The eagle-stone was another lusus naturae as to its supposed virtue and origin, being only found in the nests of eagles which could not breed without their aid.

In a quadratic field Q (√), D a squarefree integer, with class number 1 any algebraic integer can be decomposed uniquely into primes but for only 21 domains Euclidean algorithms are known. We prove that for D<-19 even remainder sequences with possibly nondecreasing norms cannot determine the GCD of arbitrary inputs.
