I gotta ask, what the heck is "DMSO"?  Maybe I should know, but the shortage of sleep nowadays is keeping me from figuring this out. 

If it's a cure-all, for frozen ears, I know I need some.  We try and dry the ears as best we can when we first find a calf but sometimes the tips are already froze.  It'd be nice to smear something on and save the rest of the ear without spending too much time on any particular calf.
