The book to which Colin Hinz referred in yesterday's message is:

Componium: the mechanical music improvisor, by Philippe John van
Tiggelen -- published by Institut Superieur d'Archeologie et
d'Histoire de l'Art, Louvain-la-Neuve, 1987.

It runs to a hefty 462 pages (including a 32-page bibliography) and
according to my library's catalogue, 'includes information on the
Winkel-Maelzel controversy about the history of the metronome'.

The copy to which I refer is in the National Library of Scotland in
Edinburgh where it will be preserved for the benefit of future
generations of scholars.  So if anyone is visiting Edinburgh they can
be sure of being able to see it.
