INT 



to wit, tilt efforts of the hero for the execution of his de- 

 fign, and the efforts of thofe who thwart it. As thofe 

 caufes and defigns are the beginning of the adlion, fo thofe 

 .efforts are in the middle, and there form a knot or difSculty, 

 which we call an intrigue, that ir.akes the greateft part of 

 the poem. It lafts as long as the mind of the reader or 

 hearer is fufpended about the event of thofe oppofite efforts : 

 the folution or cataflrophe commences when the knot begins 

 to unravel, and the difficulties and doubts begin to clear 

 up. 



The intrigue or plot of the Iliad is two-fold ; the iird 

 comprehends the three days fighting in Achilles's abfence, 

 and confifts, on the one fide, in the refiftance of Agamemnon 

 and the Greeks, and on the other, in the inexorable temper 

 of Achilles. The deatli of Patroclus unravels this intrigue, 

 and makes the beginning of a fecond. Achilles refolves to 

 be revenged, but Heftor oppcfes his defign ; and this forms 

 the fecond intrigue, which is the laft day's battle. See 

 Iliad. 



In the , jEneid there are alfo two intrigues : the firft is 

 taken up in the voyage and landing of iEneas in Italy ; the 

 fecond in his eftablifhment there. The oppofition he met 

 •with from Juno, in both thofe undertakings, forms the in- 

 trigue. SeeiExEiD. 



As to the choice of the intrigue and the manner of unra- 

 velling it, it is certain they ought both to fpring naturally 

 from the ground and fubjeft of the pbem. Boffu gives us 

 three manners of forming the intrigue of a poem ; the firft 

 is that already mentioned ; the fecond is taken from the fable, 

 and defign of the poet ; in the third, the intrigue is fo laid, 

 as that the folution follows from it of courfe. 



Intrigue, in common language, is ufcd to denote a plot ; 

 a private tranfaftion in which feveral parties are engaged, 

 and ufually an affair of love. .Tohnfon.

INTRODUCTION, in Rhetoric, is the firft part of an 

 oration or difcourfe, defigned to prepare the minds of the 

 hearers for the fuitable reception of the fucceeding parts : 

 and for th.is purpofe it is neceffary that the orator gain the 

 . good opinion of his hearers, fecure their attention, and give 

 them fome general notion of his fubjeft. In order to gain 

 the good opinion of his hearers, the orator, when he intro- 

 duces the difcourfe with his own perfon, will be careful to 

 do it with modefty, and feem rather to extenuate his virtues 

 and abilities, than to magnify them : when he fets out with 

 the perfors of thofe to whom the difcourfe is addrefTed, it 

 is not uuufual to commend them for their x'irtues, and thofe 

 efpccially which have a more immediate relation to the pre- 

 fent fubjeft. The other topics which are to be infilled upon 

 for gaining efteem, are principally taken from the fubjecl, as 

 itsjuftice, importance, advantage, or pleafure. In fpeaking 

 of gaining the attention of the hearers, Cicero fays, we fhall 

 be heard attentively by one of thefe three things ; if we 

 propofe what is great, neceffary, or for the interelt of thofe 

 to whom the difcourfe is addrefTcd. Some account of the 

 fvibjeft fhould always make a part of the introduftion. As 

 to the compofition of this part of a difcourfe, it fhould ap- 

 pear eafy and natural, and connefted with the reft of the 

 difcourfe: it (hould be fuited toils length: the language of 

 it fhould be jnft, eafy, and pleafant : it ought neither to be 

 • wholly without pafiions, nor too violent and impetuous. It 

 ought not to be too general, the iatroduftion, however, is

INTRODUCTOR, in Antiquity, was particularly ufed 

 for an officer, who introduced the atUetiE to the ftadium, or 

 place where tliey were to contend. 



INTROITUS, in the Roman Ritual, as fettled by St. 

 Gregory, is an introduftion to high mafs on great feftivals, 

 preceding the ufual pfalms. 



INTROMISSION, m Natural Hipry, is a term relat- 

 ing to the petrifaftion of organic fubltances, in which mi- 

 neral fubflitution takes place, during the removal of the or- 

 ganic particles, (the mineral being giaduaUy introduced into 

 the animal or vegetable body,) fupplying the place, and 

 taking the form of the matter loft. By this mode of petri- 

 faftion the internal fabric, as well as the external figure of 

 the original is preferved. Petrified wood has ufually par- 

 taken of this kind of change. See W. Martin's Outlines, 

 p. jj. Petrifaftions formed by intromiffion, are fometimes 

 faid to he ingenerate. Outl. p. 67. 



INTRONATI, the name of an academy at Sienna, in 

 Italy. 



The members of this academy contented themfelves, at 

 their firft inftitution, with eftablifhing the following fix fhort 

 laws: I. To pray. 2. To ftudy. 3. To be merry. 4. To 

 offend nobody. 5. Not to credit too lightly. 6. To let the 

 world talk. 



INTRO SUSCEPTION, in Surgery. See Intussus-

INTRUSION, in the Canoti La-w, fignifies the enjoy- 

 ment of a benefice, or exercife of an office, without a good 

 title to it. 



The word is derived from intrudere, to thnijl in, or enter 

 byfnree. 



Iiitrufion difqualifies the partj from ever holding the be- 

 nefice. 



Intritsion, Information of, in Law, is a method of fuit, 

 by information on behalf of the crown, filed in the exche- 

 quer by the king's attorney-general, for any trefpafs com- 

 mitted on the lands of the crown, as by entering thereon 

 without title, holding over after a leafe is determined, taking 

 the profits, cutting down timber, or the like. See Ini-ou- 



MATION. 



Intrusion a'fo denotes the entry of a ftranger, after a 

 particular eftate of freehold is determined, before him in re- 

 mainder or n-verfion. This entry and interpofition of the 

 ftranger differ from an abatement in this; that an abatement 

 is always to the prejudice of the heir, or immediate devifee ; 

 an intrufion is always to the prejudice of him in remainder 

 or reverfion. An intrufion is always immediately cmfequent 

 upon the determination of a particular eftate; an abatement 

 is always confequent upon the defcent or devife of an eftate 

 in fee-fimi)le. And in either cafe the injury is equally great 

 to him whofe poffeffion is defeated by this urdawful occu- 

 pancy. See Ous-TEa. 



INTRUSIONE, a writ brought againft an intruder, by 

 him that hath fee-fimple, &c. See IVril of Entry. 



INTUI riON, among Logicians, the acl whereby the 

 mind perceives the agreement or difagreement of two ideas, 

 immediately by themfelves, without the intervention of any 

 other : in which cafe the mind perceives the truth, as the 

 eye doth the light, only by being dircfted toward it. Thus 

 the mind perceives that white is not black, that three are 

 more than two, and equal to one aivd two. See luE.v. 



This part of knowledge, fays Mr. Locke, is irrefiftible, 

 and, like the funfh'ne, forces itfelf immediately to be per- 

 ceived, as foon as the mind turns its view that way. It is 

 on this intuition that all the certainty and evidence of our 



other
