Vapours of Phosphorus, Lucifer Matches

Antibacterial action of anaesthetic vapours.

A permanent alternative is to re-site the fresh gas inflow to the back of the absorber where it has always been positioned in the past. With the elimination of the fresh gas flow error, it is found that respirometers placed at the catheter mount and in the circle give almost identical readings with spontaneous respiration. With controlled respiration there is over-reading of the circle respirom...

Do Weave Matches Imply Canvas Roll Matches?

Computational algorithms for measuring thread counts from scanned x-rays produce warp and weft thread count “maps” across entire paintings. Within the database of over 300 van Gogh paintings, we found a clique of 44 warp-weave-matched paintings. By reconstructing the smallest canvas section that could have produced this match, they must span the entire width of a commercial canvas roll (2+ mete...

On narcotism by the inhalation of vapours

produced a thorough and sensible study which will become the standard reference work on garum and salted fish in the Roman world. There is now no excuse for ignoring their dietary importance in the ancient world, and it is to be hoped that Curtis or someone else will take the study of this aspect further. The Greenland mummies, first published simultaneously in Danish and Greenlandic in 1985, i...

Thermocamera studies of gases and vapours.

Most gases and vapours with a bipolar molecular structure absorb infrared energy. If such a gas is interposed between an object emitting infrared radiation and a thermocamera the gas will absorb some of the infrared radiation and thus cast a shadow on the thermocamera picture. In this assay it is possible to visualise the gas. This method had been used to study pollution with anaesthetic gases ...
