The vapor frequentlycondenses on the globe on its way down,forming what is usually called circulation makes a light very weak,and causes it to crust over more or lessrapidly, according to the degree of colder the weather, the quicker itcrusts over. A light under these condi-tions is always weak, and any motionwhich will cause these gases to envelopthe wick for an instant, will immediatelyextinguish the flame. The ventilating holes, as well as inlets,are not protected sufficiently against thewind, and the light, being weak, can beblown out easily. The cause of all thisis, first, that the ventilation is not suffi-cient to carry off the products of combus- Air Currents Course of Gases.
