208 Meteorological Journal kept at Penzance. [Marc, 
meriting a place in your Annals, I regret that the account 
I.now send you is not more complete; yet I apprehend, om 
comparing it with any of the published meteorological journals 
of last year, it will be found to uphold our claim, not only toa 
superior degree of mildness of climate, butalso to a considerably 
greater equability of temperature. $ alo 
Should you think it of sufficient importance to merit publica- 
tion, it will, | hope, be in my power hereafter to transmit you 
annually a much more perfect and comprehensive view of our 
very peculiar Cornish climate. 
‘The height of the thermometer (a common Fahreuheit’s) has 
hitherto been noted only twice a day; viz. between seven and 
eight in the morning, and at two, p.m.; the followimg table 
must not, therefore, be considered as giving the actual maxima 
and minima observable throughout 24 hours, , but only the eleva- 
tion observed at the particular times stated. In like manner, 
the mean column gives merely the mean of these two observa- 
tions.. 1 am, dear Sir, with much respect, 
Your obedient humble servant, 
Joun Forsss.
