[27] This query refers to the circumstance that at the time Lady Roscoe was growing _Dictamnus Fraxinella_—the so-called “burning bush”—for the writer, who had undertaken to investigate the cause of the phenomenon which has given the plant its trivial name. The ready inflammability was found to be due to the accumulation in the vesicles on the flower-stems of small quantities of an essential oil.
