A = (i, i) J- ergo (1,1)=^ 



;A=r(i,2)^^ ergo (i,0 = ^ 



iA -(1,3)3^ ergo (1,3) = *^ 



^Az=:(i,4)^^ ergo (1,4) =11 



■,A = (i,5)^ ergo (i, 5) =: ^ 

 ^A=r:(i,^)-£ ergo (i,6)=-JL 

 ;Ar=(i,7)^-L ergo (1,7) = ^^ 

 ^Aziz(i,8)^ ergo (i,8)=:l^ 



(i,9)(io, i)=:(i, 0(2,9) 

 (i,9)(io, 2)r(i,2)(3, 9; 



(1,9) (10, 3) = (1,3) (4, 9/ 

 (1,9) (10,4) = (1,4) (5, 9, 



(i,9)(io, 5) = (i, S)(6,9j 

 (i,9)(io, 5) = (i,(J)(7, 9) 



(^9)(io, 7) = (i,7)(8,9) 

 (i,9)(io, 8) = (i,8)(9,9. 



hocque modo feptem nouas dcterminationes fumus adepti.
