1 I was for a long time unable to procure a sight of Prof. Cantoni s 

 valuable papers, but he has lately been kind enough to send them to me. 

 Having merely seen references to them in journals, I was led on a 

 former occasion ('Nature/ No. 48, 1870, p. 43^) to state that he had 

 obtained positive results at 242-6" C, instead of 242-6° F. I mucn 

 regret that the mistake should have occurred.
