Transactions of the Society of Motion Picture Engineers (1921). bringing this little talkbefore you was to interest you people in setting up such an apparatus,any sort of apparatus, and actually put different chemicals in the arc,and see how many varieties of phenomena can be obtained, a varietyof phenomena which will go far to getting at a great many secretsthat are now concealed in nature.
