I will illustrate this action by making some artificial fogs in a bell-jar furnished with a metal point.
By the vivid combustion of phosphorus in a stream of dry atmospheric air, or under a bell-jar, copiously supplied with dry air.
Sometimes it will be necessary to cover the plant with a bell-jar in order to prevent it from drying before the spores are shed.
In the very middle of the bell-jar of visibility granted them all at once, stood a black rectangular object.
The solution, evaporated in a bell-jar over sulphuric acid, yields crystals which are neutral.
Page 226 then the specimen must be covered with a bell-bar or other receiver Changed to 'bell-jar'.
I also left others in a watch-glass, which was placed under a bell-jar enclosing several ferns.
Next fill a bell-jar full of steam, and electrify, paying attention to insulation of the supply point in this case.
I cover this sheet with a bell-jar standing in a depth of water.
The filtrate is then placed under a bell-jar over concentrated sulphuric acid until its volume is considerably reduced.
