able thereon from testator's death ; but if 

 charged only on the personal estate, 

 which cannot be immediately got in, it 

 shall carry interest only from the end of 

 the year after the death of the testator. 

 Where lands are charged with payment 

 of a sum in gross, they are also chargeable 

 in equity with payment of interest for 

 such sum. 



INTERJECTION, in grammar, an in- 

 declinable part of speech, signifying some 

 passion or emotion of the mind. As the 

 greatest part of the expressions used on 

 these occasions are taken from nature 

 alone, the real interjections, in most lan- 

 guages, are monosyllables ; and as all na- 

 tions agree in these natural passions, so 

 do they agree in the signs and indications 

 of them, as of love, mirth, &c. See GUAM- 

 MAR. 



INTERLOCUTOR? judgments, in law, 

 are such as are given in the middle of a 

 cause, upon some plea, proceeding, or 

 default, which is only intermediate, and 

 : does not finally determine or complete 

 the suit. 



INTERLUDE, an entertainment ex- 

 hibited on the theatre between the acts 

 of a play, to amuse the spectators while 

 the actors take breath and shift their 

 dress, or to give time for changing the 

 scenes and decorations. 



INTERMEDIATES, in chemistry, a 

 term made use of when speaking of che- 

 mical affinity. Oil, for example, has no af- 

 finity to water, unless it be previously 

 combined with an alkali, it then becomes 

 soap, and the alkali is said to be the inter- 

 medium which causes the union. 



INTERNAL, in general, signifies what- 

 ever is within a thing. 



Euclid (lib. i. prop. 32) proves, tkat 

 the sum of the three angles of every tri- 

 angle is equal to two right angles; 

 whence he deduces several useful corol- 

 laries. He likewise deduces from the 

 same proposition, this theorem, viz. that 

 the sum of the angles of every rectilinear 

 figure is equal to twice as many right an- 

 gles as the figure hath sides, excepting or 

 subtracting four. 



INTERPOLATION, among critics, de- 

 notes a spurious passage, inserted into 

 the writings of some ancient author. 

 One great rule with regard to the ex- 

 punging interpolations is, that the resti- 

 tution be perfectly agreeable to the rest 

 of the work. 



INTERPOLATION, in algebra, is used for 

 finding an intermediate term of a series, 

 its place in the series being given. 



INTERROGATION, or point of INTER- 

 VOL. VI. 



ROGATION, in grammar, a character of this 

 form (?) serving to denote a question. 



INTERROGATION, in rhetoric, is a figure, 

 whereby the orator proposes something 

 by way of question ; which, it must be 

 owned, greatly enlivens the discourse. 



INTERSECTION, in the mathematics, 

 signifies the cutting of one line or plane 

 by another. Thus, we say, that the mutu- 

 al intersection of two planes is a right 

 line. The centre of a circle, or conic 

 section, &c. is the intersection of two 

 diameters ; and the central point of a 

 quadrangle is the intersection of two di- 

 agonals. 



INTERVAL, in music, the difference 

 between two sounds, in respect of acute 

 and grave ; or that imaginary space termi- 

 nated by two sounds, differing in acute- 

 ness or gravity. 



When two or more sounds are com- 

 pared in this relation, they are either 

 equal or unequal in the degree of time j 

 such as are equal are called unisons, with 

 regard to each other, as having one tune ; 

 the other, being at a distance from each 

 other, constitute what we call an interval 

 in music ; which is properly the distance 

 in time between two sounds. Intervals 

 are distinguished into simple and com- 

 pound. A simple interval is without 

 parts or divisions. Such are the octave, 

 and all that are within it ; as the second, 

 third, fourth, fifth, sixth, and seventh, 

 with their varieties. A compound inter- 

 val consists of several lesser intervals; 

 such are all those greater than the octave, 

 as the ninth, tenth, eleventh, twelfth, &c. 

 with their varieties. 



INTESTINA, in natural history, the 

 first of the five orders of the class Ver- 

 mes, in the Linnxan system. This order 

 is described as of a formation the most 

 simple, being naked animals without 

 limbs. They live, some of them within 

 other animals, some in waters, and a few 

 in the earth. They are distinguished 

 from the Mollusca, by the want of move- 

 able appendages, or tentacula. There 

 are two divisions. 



A, found within other animals, without 

 eyes, of which there are fifteen genera*
