in search of coal. Subsequently it has been 

 announced that there appears to be a great 

 similarity in the character of the Palaeozoic rock 

 which was formerly pierced on Lord Cadogan's 

 estate, at Culford, Bury St. Edmunds, and that 

 reached at Harwich, with the cores brought up 

 from Stutton and Weeley. It would seem, there- 

 fore that Essex has been placed out of the regions 

 of possibility as a coal-producing area, although 

 it is possible, that the boring now being sunk at 

 Great Wakering, near Southend, under the advice 

 of Messrs. Whitaker and Holmes, may prove more 

 successful than those they have already made. All 

 honour, however, to those who have spent their 

 time and money in order to extend our geological 

 knowledge of the eastern counties. 



In addition to the borings which have been 

 dealt with, others have been made at Ashford and 

 at Chatham, both in Kent, neither of these, 

 however, having reached coal-bearing beds. In 

 the Chatham boring a great thickness of alluvial 



clay was found resting upon the Chalk. In this, 

 as Mr. Whitaker remarked in his paper before 

 the Geological Society, was discovered one of 

 the most remarkable fossils ever met with, viz., 

 the remains of an old Dutch man-of-war, 

 which in a dark period in our country's history 

 had forced its way up the Medway, and 

 threatened old England with invasion. Neither 

 at Chatham nor Ashford were Palaeozoic rocks 

 reached, but the former left off in Oxford clay at 

 965 feet, Geologists are now seeking knowledge 

 as to the depths of the ancient rocks south-west 

 of the metropolis, but with the exception of the 

 boring at Richmond, we are very much in the dark 

 with regard to them. Richmond gave us the base 

 of Jurassic beds at 1,239$ feet, and if the red and 

 grey clays and sandstones which then succeeded 

 eventually prove to be Devonian, we have here an 

 important link in our westerly geological chain,
