HAVING been accuftomed to keep (for the purpofe ofoxigenand 



deflagrating) a mixture of oxigen and hidrogen gales in the h,d r°§ e » mixed

proportion as nearly as I could guels that would form water, 1 an j nv erted 



was much lurprifed upon inverting a quart bottle of fuch a bot !e with a

mixture in a pneumatic tub, to find the water immediately rile ed during 



up and fill it; as I could only account for it by fuppofing water three months 

 had been formed from its conftituent parts, or that the gafes **^ va * 

 had efcaped from the bottle and left a vacuum. Either fup- 

 pofition appears to be attended with considerable difficulties; 

 for what nice pay of the affinities could occafion the abftrac- 

 tion of that portion of caloric which is eflential to the aeri- 

 form irate of the gafes, and mult be before water could poffi- 

 bly be formed ; and on the other hand, if the gafes had made 

 their efcape at the cork, what prevented the atmofpherical 

 air from entering ? The bottle containing the gafes had been 

 left inverted in a common bottle rack with a fmall quantity of 

 water in its neck for about three months.
