If on the horizontal line OA (the line of abscissae),we set off from its origin 0, a length proportionate to theamount of the fall, and draw a perpendicular to OA at thepoint so determined, the comparative frequency of falls ofthat amount will be shown by the length of the perpendicu-lar (the ordinate) between the base line and its intersectionwith the curve. The curves bear a general resemblance tohyperbolas. Were they true hyberbolas, the lines OA, OB,being their assymptotes, this would indicate that the fre-quency of a fall of given amount is inversely as its quantity,or, otherwise expressed,
