An electrical treatise ' sous la Forme Scholastique ' would have tickled Father Tyrrell, ejnsdcm Socirtaiis. 



It is a very interesting work, full of original observations. In one on page 94 the author anticipates the electromagnetic 

 theory of light : ' Le feu, la lumiere et 1'electricite dependent du meme principe, et ne sont que trois modificatk ns 

 differentes du mome etre.'

' Pavy was the last survivor of a line of d^tinguished physician-chemists who did much to lay the foundations and 

 advance the study of metabolic disorders. He made the study of carbohydrate metabolism the work of his life, and he 

 was the founder of the modern theory of diabetes. In this connexion his name was associated with many practical im- 

 provements in clinical and practical medicine, and ' Pavy's Test ' for sugar and his use of sugar tests and albumen tests in 

 the solid form have made his name familiar to physicians throughout th^ world.' Prof. d'Arcji Power.
