 Bischof, of Bonn, in testimony of the high esteem in which the 

 Fellows of the Geological Society of London hold his services to 

 geology, more especially as shown in his work entitled ' Lehrbuch 

 der chemischen und physikalischen Geologie'* — a book known and 

 valued by the physical geologists of the whole world, and which, as 

 the first great work on the subject, now renders, and in future times 

 will still render, the name of Bischof classical in geology. 



Mr. Horner replied as follows : — 



Mr. President, — It will give me much pleasure to forward this 

 Medal to my old and distinguished friend, as an honour so well 

 merited by long and great services rendered to an important depart- 

 ment of our science. It is now more than thirty years since I had 

 the advantage of becoming personally acquainted with Professor 

 Bischof, during a long residence at Bonn. He was then actively 

 engaged in those observations in the field, and experiments in his 

 laboratory, by which, through the labours of many years, he has 

 thrown so much light on chemical agencies concerned in the forma- 

 tion of mineral substances, in the phenomena and products of vol- 

 canos, and in filling mineral veins. It was about that time that he
