  We study comparison of correlation functions for ferromagnetic generalized
Ising models with two different apriori measures. One purpose of this note is
to publicize some unpublished 45 year old work of Daniel Wells on the issue. We
then prove results for the apriori measures associated to one component of
D-vectors uniformly distributed on the unit sphere and also the case of spin S
(2S +1 equally spaced values symmetric about 0 and with equal weights) that
improves some 50 year old bounds of Griffiths on transition temperatures.
