JLT is a fact long established, that tw6 rain gauges, placed 

 at different heights^ afford unequal products; the lower 

 commonly yielding more than the higher. The following 

 table gives the results of observations on this subject made

 the elevation or depression of the mean temperature and 

 direction of the prevailing wind being added.
