Hi Roger,
(B
(BThank you for that information.
(B
(BActually I have briefly looked through Hills
(Btreatise (while standing up) but at the time I was
(Bsomewhat skeptical due partly to the long and flowery
(Btitle given to it and if I recall, it also seemed to lack
(Ba lot meat, so to speak. That said, I was and still am,
(Binterested in interference color synthesis and might have
(Ba copy of it with me... I will have to check my library...
(BIn anycase I guess I WILL have to look at it again.
(B
(BThanks again for the tip.
(B
(BI will see what the smithsonian has.
