deviating from regular paths, embracing such a combination . 
of changes, as to exhaust even the almost boundless powers 
of modern analysis in their representation. Those general 
phenomena which are represented®by the machine are enu- 
merated as follows: 
ing nodes—their apparent paths in the 
heavens, and their relative positions, for any given time, in 
relation to the fixed stars. 
Secondly. ‘The phenomena of the inferior planets, particu- 
larly their motions, direct and retrograde—their inferior and 
superior conjunctions—their elongations, transits, and the 
phenomena of the morning and evening star. : i 
Thirdly. ‘The phenomena of the change of seasons, of day 
and night, the varying declination of the sun, its rising and 
setting for different latitudes, its longitude, its amplitude, and 
azimuth, and its appearance, as well as that of the other heay- 
enly bodies, in a right parallel or oblique sphere. 
Fourthly. The phenomena of the diurnal motions of the 
heavenly bodies—the circles of perpetual apparition and oc- 
cultation—the rising, setting, altitude, latitude, longitude, 
and declination of the principal fixed stars—the constella= 
tions in which they ate dovannt Gini phenomena of the ap« 
pearance of different constellations at different seasons of the 
year. 
: Fifthly. The phenomena of the moon’s phases, in its va- 
rying position with regard to the sun and earth—its periodic 
and synodic revolutions—the inclination of its orbit to the 
great standard, the ecliptic plane—the retrograde motions of 
its nodes—its latitude and longitude, and the approximate time 
ofits rising, southing, and setting, for any given day and place. 
Sicthly. The phenomena of solar and lunar eclipses, and 
the time of flood and ebb, spring and neap, for any given 
place, by reference to the pesition of the sun and moon.
