In a paper published in these Proceedings I proved that there are only a finite number of quadratic fields in which Euclid's Algorithm (E.A.) holds. Recently Davenport has found a new proof of this theorem based on the theory of the minima of the product of linear inhomogeneous forms.

† We preserve the convention that small italics denote positive rational integers, but d need no longer be a prime, p continues to denote rational primes.
‡ We define α1 ≡ α2 (mod m), if two integers β1, β2 exist such that β1 ≡ β2 ≡ 1 (mod m) in the usual sense and α1β1 = α2β2. We call a number prime to d, if it is the quotient of two integers which are both prime to d.
