bout by a single individual, but still achieved. Something of the laws
of cyclone and anticyclone are known, and rude weather predictions
across the Atlantic are roughly possible. Barometers and thermometers
and anemometers, and all their tribe, represent the astronomical
instruments in the island of Huen; and our numerous meteorological
observatories, with their continual record of events, represent the work
of Tycho Brahe.

Observation is heaped on observation; tables are compiled; volumes are
filled with data; the hours of sunshine are recorded, the fall of rain,
the moisture in the air, the kind of clouds, the temperature--millions
of facts; but where is the Kepler to study and brood over them? Where
is the man to spend his life in evolving the beginnings of law and order
from the midst of all this chaos?

Perhaps as a man he may not come, but his era will come. Through this
stage the science must pass, ere it is ready for the commanding
intellect of a Newton.

But what a work it will be for the man, whoever he be that undertakes
it--a fearful monotonous grind of calculation, hypothesis, hypothesis,
calculation, a desperate and groping endeavour to reconcile theories
with facts.

A life of such labour, crowned by three brilliant discoveries, the world
owes (and too late recognizes its obligation) to the harshly treated
German genius, Kepler.

SUMMARY OF FACTS FOR LECTURES IV AND V

In 1564, Michael Angelo died and Galileo was born; in 1642, Galileo died
and Newton was born. Milton lived from 1608 to 1674.

For teaching the plurality of worlds, with other heterodox doctrines,
and refusing to recant, Bruno, after six years' imprisonment in Rome,
was burnt at the stake on the 16th of February, 1600 A.D. A "natural"
death in the dungeons of the Inquisition saved Antonio de Dominis, the
explainer of the rainbow, from the same fate, but his body and books
were publicly burned at Rome in 1624.

The persecution of Galileo began in 1615, became intense in 1632, and so
lasted till his death and after.

Galileo Galilei, eldest son of Vincenzo de Bonajuti de Galilei, a noble
Florentine, was born at Pisa, 18th of February, 1564. At the age of 17
was sent to the University of Pisa to study medicine. Observed the swing
of a pendulum and applied it to count pulse-beats. Read Euclid and
Archimedes, and could be kept at medicine no more. At 26 was appointed
Lecturer in Mathematics a
