thirty years, it is evident that when Jupiter has made five, 

 Saturn will have made two revolutions; for twice thirty 

 is sixty, and so likewise is twelve times five; so that their 

 revolutions will be conjoined in sixty years. Souls, there- 

 fore, are punished for such-like periods. But the seven plane- 

 tary spheres conjoin their revolutions with the inerratic sphere, 

 through many myriads of years ; and this is the period which 

 Plato calls rov aet xpovov, for ever. See the Introduction 

 to the volume of my Aristotle, which contains a translation 

 of Aristotle's treatise on the Soul, &c. &c.
