    13 By “ Leslie ” Burner. By “ Single ” Jet. 1st experiment.... 4 31 6-88 2nd do 5-09 4-96 3rd do 3-44 4-05 Mean .... 1-42 1.76 Then the proportion, 1-42 : -339 :: 100 : 23-76, shows that slightly above twenty-three and three-quarters per cent, of sulphur was lost because the “ Leslie ” burner was employed in- stead of the “ single” one ! If we take the means of M. Ellissen’s first and third experi- ments, we find that in the place of the above loss, we have a deficiency instead of 41 per cent, in round numbers from the same cause! Eor the difference between 5-46 (the mean of the “single” jet determinations) and 3’87 (that of the “Leslie” esti- mation) is 1-59, and 3‘87 : 1-59 :: 100 : 41-09. I consider this average to be much nearer the truth—first, because I never yet obtained otherwise, at the lowest, than from 16 to 20 per cent, of loss (as compared with the “single” jet) by using the “Leslie” burner; and secondly, because it so nearly corroborates the con- siderable number of experiments given in the above tables. Of the Method of Burning the Gas with the addition of an Appa- ratus I call a “ Desulphurizer, by which any Increase of Sulphur in the Condensed Products from the surrounding Atmosphere is entirely prevented. 9
