threa or 
four inches in length, move along it from one end to the 
other. Thele (paces were leverally marked, with a fine- 
edged file, on the tub^s ; and transferred from them to 
long Hips of palfeboard, for the fublequent conttruclion of 
the Icaies relpedively belonging to each. The bulb, at¬ 
tached to one end of the manometer at the glals houfe, 
was of the form of a pear, whole point being occafionally 
opened, dry or inoilt air could be readily admitted, and 
the buib lealed again, without any lenlible alteration in 
its capacity. The air was confined by means ot a column 
of quicklilver, long or Ihort, and nith the bulb down¬ 
wards or upwards, according to the nature of the pro- 
poled experiment. Here it mult be oblerved, that, from 
the adlieiion of the quicklilver to the tube, the inltrument 
will
