 PRESSURE to the Purposes of LOCOMOTION on RAILWAYS, with ^folding plates, and 2 woodcuts, 

 8vo. (pp. 50), sewn (SCARCE), 12s 6d 1841 



The author, the pioneer iron shipbuilder of the Isle of Dogs-, was with Samuel Clegg the elder the lirstto utilize George 

 Medhurst's suggestion to obtain locomotive power by differential atmospheric pressure, by constructing an exhaust railway 

 between London and Wormwood Scrubbs in 1840. The impossibility of maintaining a working vacuum however produced 

 an enormous coal bill, and the scheme came to an end, as mentioned in the next article. It had one final modified trial in 

 the system of the Pneumatic Dispatch Co., but their tube too has long been derelict, and the new Post Office Railway is 

 to have electric draught.

'A model of careful exposition, reminding one of the ' Algebra ' which Euler dictated after having been overtaken by 

 blindness. It contains an account of Euclid's doctrine of proportion, a good deal of what we now call mensuration, a con- 

 sideration of Diophantine problems, and of magic squares, and it finished with the solution of biquadratic equations.'

 Thomas Nettleton, Richard Wilkes, J. Boldero, Gervas Holmes, and others.

'At the age of 25 he was brought to Cambridge by Joshua Dunn, a fellow-commoner of Christ's College, with whom 

 he resided there, but he was not admitted a member of the College or of the University, owing to want of means. He 

 hoped to make a position as a teacher, and with the consent of the Lucasian Professor, William Whiston, formed a class, 

 to which he lectured on the Newtonian philosophy, hydrostatics, mechanics, sound, astronomy, the tides, and optics 

 . . . Lord Chesterfield, who was at Trinity Hall, 1712-14, and attended Saunderson's lectures, described him as a pro- 

 fessor who had not ths use of his own eyes, but taught others to use theirs. 'D. N.B.
