ETHERIZATION. 



The following communication from Dr. Charles T. Jackson- 

 cannot fail to be interesting to our agricultural friends, as well 

 as others. From the testimony which we have examined there 

 is no room to doubt the fact that Dr. Jackson w^as the original 

 discoverer of this important agent in alleviating the sufferings of 

 mankind under painful operations in surgery ; and it is a mat- 

 ter of congratulation that through the perseverance and humanity 

 of the Doctor, its benefits have been extended to domestic animals. 

 If any proof Avere w^anting to substantiate Dr. Jackson's claim to 

 the originality of the discovery, we think the most fastidious 

 ■would be satisfied when it is known that the government of 

 France constituted him a Knight of the national order of the 

 Legion of Honor, for this very dicovery, on the report of the 

 Academy of Science of that nation, l)efore which his claim was 

 subjected to the most searching scrutiny. He received also the 

 medal of merit from the King of Sweden, where hi? claim under- 

 went a thorough examination. A. C. 



To A. Chandler, Esq., 



Corresponding Sec^y of the American Institute : 

 S]R. — As you requested, I have employed a few leisure mo- 

 ments in drawing up a statement relative to the application of 

 the vapor of sulphuric ether and chloroform mixed with air, 

 administered by inhalation into the lungs, as a means of render- 

 ing man and animals free from all sensation of pain in surgical 

 operations, which I place at the disposal of the Institute. 

 Respectfully Yours, 



CHARLES T. JACKSON, M. D.
