The results of these experi- ents were given in the work published by Mr. riggs in 1899, on the American School Building. hese experiments were conducted with a model 99 having about one-sixth the capacity of an ordinary^school room and the movements of the air weremade visible by mingling smoke therewith wherebyall changes undergone in the air were made
