    Description
    A map of Rosneath bay and musical notation.

    At a meeting of the Royal Society on 3 December 1662, Robert Moray reported that he got a trumpeter at a low ground, A, facing toward C, a house built of stone, 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. F is the head of the lake, and H, the ‘fair house’ at Rosneath, outside Glasgow.

    Other versions of this image can be found at RBO/2ii/049, RBO/2i/053, Cl.P/2/34/003-04 and RBC/1/266. Another version of the notation without the map can be found at MS/92/043.

    This volume is another copy of entries of the first two volumes of the Register Book. It was given to Sir Joseph Banks by G. S. Heales Esquire of Doctor's Common on 31 May 1814.
