comet of 1811, relative to the changes of distance from the
Sun, and the modifications resulting thence, Herschel put it
beyond doubt that these modifications have something individual
in them,--something relative to a special state of the nebulous

an enormous effect, on another the modifications are

We have reproduced these observations by a distinguished French
astronomer, in order to show the reader what was the nature, and how

and comprehensive a manner he conducted his survey of the celestial
phenomena. We now return to our brief narrative of his life.
