In this section are farther considered the inflections or “ periodic 
anomalies” of the annual curve. When the normal curve deduced 
from the preceding equation (p. 295) is projected and compared 
with that which the projection of the daily temperatures produces, 
the latter is found to fluctuate considerably, and to pass in an irre- 
gular manner, sometimes above, and sometimes below, the geo- 
metric curve, which, however, fairly represents the totality of the 
observations. 
We find, however, that there are deviations from the average or 
normal curve, which occur at certain seasons, and which do not appear
