Meteorological Observations for May 1827. 79 



two halos of this large diameter have been seen here the last eleven j'ears. 

 All these phaenomena appeared in lofty attenuated cirrostrative vapour, 

 lowered agreeably to the sun's descent, and slowly disappeared as the va- 

 pours moved off out of the refracting angles of the sun's rays. 



The atmospheric and meteoric phcenomena that have come within our 

 observations this month, are five parhelia, four solar halos, three meteors, 

 one double rainbow, lightning and thunder on three different days ; and 

 eight gales of wind, or days on which they have prevailed ; namely, one 

 from N.E., one from S.E., five from S.W., and one from N.W.
