IV 



Part II. of the present work, containing chapters on Iniagin- 

 aries, the Rational Integral Function of x, Solution of Numerical 

 Equations of Higher Degree, Graphic Representation of Equa- 

 tions, and Determinants, has already appeared and for this part, 

 as well as for the present volume, suggestions are invited. 



Several modifications have already suggested themselves to the 

 authors, but it is hoped that any into whose hands either volume 

 may fall will communicate with the authors with reference to any 

 changes before the work is put in permanent form.
