Sex also proves to be of little if any importance in such cases. It is interesting to note that the female of longest survival period (No. 5194) and one of the two males which survived nearly as long (No. 5191) were from the same litter, illustrating the desir- ability of "litter controls" in comparative experiments wherever practicable. Apparently family and individual variability are larger factors than sex or size among normal rats all of which are 28 or 29 days old and whose dietary histories are identical.
