    er than that by which they form any fecondary combination, and fo on progreflively. xi5. In many inftafices, oxygenizement is fo ftrongly oppofed by the affinity of aggregation, that it does hot take place unlefs affifted by a degree of heat fufficient to melt or vaporize the oxy- genizable bafe. 116. It is alfo often accompanied by the extrication of caloric and light in a very confpicuous degree. To thefe the term com- bullion ffiould be confined \ and only fuch oxygenizable bafes as are capable of exhibiting thefe phenomena are combuftible. Thefe phenomena depend upon the new compound, having a weaker af- finity or lefs capacity than its conftituents for -light and caloric, which are therefore extricated. 117. If the combuftible body be vaporized, flame is produced, and the procefs is then denominated Inflammation. 118. By its union with oxygenizable fubftances, oxygen un- dergoes very various changes of its properties. In many inftan- ces, the compounds of oxygen are fluid or folid, opaque, coloured* incapable gf fupporting inflammation, and deleterious to animal or vegetable life. The changes which the oxygenizable bafes undergo, are no lefs confpicuous. Their form, colour, tafte, odour, denfity, permeability to light and ele&ricity, fpecific ca* loric, and, finally, their affinities, are often totally altered. 119. When, in confequence of oxygenizement, any fubftance acquires a four tafte,, and the properties of converting vegetable blues to red, and of faturating or deftroying the chara&eriftic pro- perties of alkalies and earths, it is faid to be acidified, and fuch compounds are termed Acids. 1 ao. When it does not acquire thefe properties, the compounds are termed Oxides. t2i. Many oxides are capable of being converted into acids, by combination with an additional quantity of oxygen. 122. Oxygenizable fubftances, combined with each other, are capable of combining as Ample fubftances with oxygen * and the oxides or acids which refult from fuch combinations, are termed Oxides or Acids with a double or triple bafe. 123. In general, the bafes which are leaffi Ample, unite with oxygen in the greateft variety of proportions. Primary Compounds of Oxygen, A. Binary, a a. with nitrogen ; 1. Atmofpheric air, 2.
