•»» A letter received from a friend in Philadelphia, says, under date Fourth 

 Month, 3d, " After some days of tine spring weather, we yesterday had a snow 

 storm of 10 hours continuance, which covered the ground about five inches deep ; 

 but the weather is again mild, and the snow has nearly disappeared." 



The reader is desired to compare with this account the changes from warmth to 

 cold experienced tcith us in the early jjart of this month ; and, in particular, the 

 depression of the teuiperature by i;ighl (or minimum) between the 2d and 3d ; and 

 that by day, between the 5th and 6th of the month, which was continued through 

 several days following.
