The Languedoc Canal was the first important one constructed (between 1607 and 1681) in France, and connected the 

 Bay of Biscay with the Mediterranean ; thus avoiding the long detour by the Strait of Gibraltar. ' It proved the proto- 

 type of the modern ship-canal, though, as its depth is only 6 feet, it is not adapted for vessels above 100 tons. The 

 Gironde and the Garonne give access up to Toulouse; and from this point, the Languedoc Canal, or Canal des deux Mers, 

 148 miles long, rises gradually by locks to a summit level of 600 feet at Naurouse, and then descends in a similar manner 

 to Xarbonne on the Gulf of Lyons, the number of locks being 119.' Prof- L. F. Vernon-Har court.

 5th Edition, revised and considerably abridged by the Author, thick 8vo. cl. (o. p.), 7s 6d (p. 18s) 1874 



The author's great contribution to the reconciliation of religion and science is that, ' on the authority of the immutable 

 word of God, from which, assisted by the discoveries of science, there can be derived the necessary data to prove, during 

 the period called in scripture ' the beginning ', the earth had, in reality, no diurnal rotation around its axis. 'Introduction.

 Remarks on RAILWAY ACCIDENTS, and Proposals for their Prevention, 64 woodcuts, post 8vo. cl. 

 (SCARCE), 8s Qd 1846 



Interesting as having been published during the height of the Railway Mania. ' Parliament, during the recent session, 

 has with very great liberality passed bills for railways to the enormous extent of 2841 miles, with a capital of 44,322,235.' 



It deals judiciously with the strange 'atmospheric' fallacy, and with the happy-go-lucky railway accidents of the 

 time, of which many queer examples are given.
