HOROLOGIUM OSCILLATORIUM. The Pendulum Clock.

Horologium Oscillatorium, the Pendulum Clock, lies to the eastward of Achernar, — α of Eridanus, — and north of Hydrus.

Although shown on the maps, it is rarely mentioned; and the only object in it known to be of special interest is a variable star, detected by Harvard observers in Peru, changing in light from 9.7 to 12.7 in a period of about three hundred days. Gould catalogues 68 stars down to the 7th magnitude; α, the lucida, being 3.8.

Whitall had on his planisphere a figure, which he entitled Horoscope, between “Chemica Fornar” and “Caela Sculptoris,” but no Horologium. His title is undoubtedly for our constellation, as it occupies Horologium’s place. ^[1]
