        Alright.  In the interest of keeping the theromdynamics and heat
transfer discussions on the list up to snuff (as I myself have personally
muddied the waters in the past), would someone please step in and answer the
following questions on this topic before we go on.:
        [Mickey, if you have time, please feel free to [] comment to your
hearts content (within the moderation rules, of course).]
        1: Does heat loss progress at a different rate than heat gain,
ceteris paribus?  If so, is it possible to guesstimate a ballpark figure of
the coefficient for a big sauropod?
        2: Is rate of heat loss dependant on outside temperature?
