The results thus obtained are shown in the following table : 



The following are the conclusions arrived at by Bellucci from the re- 

 sults shown in the preceding table : 



1. Since the papers are not colored alike in the dark and lighted por- 

 tions of the tubes, this reaction cannot be attributed to the ozone sup- 

 posed to be in the atmosphere passing through the apparatus. 



2. That since the papers in the lighted portions of the tubes, both at 

 the inlet and outlet of the apparatus, are similarly colored, the colora- 

 tion of the latter cannot be due to the chemical activity of the air caused 

 by its transmission over the green plants. 



3. That since the possibility of the presence of ozone is excluded by 

 the preceding considerations, the reactions in question prove the theories 

 of M. Cloez, who attributes the coloration to the complex and simul- 

 taneous action of oxygen and solar light independently of ozone. 



4. The fact that it is quite evident from these experiments that ozone 

 is not in'oduced by living plants, gives a value also to the results ob- 

 tained from the experiments with the parts recently cut, since it is well 

 known that the functions of the chlorophyll continues the same in the 

 cuttings as in the plants from which they are taken. 



Sausages colored with fuchsin. — The artificial coloring of meat has been 

 carried on to such an alarming extent at Jena as to attract the attention of 

 scientific men. The red coloration of fresh meat is due to blood corpuscles 

 or blood-coloring matter, which disappears upon the approach of decom- 

 position. This also takes place in smoking beef when the operation is 

 not carried on quickly, and want of this coloration is considered a sign 

 of poor quality. To restore this some of the dealers have made use of 

 fuchsin, and the consumption of meat treated with this substance has 

 in all cases been followed with injurious results. The results, which
