    introduced the diminution was very con- siderable. These appearances induced me to change my apparatus, and m*tke more accurate trials. A small quantity of sul- phur was introduced into a glass tube a foot long, curved as the former; the sub phur was made to adhere to its extremity by fusion ; when cold, it was filled with mercury, and a cubic inch of oxygen gas Avas thrown up ; and the space, occupied by the gas in the measure used, was accu- rately divided into twelve equal parts. When sufficient heat Avas applied, the combustion of a portion of the sulphur was effected with a sudden tiash, accom- panied with a considerable concussion, similar to Ayhat takes place when oxygen and hydrogen are fired by the electric spark. In about a minute after, a second explosion took place, and a languid blue flame appeared on the surface of the fused sulphur, which lasted a few seconds. ISo further change Avas produced by a continuation of the heat, although the end
