A thin girl

I met a beautiful girl last night, but she was rather thin. I mean this is a skinny girl. You never saw anybody so thin. She turned sideways you didn’t see her. I took her to a restaurant and the maître'd said to me, 'Can I check your umbrella?'

James Pollard Espy

Died 24 Jan 1860 at age 74 (born 9 May 1785). American meteorologist who was one of the first to collect meteorological observations by telegraph. He gave apparently the first essentially correct explanation of the thermodynamics of cloud formation and growth. Every great atmospheric disturbance begins with a rising mass of heated, thus less dense air. While rising, the air mass dilates and cools. Then, as water vapour precipitates as clouds, latent heat is liberated so the dilation and rising continues until the moisture of the air forming the upward current is practically exhausted. The heavier air flows in beneath, and, finding a diminished pressure above it, rushes upward with constantly increasing violence. Water vapour precipitated during this atmospheric disturbance results in heavy rains.[Image: Formation of a thunderstorm, mature stage]
