english: Haldane guesses that a dog would probably be able to place the acids in the order of their molecular weights by their smells, just as a man could place a number of piano wires in the order of their lengths by means of their notes.
non_english: Holden odhaduje, že psy by pravdepodobne vedeli usporiadať kyseliny podľa ich molekulárnej váhy na základe ich vôní, presne tak, ako dokáže človek usporiadať struny v klavíri podľa dĺžky za pomoci ich tónov.
