14 Dr B(yu£s Observations on the 



tireinent among a beloved family. The pains of the gout alone 

 sometimes interrupted his tranquillity, and caused him the 

 greatest of his disappointments, by preventing him from going 

 regularly, as he had been accustomed, to hear his fellow-members 

 at the Academy, for there he was as constant as he was silent. 

 In his family he was as modest and mild as in the world. 



At length he slept the sleep of thejust, on the 19th February 

 1816, aged somewhat less than 86 years. A son, one of his most 

 distinguished pupils, and inspector-general of the mines, revives 

 his name in the career on which he first entered, and in which 

 this son has already made not less remarkable progress than his 

 father.

In the memoir of the two active members of the Geological 

 Society of London, we were pleased to observe, that they had 

 described and classified the various alpine deposites nearly in the 

 order which we pointed out in our papers in the Edinburgh 

 New Philosophical Journal for 18^0, and in the Zeitschrift 

 fiir Mineralogie von Leonhard, for 1829, and in the Journal 

 de Geologic, Nos. I. & II. for 1830. Nevertheless, they have 

 omitted some parts of the geological history of the Alps ; or, at 

 least, they hardly notice some of the prominent subdivisions of 

 these formations, which certainly would not have escaped them 

 had they allowed themselves sufficient time to take a more ex- 

 tensive view of that immense chain. As we are of opinion that 

 the structure of the calcareous arenaceous chain of the Northern 

 Alps presents peculiarities unknown on the southern side of the 

 Alps, we could have wished that the authors in question had 

 separated entirely the descriptions of each of these chains, be- 

 cause the intermixture of local details, sometimes from the one 

 side, sometimes from the other side, are apt to deceive the read- 

 er, and induce him to believe that if a complete identity does
