TSE REVIVAL OF ORGANIC CHEMISTRY.* 

 Custom Las placed upon the presidents of 

 the Chemical Society the duty of delivering 

 an annual address, and in pursuance of that 

 dutjr I spoke to you last year upon the ' Ee- 

 vival of Inorganic ChemistrJ^'f I endeav- 

 ored to show that this branch, so long over- 

 shadowed by organic chemistry, so long but 

 little more than a collection of almost un- 

 connected facts, subordinate to analytical 

 and technical chemistry and to mineralogy, 

 is gradually, and especially since the dis- 

 covery of the Periodic Law, rising to the 

 rank of an independent and important di- 

 vision of our science. 



I have chosen for my present topic one 

 which is complementary to the former, ' The 

 Revival of Organic Chemistry.' I may 

 perhaps appear to most of you almost face- 

 tious in speaking of the revival of a branch 

 of chemistry which has been in rapid growth 

 for so many decades, which never counted 

 a greater number of adherents than to-day, 

 and which, regarded from the systematic 

 standpoint, is not only the most highly de- 

 veloped portion of chemistry, but also one 

 of the most highly developed of all the 

 sciences. Yet I believe that the use of 

 the term revival is justifiable. I do not 

 share the opinion which appears to be 

 held by some inorganic and physical chem-
