AND SCHONBEIN 73 



in which case I shall take the liberty of paying my 

 respects to you in person. 



With the greatest esteem, 

 I have the honour to be, my dear Baron, 



Yours most sincerely, 



C. F. SCHONBEIN. 

 BALE, 1st March 1845. 



The following letter was written to Berzelius three 

 weeks later, and communicated to the Royal Academy of 

 Stockholm at their meeting of April the 9th, together 

 with a letter written by Plantamour of Geneva on 

 February the 4th, describing Marignac's first work on 

 ozone. In this letter there is as yet no allusion to the 

 possibility of ozone being a form of oxygen. This was 

 first suggested in another letter of Plantamour's of the 

 20th of April of the same year, which was laid before the 

 Academy on the 21st of May, and printed in the Ofver- 

 sigt, Arg. 2 (1845) p. 116. 



XV 

 Schbnbein to Berzelius 



MY DEAR BARON, 



I believe I have at last succeeded in solving 

 the ozone riddle ; and I think you and your colleagues 

 of the Eoyal Academy, as you have attached some 

 importance to the subject, will find the following 

 communication worthy of your attention.
