Fred asked if that was the largest meteor ever found.
MELBOURNE AEROLITE.
"Not by any means," the Doctor answered. "The largest in any collection was sent from Melbourne, Australia, to the British Museum, and weighs 8257 pounds. The same museum has one from Otumpa, South America, that weighs 1400 pounds, and was detached from a mass estimated to weigh more than fifteen tons. This is the largest mass of meteoric iron known to exist.
STRUCTURE OF THE TEXAS AEROLITE.
"Meteoric iron has a highly crystalline formation, which can be found by polishing a surface and then heating it to whiteness. When it is cooled it will be found covered with curious lines and streaks that remind you of the frost-marks on a window-pane. An aerolite found in Texas was submitted to the heating process; the streaks that were developed remained there permanently, and the same is the case with several others. Ordinary iron will not exhibit these marks, but they can sometimes be produced in iron that has been melted out of volcanic rocks."
"How does the iron get up in the atmosphere to form these aerolites?" one of the boys inquired.
