A quite similarly treated sulphur mass was analysed (also three 
days after its preparation) and contained 0.6 °/, of S,. 
Although this experiment has been carried out with a not irre- 
proachably acting thermostat the result cannot be open to doubt. 
After a small rise a great fall takes place, whereas according to the 
theory opposed the essential conditions are wanting; hence this expe- 
riment also shows that the fact stated by Messrs. Smits and pr Leruw 
is absolutely unexplained by their interpretation, and that here quite 
new explanatory principles must be found. As to the question in 
what direction these should be looked for, I will not go into this 
although my research indicated some possible explanations; Dr. pr 
Leruw seems to occupy himself with it just now and I feel compelled 
not to communicate any investigations of which it is known to me 
that they relate to a subject on which somebody else is engaged. 
The above investigation has, therefore, led to the conclusion: 
a. that the change in volume of strongly supercooled sulphur, in 
tbe temperature range of 70°—95°, is different from that observed 
by Dr. pe Leeuw;
