' The experiments described in this paper were undertaken to ascertain whether solids have definite volatilizing points 

 under different pressures, as liquids have definite boiling-points and whether the.se pressures are identical with their 

 vapour-tensions at those temperatures '—P. 1.

' In the preface by Maskelyne it is stated that he received £315. from the Government by way of premium for this 

 important invention, and £300. for his property in it ... A duplicate of his dividing-engine was said to have been 

 introduced by President Saron into France, concealed in the pedestal of a table.'— 3f<s.s Agtvs M. Gierke. 



This work is very rare, most copies having been destroyed in a fire in the printer's warehouse. See Lalande's preface 

 to No 13881 infra.

 ments, loith 3 large folding copperplates by J. Basire, 4to. (pp. 16), unbound, I2s 1779 



Both the above works were published by order of the Commissioners of Longitude. 



Ramsden was perhaps our greatest mathematical instrument maker, the son of an innk«^eper at Salterhebble, near 

 Halifax, and called by Delambre ' le plus grand de tons les arti.stes '. 'The demand from all parts of Europe for his 

 incomparable instruments was greater than could be satisfied bv the constant labour of sixcy workmen. His life was 

 one ot extreme frugality. His lavouiite scientific authors were Euler and Bouguer, and in advanced years he learned 

 French enough to read Boileau and Moliere. Most of his evenings were spent drawing plates by the kitchen fire, a cat 

 on one side, a mug of porter and plate of bread and butter on the other, while some apprentices sat round, and he whistled 

 or sang. In consequence of his disregard of gain he left but a small fortune, mostly divided by will among his woikmen.

' Un de ses plus precieux ouvrages est sa machine a diviser : la description, quoique imprimee, n'existe plus, ayant 

 ete consumee par un incendie. M. Shepherd, Tun des commissaires du bureau des longitudes, a bien voulu nie confler 

 son exemplaire. Cette machine, dont M. Ramsden s'est occupe pendant dix ans, a ete regardee comme un tresor pour 

 la marine angloise, et tons les artistes qui font des sextants pour I'observation des longitudes les envoient diviser chez 

 M. Ramsden.' — Preface.

 An early form of a range-finder, consisting mainly of a micrometer fixed to the eye-piece of a telescope. The inventor, 

 •a Lewes man, was encouraged by the Duke of York as Commander-in-Chief.
