The _Instauratio_, as he planned the work, "is to be divided," says Mr. Ellis, "into six portions, of which the _first_ is to contain a general survey of the present state of knowledge. In the _second_, men are to be taught how to use their understanding aright in the investigation of nature. In the _third_, all the phenomena of the universe are to be stored up as in a treasure-house, as the materials on which the new method is to be employed. In the _fourth_, examples are to be given of its operation and of the results to which it leads. The _fifth_ is to contain what Bacon had accomplished in natural philosophy _without_ the aid of his own method, _ex eodem intellectûs usu quem alii in inquirendo et inveniendo adhibere consueverunt_. It is therefore less important than the rest, and Bacon declares that he will not bind himself to the conclusions which it contains. Moreover, its value will altogether cease when the _sixth_ part can be completed, wherein will be set forth the new philosophy--the results of the application of the new method to all the phenomena of the universe. But to complete this, the last part of the _Instauratio_, Bacon does not hope; he speaks of it as a thing, _et supra vires et ultra spes nostras collocata_."--_Works_, i. 71. The _Novum Organum_, itself imperfect, was the crown of all that he lived to do. It was followed (1622) by the publication, intended to be periodical, of materials for the new philosophy to work upon, particular sections and classes of observations on phenomena--the _History of the Winds_, the _History of Life and Death_. Others were partly prepared but not published by him. And finally, in 1623, he brought out in Latin a greatly enlarged recasting of the _Advancement_; the nine books of the "_De Augmentis_." But the great scheme was not completed; portions were left more or less finished. Much that he purposed was left undone, and could not have been yet done at that time.
