Which Weighs the Most, the Egg or the Chicken 
which Comes From the Egg? 
Cc. A. WHITING, SC. D., D. O. 
This question has been guessed at a number of times, but I do 
not remember ever having seen exact data given in regard to the 
matter. With a view of answering the question with scientifie 
exactness, Dr. J. O. Hunt, of Los Angeles, carried a fertilized 
and an unfertilized egg through the whole process of incubation 
with the results given below by the eggs indicated by A and C. 
More than a year after Dr. Hunt’s experiments, I carried eggs 
B and D through the same treatment. The tabulated results 
are here presented.
