Vnde patet faltem vsque ad 200 multitudinem nume- 

 rorum qui non funt fummie duorum quadratorum , ma- 

 iorem eflfe quam eorum qui funt fummae ,duorum qua- 

 dratorum. Ceterum infpicienti ftatim patebit neutram 

 iftornm numerorum feriem certa et aflignabili lege coff* 

 tineri ; atque ob hoc ipfum difficilius erit vtriusque in> 

 dolem inueftigare* 



§. 3. Cum omnis numerus quadratus (it vel par , 

 hocque 1 cafir per 4 diuifibilis et in hac forma 40 con- 

 tentus , vel impar , hocque cafu in hac fbrma %b-\-x 

 contineatur : omnis numerus ex duobus quadratis compo- 

 fitus erit vel i mo . fumma duorum quadratorum parium , 

 et ad hanc formam 4^-4-4^ pertinebit \ eritque ergo 

 per 4 diuifibilis. 



Vel 2 do . Summa duorum quadratorum alterius pa:— 



ris alterius imparis , et propterea in huiusmodii formsu
