though it is going a little outside of the purpose of this paper, 
I venture to suggest that until investigation shall determine the 
matter, it be regarded as an open question, whether the starva- 
tion process may not be advantageously applied in a practicai 
way to the weeding out of weak fish from our broods. 
To sum up conclusions, 1 think the data here laid before you 
warrant us in concluding that fasting, carried to the extent of 
incipient starvation, though “t may greatly retard the growth of 
fry and fingerlings in their early stages and produce actual em- 
aciation, does not permanently stunt them but leaves with them 
the capacity of attaining normal size by rapid strides when placed 
under favorable conditions.
