Description

Moray reports on an echo experiment he carried out near Rosneath [Argyll and Bute, Scotland]. He placed a trumpeter at a low ground, A, facing toward C, a house built of stone, and asked him to play eight semibreves for about ten seconds. The first echo appeared to come from between B, a rocky precipice, and C; the second one from around D, a church; and the third echo from between D and E, another church. Includes a diagram of the locations in the experiment as well as a musical score of the tune played by the trumpeter.
