Maskelyne's preface, and the explanatory matter, are given in both Latin and English. 



FIRST EDITION of these celebrated tables, for which the author was recommended by Bradley as worthy to share in the 

 prize ottered by Parliament for finding the longitude at sea. By Act of Parliament Mayer's widow was awarded 3000. 



' Mayer was the first who constructed lunar tables of sufficient accuracy for the great practical purpose of finding the 

 longitude at sea. This he did by means of Euler's theory and a skilful discussion of observations.' Prof. R. Grant.

A treatise on surveying and surveying instruments, and according to Prof. Moritz Cantor ' the most important work 

 on its subject published during the second half of the 18th century '. 



11694 MAYER (Julius Robert v.) BEITRAGE zur DYNAMiKdes HIMMELS, inpopularer Darstellung, 

 erste Ausgabe, 8vo. hf. cl. (scarce), os Heilbronn, 1848 



In this work the author shows that the sun would long have lost his radiating energy were it not renewed by swarms 

 of meteorites constantly falling in. He also developed in it the theory of tidal friction independently of Kant, who 

 first propounded it. 



11695 Die MECHANIK der WARME, erste Ausgabe, 8vo. hf. morocco, with auto, of Prof. 



Lloyd Tanner, F.fi.S., 4s Stuttgart, 1867 



A collection of the author's works, viz., the above Beitriige, ' Bemerkungen iiber die Kriifte der unbelebten Natur,' ' Die 

 organische Bewegung in ihrem Zusammenhange mit dem Stoffwechsel ', ' Ueber das Fieber ', and ' Bemerkungen iiber 

 das mechanische Aequivalent der Warme'. The last, which was originally published in Liebig's Annalen in 1812, or 

 5 years before Helmholtz's paper (v. No. 9109, ante), first established the principle of the conservation of energy. It 

 remained neglected (and partly ridiculed) by the scientific world, until Prof. Tyndall called attention to its importance in 

 1S<52, in a lecture before the Royal Institution. 



So little was then known of its author that Poggendorff stated in his Handworterbuch in 1863 that he was ' supposed 

 to have died in a lunatic asylum in 1858.' JWayer actually died 20 years later in 1878, after a belated and tardy recognition 

 of the merits of his work. 



11696 MAYNARD (Henry N., manager Viaduct Works, Crumlin, Mon.) The VIADUCT WORKS'

 MEDICO-PHYSICI, with portrait, and 6 plates (2 folding), cr. 8vo. cl., 4s Edin., 1907 



Mayow may be said to have laid the foundation of anti-phlogistic chemistry (although it was not fully developed until 

 Lavoisier) by his theory of combustion contained in the first treatise. He was moreover the first to give a good physio- 

 logical explanation of the function of breathing, and the discoverer of the double articulation of the ribs with the 

 spine. He also gave a theory of chemical affinity, and a mechanical explanation of the act of jumping.
