DADDY-LONG-LEGS (27 まだ続きます)

                                           November 15th

Dear Daddy-Long-Legs,

    Listen to what I've learned today.

    The area of the convex surface of the frustum of a regular pyramid is half the product of the sum of the perimeters of its bases by the altitude of either of its trapezoids.
※面倒ですが、正角錘(正四角錐)の側面積を求める方法です。


    It doesn't sound true, but it is ー I can prove it !

    You've never heard about my clothes, have you, Daddy ? Six dresses, all new and beautiful and bought for me ー not handed down from somebody bigger. Perhaps you don't realize what a climax that makes in the career of an orphan ? You gave them to me, and I am very, very, very much obliged. It's a fine things to be educated － but nothing compared to the dizzying experience of owing six new dresses. Miss Prirchard who is on the visiting committee picked them out ー not Mrs. Lippett, thank goodness. I have an evening dress, pink mull over silk ( I'm perfectly beautiful in that ), and a blue church dress, and a dinner dress of red veiling with Oriental trimming ( makes me look like a Gipsy ) and another of rose-colored challis, and a gray street suit, and an everyday dress for classes.
