THE ICHTH'iOSAUR. 



This fossil reveals to us some of the life-history of the giant lizard-fish. We learn that the young Ichthyosaur was not 

 hatched out of an egg, but was born fully developed. 



and become toothless, like so many of the whales These strange water-monsters died out, as far 

 as we know, before the beginning of the Tertiary Epoch and before they were displaced in the waters 

 by the mammalian whales. 



THE PLANET JUPITER 



BY REV. T. E. R. PHILLIPS, F.R.A.S. 



THOtJGH surpassed by \'enus in lustre, by Saturn in beauty, and by Mars in general interest, Jupiter 

 easily holds the palm amongst all the planets in point of size. In fact, he is larger than all of them 

 put together and exceeds our own little Earth more than thirteen hundred times. It is true we 

 have every reason to believe that his globe is greatly expanded by heat, and that were he in the 

 same physical state as the smaller planets his bulk would be much less, but all the same the 

 revolutions of his satellites tell us that he must be more than three hundred times as massive as 

 our own globe. This giant orb revolves round the sun at more than five times the distance of the 

 Earth, and requires nearly twelve of our years to complete one journey. 



If we look at Jupiter through a good telescope we see at once that he is not a true sphere, but 

 flattened like the Earth at the poles, only to a much greater extent. This is because he is spinning 

 round on his axis very fast indeed, and the same circumstance causes the dense vapours surrounding 

 him to assume the form of paraUel streaks and bands. These markings are by no means uniform, 

 but irregular and spotted, as will be seen from the accompanying drawings.
