The experiment can be performed in acheaper and less dangerous fashion by dropping phosphateof lime into the basin. We strongly recommend the lattercourse to the student unless he has had some practice inthe handling of these inflammable substances, and learntcaution by experience. The effect, when the experimentis properly performed is very good, the smoke rising in asuccession of coloured rings.
