in articles and other items in Scientific American.
We begin this reader with an article touching on the

reaction to them. This reaction is revealed in part by the
coverage of Halley s Comet at its last apparition in 1910
--coverage which included descriptions of the recovery
of the comet and of Halley s original work
"An introduction to cometary astronomy precedes
this collection of Scientific Arherican articles.
This introduction will help the reader to appreciate the
~ -~-development of cometary astronomy, its present state,
