My personal belief is that the red clays are Carboniferous, and the 

 breccia bed Permian.

A NOTE ON ISOSTASY. 

 Sir, — I am much indebted to Mr. Anderson for calling attention 

 to the oversight in my calculation. His re-calculation is perfectly 

 right. Consequently, instead of 1,100 feet as the possible thickness 

 of sediment accumiilated in a sea of 100 fathom depth, we have 

 1,872 feet; or in the improbable case of a density as low as 2-7 for 

 the supporting column, as much as 3,000 feet. These figures are 

 still far removed from those great thicknesses of shallow-water 

 deposit for which isostasy has been claimed as an adequate 

 explanation.

GEORGE JENNINGS HINDE,

(WITH A POETEAIT, PLATE X.) 



As a worker gleans in a cornfield after the crop has been harvested, 



I have endeavoured to collect some records of my friend George 



Hinde, whose life's work terminated in March last. He was 



a Norwich boy, like myself, and went to the Grammar School there, 



but being my junior by seven years we never met until many years 



later, our paths in early life lying wide apart. 



George Hinde was the third son of Ephraim Hinde and grandson 

 of the founder of the firm of Ephraim Hinde & Son, Paramatta 

 manufacturers in that city. His father lived near his ISTorwich 

 factory, but in 1847 bought a farm at Catton, where he and his 

 family resided. George's mother died when he was 13 years 

 old, and at 16 his father sent him to learn farming in Suffolk 

 with a Mr. Spelman, where, being a studious lad, he spent his 

 leisure hours in acquiring Latin, French, algebra, physics, and 

 chemistry. About this time he heard a lecture by the Eev. IMr. 

 Blowers on "Hugh Miller", which greatly interested him, and he 

 bought and read Hugh Miller's books, and thus his mind was first 

 directed to the study of geology. 



When 18 years of age he commenced to farm his own land at 

 Bawburgh, near Costessy, Norwich. Early in 1862 he attended 

 a series of lectures in Norwich by William Pengelly, F.R.S. ; these 

 further stimulated his desire to take up geology, Avhich later on 

 became the leading ambition of his life. In the same year he paid
