Topic: [Letter responding to a short item in Athenaeum, Issue 142, p. 446, on the estimated speeds of different birds in the air. The letter says the paragraph in question makes a common mistake. It does not take into account the movements of the wind. It is the same mistake as overestimating the speed at which a steam boat travels by discounting the speed of the wind]
