The observations made at Villa Nova, if compared with those made in England,

ture, and may be adduced in confirmation of the explanation given under Section 1,

7 . Of the Effect of Excited and Sustained Attention on the Temperature. 
A few instances may suffice to illustrate this effect, selecting those in which it vvas 
most strongly marked ; between which and those least notable there is a fine grada- 
tion, according to degree of exertion of mind, which it would be difficult to appre- 
ciate on account of interfering disturbing circumstances.
