To INTERPLE'AD, v. a. [from entre, Fr. between, and 
plaider, to plead ] To difcufs a point which incidentally 
turns up before the main caufe is determined. Scott. 
INTERPLEADER, / A procefs to difcufs or try a 
point incidentally happening as it were between, before 
the principal caufe can be determined. Interpleader is 
allowed, that the defendant may not be charged to two 
feverally, where no default is in him ; as, if one brings 
detinue agninft the defendant upon a bailment of goods, 
and another againft him upon a trover, there (hall be 
interpleader, to afeertain who hath right to his action, 
a Danv. Abr. 779. If two bring feveral detinues againft 
A. B. for the fame tiling, and the defendant acknow- 
ledges the action of one of them, without a prayer of in¬ 
terpleader, they fliall not interplead on the requeft of the 
other ; for the interpleader is given for the fecurity of 
the defendant, that he may not be twice charged, and he 
hath waived that benefit. 18 Edio. III. 22. There was 
formerly interpleader relating to delivery of lands by the 
king, to the right heir, where two perfons out of wardfliip 
■were found heirs, See. And anciently this head (fpelt En- 
terpleader) made a great title in the law. 
There are alfo bills of interpleader in a court of equity. 
Thus, where two or more perfons claim the fame thing by 
different or feparate interefts, and another perfon, not 
knowing to which of the claimants he ought of right to 
render a debt or duty, or to deliver property.in his cuf- 
tody, fears he may be hurt by fome of them, he may ex¬ 
hibit a bill of interpleader againft them. I11 this bill he 
muft ftate his own rights, and their feveral claims; and 
pray that they may interplead, fo that the court may ad¬ 
judge to whom the thing belongs, and he may be indem¬ 
nified. Mitford’s Treat. 47. The principles upon which 
courts of equity proceed in thefe cafes, are fimilar to thofe 
by which the courts of law are guided in-the cafe of bail¬ 
ment, the courts of law compelling interpleader between 
perfons claiming property, for the indemnity of a third 
perfon in whofe hands the property is, in thofe cafes only 
■where, by agreement of both claimants, the property has 
been bailed to a third perfon ; and the eburts of equity 
extending the remedy to all other cafes (leaving thofe o? 
bailment to the common law) to which in conlcience it 
ought to extend. Idem, 125. If a bill of interpleader does 
not fhow that each of the defendants, whom it feeks to 
compel to interplead, claims a right, both the defendants 
may demur; one, becaufe the bill (hows no claim of right 
in him; the other, becaufe (for that very reafon) the bill 
fhows no caufe of interpleader. 1 Vez. 248. Or, if the bill 
fhows no right to compel the defendants to interplead, 
whatever rights they may claim, each defendant may de¬ 
mur. As the court will not permit fuch a bill to be 
brought in collufion with either claimant, the plaintiff 
muft annex to his bill an affidavit that it is not exhibited 
in collufion with any of the parties ; the want of which 
affidavit is a caufe of demurrer. 1 Vez. 248. A bill of 
this nature generally prays an injunction to reftrain the 
proceedings of the claimants in fome other court; and, 
as this may be ufed to delay the payment of money by 
the plaintiff, if any is due from him, he ought by his bill 
to offer to pay the money due into court. Mitf. 126. Af¬ 
ter a decree on a bill of interpleader, there is generally an 
end of the fuit as to the plaintiff; and, if he dies, the

INTERPLICA'TION, / [from inter, Lat. between,- 
and plico, to fold ] The ait of folding up between; that 
which is folded up between. Phillips. 
To INTER'POLATE, v. a. [interpokr, Fr. interpolo, 
Lat.] To foift any thing into a place to which it does not 
belong.—The Athenians' were put in polfeffion of Salamis 
by another law, which was cited by Solon, or, as fome 
think, interpolated by him for that purpofe. Pope. —To re¬ 
new ; to begin again ; to carry on with intermiffions. In. 
this fevfe it is not in ufe. —This motion of the heavenly bo¬ 
dies themfelves feetns to be partly continued and unin- 
termittecC as that motion of the firft moveable, partly in¬ 
terpolated and interrupted. Hale .— That individual hs,th 
neceflarily a concomitant fucceflion of interpolated mo¬ 
tions ; namely, the pulfes of the heart, and the fucceffive 
motions of refpiration. Hale. 
INTER'POLATING, / The a ft of foifting in; the 
aft of renewing. 
INTERPOLATION, /. Something added or put into 
the original matter.—I have changed the fituation of fome 
of the Latin veries, and made fome interpolations. Cromwell 
to Pope. 
Interpolation, in modern algebra, is ufed for find¬ 
ing an intermediate term of a feries, its place in the feries 
being given. The method of interpolation was firft in¬ 
vented by Mr. Briggs, and applied by him to the calcu¬ 
lation of logarithms, Sec. in his Arithmetics Logariih- 
mica, and his Trigonometria Britannica ; where he ex¬ 
plains, and fully applies, the method of interpolation by 
differences. His principles were followed by RegiqaTand 
Mouton in France, and by Cotes and others in England. 
Wallis made ufe of the method of interpolation in va¬ 
rious parts of his works; as his Arithmetic of Infinities, 
and his Algebra, for quadratures, Sec. The fame was 
alfo happily applied by Newton in various ways ; by it 
lie inveftigated his binomial theorem, and quadratures of 
the circle, ellipfe, and hyperbola. Newton alfo, in his 
Principia, gave a moft elegant folution of the problem for 
drawing a curve line through the extremities of any num¬ 
ber of given ordinates ; and,, applied the folution of this 
problem to that of rinding, from certain obferved places of 
a comet, its place at any intermediate time. And Dr. 
Waring, who adds, that a folution (till more elegant, on 
fome accounts, has been fince difeovered bv Meffrs. Ni- 
chol and Stirling, has alfo refolved the fame problem, and 
rendered it more general, without having recourfe to find¬ 
ing the fucceffive differences. See Phil. Tranf. vol. lxix. 
part 1, art. 7. 
When the ift, 2d, or other fucceffive differences of the 
terms of a feries become at laft equal, the interpolation of 
any term of fuch a feries may be found by Newton’s Dif¬ 
ferential Method. See the article Fluxions, vol. vii. 
When the algebraic equation of a feries is given, the 
term required, whether it be a primary or intermediate 
one, may be found by the’ refolution of affefted equa¬ 
tions; but, when that equation is not given, as it often 
happens, the value of the term fought muft be exhibited 
by a converging feries, or by the quadrature of curves. 
See the article Algebra, vol. i. p. 309-315.
