and Delabeche'a map of 24 miles round Bath (a copy of which is 

 in the Institution), the " outlines " of Conybeare and Phillips, and 

 the Rev. B. Richardson, of Farleigh, " a gentleman long and 

 extensively known as a diligent and successful cultivator of 

 science." The district comprised is a large one. The formations 

 included in the circuit are from the lias up to the lower chalk. 

 He gives descriptions of the sub-divisions of each with their 

 thickness and the localities where they may be well seen. Accurate 

 measurements are given in inches of the sub-divisions as seen in 

 different quarries. His paper deals exclusively with the lithological 

 characters and relative positions of the divisions of the strata, 

 which in this part of the country are very strongly marked. At 

 the end of the paper is a list of organic remains, in which only 

 those found by himself are recorded, but he does not attempt 

 to distinguish characteristic forms from others. A reference 

 to the Mineral Conchology or some other standard work is 

 given with each species, together with the locality at which the 

 specimen had been found. Without any attempt to give a 

 resume of the contents of the paper, it may be interesting 

 to allude to the following paints. The sands, sometimes called 

 upper lias sands, are classed by him with the inferior Oolite ; in 

 the Fuller's earth he recognizes in the lower clay one or two strata 

 of tough rubbly limestone, Fuller's earth rock. At p. 254 he 

 gives a diagram showing the thinning out of the Great Oolite ; he 

 wished to class the Bradford clay with the forest marble ; he 

 regarded the sand and sandstone of the forest marble as a 

 representative of the Stonesfield slate of Oxfordshire ; he used the 

 terms for this part of the country adopted from Prof. Phillips 

 " Upper Calcareous Grit " and " Lower Calcareous Grit ; " and 

 the divisions Lower Green Sand, Gait, and Upper Green 

 Sand, which had been but just introduced. The value of his 

 example in following the orthodox way of spelling gait should not 

 be overlooked. He notices the existence of chalk flints on isolated 

 downs and hills in the neighbourhood of Bath, and gives a list of 

 mammalia found in the gravel pits at Larkhall. Although the 

 list of fossils has been largely increased since his time, yet the 

 paper itself, which was the first detailed description of the district
