Schbnbein to Berzelius 



MY DEAR BARON, 



In the course of my latest experiments on 

 ozone, I have obtained some results of a rather unusual 

 kind, which I think are not wholly without import- 

 ance to science. In particular I have succeeded in 

 producing a most remarkable change in a series of 

 organic bodies ; for example, I have converted sugar 

 into a resin, that is, into a substance soluble in ether, 

 alcohol, fatty oils, etc., but insoluble in water. One 

 of the most peculiar transformations that I have 

 effected is in vegetable fibre, which I have brought 

 into such a condition that it is readily soluble in 

 ether and alcohol, but unaffected by water, and if 

 properly prepared, possesses the transparency of glass. 

 On this change of vegetable fibre I have founded 

 a process which enables me to convert ordinary 

 unsized paper into a substance having the following 

 properties.
