Disquisitiones Arithmeticae Chapter 8? Does anyone know where I can find the posthumously published (I think) chapter 8 of Gauss's Disquisitiones Arithmaticae?
According to the German edition of Wikipedia you can find the eighth chapter in here.
I have read some information that it may have been published as 'General Investigations of Curved Surfaces' however I am having some difficulty confirming.
