EXC 



KXC 



n the thickness of the glass, though 

 some kinds of glass are more excitable 

 than others, and some not at all so. If a 

 coated electric jar be taken of about one- 

 twentieth of an inch in thickness, (see 

 JfeiB, electric,) a cylinder or plate mode- 

 rately excited, will require fifty or sixty 

 square feet to pass the cushion, in order 

 to charge one foot of the coated glass, so 

 as to explode over a rim of three inches, 

 which is as much as can be admitted with- 

 out danger of the explosion breaking 

 through the jar. If the excitation be 

 stronger, the charge may be made by 

 the friction of thirty feet to one of the 

 jar ; and the strongest excitation the edi- 

 tor has ever known has been by the fric- 

 tion of fourteen square feet of a cylinder 

 to charge one foot of glass. But as 

 the labour increases by adhesion of the 

 cushion, the stronger the excitation, it 

 seems as if the strength of a man would 

 be more profitably employed in turning 

 two or more plates, or cylinders, at the 

 intensity of thirty feet, than at any higher 

 intensity : besides which, this power is 

 less variable, and may last five or six 

 hours without requiring fresh amal- 

 gam. 



The vulgar notion of electricity is, that 

 it is fire which passes in a spark from one 

 body to another. From its passage through 

 dense conductors, as well as through the 

 air, it seems to move with extreme ve- 

 locity : and this may be sufficient, with- 

 out supposing it to be essentially lumi- 

 nous, to account for the ignited appear- 

 ance it affords, in all non-conductors, whe- 

 ther air, or oil, or glass, or wood, &,c. and 

 even in metal, when the conductor is 

 small. If oxygen be present, these bo- 

 dies will have their combustible parts 

 burned ; and if not, a decomposition 

 of those parts which are ignited may 

 ensue. 



EXCLAMATION, in rhetoric, a figure 

 that expresses the violent and sudden 

 breaking out and vehemence of any pas- 

 sion. Such is that in the second book 

 of Milton's " Paradise Lost :" 



"O unexpected stroke, worse than of 



death! 

 Must I thus leave thee, Paradise ? Thus 



leave 

 Thee, native soil ; these happy walks 



and shades, 

 Fit haunt of gods!" 



Other figures are the language of some 

 particular passion, but this expresses 



them all. It is the voice of nature, when 

 she is in concern and transport. 



EXCLUSION, or Bill of Exclusion, a 

 bill proposed about the close of the reign 

 of King Charles II. for excluding the 

 Duke of York, the king's brother, from 

 the throne, on account of his being a 

 papist. 



EXCLUSION, in mathematics, is a me- 

 thod of coming at the solution of numeri- 

 cal problems, by previously throwing out 

 of our consideration such numbers as are 

 of no use in solving the question. 



EXCLUSIVE is sometimes used adjec- 

 tively, thus: " A patent carries with it an 

 exclusive privilege ;" and sometimes ad- 

 verbially, as, " He sent him all the num- 

 bers from N 145 to N 247 exclusive ;" 

 that is, all between these two numbers, 

 which themselves were excepted. 



EXCLUSIVE propositions, in logic, are 

 those where the predicate so agrees with 

 its subject, as to exclude every other. 

 Thus, " Virtue alone constitutes nobility," 

 is an exclusive proposition. 



EXCOECARIA, in botany, a genus of 

 the Dioecia Triandria class and order. 

 Natural order of Tricoccse. Euphorbiae, 

 Jussieu. Essential character : ament na- 

 ked ; calyx and corolla, none ; styles 

 three ; capsule, tricoccous. There are 

 two species ; viz. E. agallocha and E. 

 Cochin Chinensis. 



EXCOMMUNICATION, in law, is of 

 two kinds, the less and the greater, 

 which last is the highest ecclesiastical 

 censure which can be pronounced; for 

 thereby the party is excluded from the 

 body of the church, and disabled from 

 bringing any action in the common law 

 courts ; he is also disabled to serve on 

 juries, or to be a witness in any cause ; 

 he cannot be attorney or procurator for 

 another ; he is to be turned out of the 

 church by the church wardens, and not 

 to be allowed Christian burial. He may 

 also, in some cases, be imprisoned until 

 he submits to the ecclesiastical jurisdic- 

 tion, as in case of refusing to answer to 

 a suit for tithes. 



EXCORIATION, in medicine and sur- 

 gery, the galling or rubbing off" of the 

 cuticle. To remedy this, the parts af- 

 fected may be washed often with warm 

 water, and sprinkled with drying pow- 

 ders, as chalk, hartshorn, but especi- 

 ally tutty, lapis calaminaris, and ceruse, 

 which may be tied loosely in a rag, and the 

 powder shook out on the disordered places.
