This- proved to be the finest head of bos primigenius ever discovered. 

 It became entangled in their fishing net in the river Avon, near 

 Melksham. The frontal bones ^'ith the horn cores were quite 

 perfect and measured in breadth, without including the curvature 

 of the 'cores, four feet, and when clothed with their horns they 

 must have been still wider. Ten shillings would then have pur- 

 chased the specimen, but as I had not become a "natural

 This head was figured and described by Mr. Wood, of this city 

 and is now in the Town-hall of Melksham. The land and fresh

 identical with those in the bed below, from which a list will be

 No notice was taken at the time of any fi-esh water marls or 

 gravels at the top of this section, though doubtlessly they 

 were present. The beds Nos. 1 and 2 belong to the lower lias ; 

 Nos 3 4 and 5 are now separated from the lias and constitute 

 members of the rh^etic series, the "dark red soil," No. 6, being 

 without doubt the upper portion of the Keuper, or new red sand-
