created beings—and as their ultimate end, the cure of disease, the al- 
leviation of agony, and the prolongation of human life. Gentlemen of 
yourown valuable profession have given their testimony to the import- 
ance of your discoveries, and the Council feels pleasure in rewarding 
your zeal and talents*. To you, and all who, like you, are employed 
in these noble pursuits, all here will say with me, may God prosper 
your labours to His glory and to the happiness of His creatures. 
Mr. DANIELL. 
The continued intercourse that I have had with you in the Coun- 
cil of the Royal Society increases the pleasure which I experience 
in giving into your hands this Medal. Electrical Chemistry, at all 
times of great importance as giving us an insight into the most re- 
condite laws of nature, has now acquired additional interest by the 
practical purposes to which a Wheatstone, a Spencer, a Jacobi, and 
others have applied it. Its connection with magnetism seems to 
promise still greater discoveries than those that have already immor- 
talised a Davyand a Faraday. You have pursued this difficult branch 
of Chemistry with signal success, and the Council have approved of 
the recommendation of the Chemical Committee, that one of the Royal 
Medals should be conferred on you for the valuable papers which 
you have contributed to our Transactions. I trust that our future 
volumes may be still more enriched by the result of your scientific 
labours tf.

GENTLEMEN, 
i reply to Mr. Moyle’s inquiry contained in page 73 of the Phi-
