curve in one direction, and suggesting the influence of a rotary motion 

 of the stone on its short axis. 



Of the smaller stones, one (shown in two positions in the sketch) 

 was a section of a perfect oval cylinder, cut at right angles with nearly 

 perfect edges. 



Nearly all of the stones observed were semi-transparent, and showed 

 a whitish ring in the centre, generally oval, but sometimes circular. 



Forms of Hail Stonks. 



Inside and outside of this ring they were usually clear, but some had 

 also a whitish nucleus in the centre. Some of the smaller ones were 

 whitish and opaque throughout. The stones were examined while the 

 hail was yet falling, and were taken from some young grass where 

 they were not liable to be broken in the fall. From persons at other 

 points in the city I learned that the distribution of the hail was very 

 singular, at some points scarcely any being noticed.
