"Scheele, it was said, never forgot anything if it had to do with chemistry. He never forgot the look, the feel, the smell of a substance, or the way it was transformed in chemical reactions, never forgot anything he read, or was told, about the phenomena of chemistry. He seemed indifferent, or inattentive, to most things else, being wholly dedicated to his single passion, chemistry. It was this pure and passionate absorption in phenomena-noticing everything, forgetting nothing-that constituted Scheele's special strength."

Cats have a sort of game they play when they meet. A player alternates between watching the strange cat and ignoring her, grooming or examining everything around herself - a dead leaf, a cloud - with complete absorption. It is almost accidental how the two cats approach, a sidelong step and then the sitting again. This often ends in a flurry of spitting and slashing claws, too fast to see clearly, and then one or the other (or both) of the cats leap out of range. The game can have one exchange or many - and is not so different from the first meetings of women.
