An historical example of an analogy used by a scientist:
Bordet* said that just because twice as much serum is needed to combine with two as with one dose of bacterial emulsion, some bacteriologists argue that antigen and antibody must combine according to a law of definite proportions. That, he said scornfully, was like claiming that paint must react in definite proportions with a wall. The regular chemical law of definite proportions need not apply.
