...discharges of electricity on the spectra of various gases. Although great care was taken in drying and pur fying these gases, it was found that hydrogen, nitrogen and rarefied air gave substantially the same spectrum under the same conditions and as a result of the powerful electrical discharges the aqueous vapor was released from the walls of the spectrum tubes. From this investigation it was concluded that oxygen does exist in the atmosphere of the sun. It was also found by a similar study of aqueous vapor in the X-ray phenomenon that, probably by varying the conditions...

...purpose of these lectures will be to correlate as far as possible the newer ideas concerning the nature of aqueous solutions and the molecular conditions prevailing in them with the physiological phenomena they call forth, especially in plants. Since the study of the poisonous effects produced by these solutions has thus far received most attention from botanists, this class of phenomena will be dealt with in some detail...
