TO CORRESPONDENTS. 



The Drawings of the Spots on the Sun will be acceptable. 



We are authorized to announce the intention of Dr. Prout to reply 

 in our next Number to the remarks of Drs. Tiedemann and Gmelin, a 

 translation of which is inserted in the present Number. 



The length of several articles has obliged us to defer till our next a 

 notice of Dr. Harwood's useful work " On the curative influence of 

 the southern coast of England." 



M. Fayolle's communication has been received. 



We have to thank Prof. Hare for his communication dated May 24. 



Veritas, in reply to the adimadversions of a |3 on Mr. Herapath's 

 papers is under consideration. Calmness should be a characteristic of 

 Truth ; and we are not pleased when our correspondents lose their tem- 

 per. Our duty of seeing fair play in scientific discussions seems to require 

 us to state that Mr. H. or his advocate ought to have met the objections 

 of a jS and F.R.S., p. 96 and 97 of our last volume, before they took up 

 any new ground.
