SOLTAU, in Geography, a town of Weftphalia, in the 

 ■principaUty of Luneburg Zelle. The inhabitants arc for 

 the moil part clothiers; 29 miles N.N.W. of Zell. N. 

 lat. 53°4'. E. long. 9^55'. 



SOLTCAMP, a town of Holland ; 13 miles N.W. of 

 Groningen. 



SOLTE, a river of Germany, which runs near Klop- 

 penburg in Munller, and joining the Vehne, takes the name 

 of Soeft, on the borders of Friefland. 



SOLTENHAGEN, a town of Hinder Pomernnia ; 

 8 miles E. of Zachan. 



SOLTKOTT, a town of Weftphalia, in the bifliopric 

 of Paderborn, famous for its fait- works ; 6 miles S.W. 

 of Paderborn. 



SOLTZ, a town of Germany, in the county of Heniie- 

 berg ; 4 miles N.W. of Meinungen. 



SOLVA, a river of South Wales, in the county of 

 Pembroke, northward of Milford Haven, which forms the 

 port and harbour of the little town of the fame name. 

 This froall town is fituated in a deep valley, pervaded by the 

 above-mentioned river. Molt of the houfes are of modern 

 ereftion, and exhibit a neat appearance. They lie princi- 

 pally on the weftern fide of the vale, forming one ftreet in 

 the direftion of the river, but fcattered without plan or 

 order on the ftcep acclivity above. Solva is a fea-port, and 

 carries on a fmall commercial intercourfe with the adjacent 

 parts of thecoalt, chiefly with Milford. Its rapid increafe 

 in Cze, of late years, is an evidence of its profperity. 



SOLVACH Bay, a creek of South Wales, on the N. 

 fide of St. Bride's bay ; 3 miles E. of St. David's. 



SOLUBILITY of Sails, in Chemiftry, denotes their ca- 

 pacity to unite with, and remain fulpended in water ; and 

 the different falts poflefs different degrees of folubility, re- 

 quiring more or lefs of this fluid for their folution. See Salts. 

 SOLUBLE, in Medicine, loofe, or apt to go to llool. 

 In chemiltry it fignifiea eafily dillolvable. 



Soluble Tar/ar. See Tartar, and Tarlrale of Pota/h, 

 under Salts. 



Soluble Matter of Plants, in Agriculture, the foluble 

 parts of them, or the portion of vegetable matter which 

 they contain, and which is capable of folution and of being 

 employed as the food and nourifhrnent of man and animals. 

 The quantities or proportions of this matter, which different 

 plants or vegetable fubftances poflels, is very different. It 

 is confequently not improbable, but that the difference in 

 the nutrient powers of different plants and fubllances of the 

 vegetable kind may, in a great meafure, depend upon this 

 difference in the quantities or relative proportions of the 

 foluble matter which they may contain, but their utility 

 and importance as food do not appear to be wholly de- 

 pendent upon this circumilance. 



S0LUIU.K Matter of Soils, the refolvable matter in them, 

 or the quantity and proportion of this fort of matter which 

 they contain in different cafes, and which is capable of be- 

 ing converted to ufe as food for the fupport and growth 

 of plants as crops. Some foils abound much with materials 

 of this nature, while others arc almoll wholly deficient of 

 them. This, in fome degree, coaftitutes the difference of 

 fertility in lands, though it is influenced by a great variety 

 of other caufe.'!. See Soil. 



The rich black foils are, for the moff part, the mod 

 ajjundantly provided with tJiis kind of matter, though many 

 others pollefs it in a confiderable proportion. 



SOLUE, in Geography, a town of Africa, in the coun* 

 try of B^rca ; 10 miles S.W. »f C«iou.

SOLVENT, the fame with dl/folvent. See Solltion. 



Solvent, Univerfal, in Alchemy. See Alkahest. 



SOLVESBORG, in Geography. See SoLtwiTZBruo. 



SOLUMBERE, a town of Hiudoollan, in the circar 

 of Oudipour; 35 miles S. of Afawully. 



SOLUMBERGA, a town of Italy, in Friuli ; 7 miles 

 N. of Aviano. 



SOLUS, in Ancient Geography, a town of Sicily, ac- 

 cording to Pliny ; marked in the Itinerary of Antonine as 

 the route from the Lilybjean promontory to the Tyndaris, 

 between Panormus and Thcrmx. — Alfo, a promontory 

 of Libya, on the coall of the Atlantic fea, according to 

 the Periplus of Scylax. A temple, dedicated to Vengeance 

 and Neptune, was erefttd on the fummit of this pro- 

 montory. 



SOLUSAPRA, a town of Sicily, on the route from 

 Tyndaris to the Lilybxan promontory, according to the 

 Itinerary of Antonine. 



SOLUTIO CoNTiNUi, or Solution of Continuity, a term 

 ufed by phyficians, &c. to exprels a diforder common to 

 the folid parts of the body, in which their natural cohelion 

 is feparated : as by a wound, or other caufe. 



If this happen to a fimple, fimilar part of the body, it 

 is called limply folutio continui : if to a compound or or- 

 ganical part, it acquires a particular denomination, from 

 the nature of the part, the difference of the caufe, or the 

 manner of application ; as a wound, rupture, fradure, punc- 

 ture, fijfure, contujion, ulcer, corrojion, dilaceration, exfoliation, 

 caries, &c. 



SOLUTION, SoLUTio, in Algebra and Geometry, if the 

 anfwering of a queftion ; or refolving any problem pro- 

 pofed. See Resolutio.v and Reduction of Equations. 



The folution of the problem of the quadrature of the 

 circle, and that of the duplicature of the cube, by right 

 lines, are held impoffible. 



Solution of Continuity, in Surgery. See Solutio Continui. 



Solution, in Phyftcs, the reduAion of a folid or firm 

 body into a fluid ftate, by means of fome menltruum. 



Solution is frequently confounded with what we other- 

 wife call dijfolution, but there is a difference. 



Solution, in Chemiftry, is fometimes ufed for the ana- 

 lyfis, or reduftion, of a natural body into its chemical prin- 

 ciples. 



In this fenfe, folution ii the fame with what we other- 

 wife call refolution. 



Solution, as the term is commonly ufed by chemicd wri- 

 ters, coiifills in an union formed by the integrant parts 

 of one body with thofe of another body of a diflercnt 

 nature; and this eannot be cffedlcd till the aggregati.m of 

 one, at lead, of the two bodies is broken. And as bodies, 

 whofe aggregation is broken, nre ncceffarily in a fhite of 

 fluidity, or of vapours, an axiom has been formed, corpora 

 non agunt niji Jintjuida, i. e. bodies do not aft unlefa they 

 be fluid. 



The two bodies which unite in folution, are commonly 

 diffinguilhed by two different names. That body is gene- 

 rally called the folvait, which, by its fluidity or acrimony, ap- 

 pears to be aftive ; and the body which, from its want of 

 tafte, or from its folidity, appears to be altogether paliive, 

 is faid to be dijfolved. E. g. When metal or marble is dif- 

 folved in aqua forti*, the folid bodies .ire confidcrcd as be- 

 ing diliolved, and aqua fortis as the folvent. Ncverthelefs, 

 it mud be remembered, that two bodies, which unite toge- 

 ther in folution, aft reciprocally upon om- another, and 

 their union is the effcft of their mutual affinity or tendency 

 to each other; and thus the marble and metal aft as much 

 upon the nitrpui acid as this does upon them.
