Details
Peter Legaux owned a farm and vineyard at Spring Mill, thirteen miles northwest of Philadelphia. Legaux kept detailed meteorological records between 1786 to 1827. His observations were included in the ‘Universal Asylum and Columbian Magazine’, from which Hutson included them in his Supplement.
Legaux's readings only give the mean temperature for each day, as well as the highest and lowest temperature readings for each month. It is also worth remembering that his information was recorded some distance from Philadelphia.
