I don't have any numbers at hand here (time to go to bed, because I'll be taking exams tomorrow (not sitting myself, but asking questions to about 25 LCs to be) and the day after, so no time in the upcoming days either).
  Fat is lighter than water and some of the dry components of milk be heavier than water. So the exact composition of any given sample of milk may have a slightly other weight per volume (don't kow the English scientific word for the phenomenom that each material has it's own weight per volume compared to water as 1:1 = gram:mililiter), therefor sugar-rich lowfat milk will probably have a higher weight per mililiter then will high fat milk and the calorie count will be different as well (fat offering twice the calories of both proteins and sugars), as will be the amounts of carbohydrates and protein. So 10ml of milk from the breast can mean anything in terms of nutrients and calories.

Can you give me more information about this? Perhaps this is something that 
everyone knows except me.... Or point me to where I can find out about the 
weight of fat heavy milk vs low fat milk? I'm assuming the same would hold 
true for cow's milk -- so that a pint of heavy whipping cream would weigh less 
than a pint of skim milk. I don't have any on hand so can't weigh it out, 
but would love to know how much the differences would be.

I don't recall that Paula Meier made that sort of a differentiation in her 
study that showed that 1 ml of human milk weighed 1 gm but perhaps I missed it.
