But an excellent lesson for those of us coming up to speed on scientific instrumentation and measurement. Seems the scales need to be tared from time to time. I suppose it would have been obvious that there was artifact had the temperature been systematically lower the second time around. I think of an error that is in one's favor as a "banker's error." If one discovers the balance in one's bank account is too low, one is likely to complain to the bank. If one discovers the balance is higher than it should be, there is less incentive to complain.
