ecliptic, every thing elfe, which hath been inferred 
from the phenomena of the {pots, feems altogether 
to be matter of conjecture, hevelius-, from his great 
fondnefs of the fubjedt, and from a defire to avail 
himfelf of that long courfe of obfervation, to which 
he had fo patiently fubmitted, has been led into 
many {peculations concerning the fpots and the 
nature of the fun’s body. The following quotations 
furnifh us with a remarkable inftance of this, and 
will ferve to give us a view of the ideas, which he 
came to entertain upon thefe fubje&s. In his Co- 
metographia, p 3^0, {peaking of the folar fpots he 
exprefles himfelf thus : 
44 Haec materia nunc ea ipfa ell evaporatio et ex- 
u halatio (quia aliunde minime oriri poteft) quae ex 
44 ipfo corpore folis, ut fupra oftenfum eft, expiratur 
44 et exhalatur: quae penitus ex diverlis partibus 
44 heterogeneis, certos gradus opacitatis et denlitatis 
44 habentibus, conftat, modo ex tenuioribus, modo 
44 opacioribus, modo ficcioribus, modo magis vif- 
44 cofis, glutinofis (ut noftro loquar more ufitato) 
44 five bituminofis. Unde etiam diverfa procreantur 
44 phrenomena 4 ex tenuioribus, purioribus, etficciori- 
44 bus, umbrae videlicet faculaeet luculae ; ex impuri- 
44 oribus vero eraflloribufque illis vifcofis, maculae 
44 eorundemque nuclei progignuntur. Cum ergo 
44 folis exhalationes ejufmodi partes fint hetero- 
44 geneae, quidni etiam illud ipfum corpus, quod eas 
44 ejaculatur, prout in pmecedentibus fufe aftertum 
44 eft, ex diverfis partibus heterogeneis conftabit r 
44 Ad haec, quia tales admirabiles et manifeftiffimae 
44 generationes, mutationes, alterationes, condenfa- 
tiones, rarefaCtiones* coitiones, diduCtiones, imo
