On the 26th May, the wind which had been blowing steadily from S., and 

 by E. suddenly veered round at 12K. 30m. to N. W. blowing very strongly, and 

 in heavy gusts varying in pressure from 3 to 25ios per square foot till 2h. 15m. p. m. 

 when it became calm, having veered during the interval by W. to S. W. About 

 37i. 30m. the wind again changed suddenly from S. W. to N. and by E. and 

 subsequently to E. and by N. The gale was accompanied by a good deal of 

 thunder and lightning and a little rain. The ten minutes observations taken 

 during the gale show that at Noon the Barometer stood at 29.79 Inches at 

 12 h. 30m., the moment of the first sudden change of wind, and commencement 

 of gale, it rose to 29.83 Inches and then fell gradually and continuously to 

 29.738 Inches at 5 p. m. At 8 p. m. it again rose to 29,832 Inches.
