A waitress scurried up and helped move the dishes and teacups aside. Judge 
Fang unrolled the page and anchored it with various small items of faience. The 
paper was divided into two panes, each containing a magnified view of a 
microscopic device. Judge Fang could see that both were made to navigate 
through the air, but beyond that, they could hardly have been more different. 
One of them looked like a work of nature; it had several bizarre and elaborate 
arms and sported four enormous, wildly involuted, scooplike devices, arranged 
ninety degrees apart.
