It also contained nitric acid, apparently under 1 per cent., but 

 this was not accurately determined. 



Numerous experiments were tried to obtain some method of 

 determining the boracic acid. Although no good one was found, 

 I think a close approximation to the real quantity might be ob- 

 tained by adding, drop by drop, a standard solution of chloride 

 of barium or calcium as long as a precipitate is formed ; for as 

 soon as the liquid has become saturated with the borate, a very 

 small quantity of the precipitant occasions a distinct precipitate. 

 Circumstances prevented my continuing these experiments as I 

 should have liked. 



The hygroscopic water was not determined.

It is difficult to say whether the sulphuric acid is combined 

 with lime or soda, or both, as both sulphate of lime and soda 

 are found in the same district ; and glauberite (NaO SO 3 + CaO 

 SO 3 ) occurs crystallized in the very centre of many of the rounded 

 masses of Hayesine. It is most probable that it occurs as the 

 latter compound, a few small crystals of which might have escaped 

 detection in the selection of the sample. It will be seen that 

 this analysis, though imperfect, points to the formula given it by 

 Ulex.

THE following investigation is intimately connected with the 

 volatile body which makes its appearance during the elec- 

 trolysis of water, and which is usually known by the name of 

 ozone. As this, although without any positive proof, is gene-
