"at once be apparent how very largely the saving of infant life was due
"to the reduced mortality experienced in the third quarter of the year;
"for while the mortality in the first quarter was 4 per 1,000 above the
"average, and only 10 and 12 per 1,000 below the average in the second
"and fourth quarters, it was no less than 107 per 1,000 below the average
"in the third quarter."

"From the foregoing statement it will be observed that the greatest
"variations in the rates of infantile mortality occur in the third quarter
"of the year, and that these wide fluctuations are coincident with changes
"in the summer temperature and rainfall. In order to further exem"plify
the effect of climatic conditions on infant life the tabular state"ment
below has been prepared showing for the past 38 years the rates
"in the third or summer quarter of each year, together with the mean
