 prize ottered by Parliament for llnding the longitude at sea. By Act of Parliament Mayer's widow was awarded £300<). 



' Mayer was the Hrst who constructed lunar tables of surticient accuracy for the great practical purpose of tinding the 

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

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

 organische Bewegung in ihrem Zusamnienhange init dem Stoffwechsel ', ' Ueber das Fieber ', and ' Bemerkungen iiber 

 das mechanische Aequivalent der Warme '. The last, which was originally published in Liebig's Annalen in 1842, or 

 5 years before Helinholtz'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 

 18G2, in a lecture before the Royal Institution. 



So little was then known of its author that Poggendorfl!" stated in his Handworterbuch in 18G3 that he was ' supposed 

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

 of the merits of his work.

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

 Lavoisier) by liis 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 aftinity, and a mechanical e.xplanation of the act of jumping.
