of systematic botany. As to the form which we predicate of the vegetable world, 
or as to how far we understand the latter in so doing, I shall speak in detail 
later on. But, for the present and for the sake of convenience, I shall’merely give 
Forms of plants are originally numerous ; but in their 
this general answer : 
real existence, they are all the same. They present different phenomena according 
to the different circumstances conditioned from eternity to eternity by the causal 
nexus. Their forms in different phenomena are naturally in inter-relation like 
the meshes of a net”; but not in a serial relation like the branches of a tree. 
We have spoken just now of real existence and phenomena separately ; 
but real meanings of both terms are comprehensible only in their perfect unity 
in oneness. In other words, species are quite similar in their basic cha- 
racters ; but they are different in their particular manifestations. Here again, 
as in the above case, both basic characters and particular manifestations are 
to be understood only in their unity — not separately. 
3. SPECIES. 
We have spoken above of species but vaguely. Now, what is meant 
exactly by species. It must, of course, that the definition of species differs. 
according to one’s idea of what constitutes a species. My opinion is that a 
Species is an individual presenting a certain manifestation in a certain gene- 
themselves. As to the principal aim of systematic botany, it could not be more eloquently ex- 
plained than by 1 sentence on the title page of the thesaurus. It runs:— “It is impossible that 
we should thoroughly understand the nature of the signs, unless we first properly consider and 
arrange the things signified” The more I look at Rogrr’s work, the more I become astonished 
at the curious coincidence in the construction of the thesaurus and that of my present paper. 
His dictionary consists of four parts, namely :—1, introduction explaining the theory and principle: 
upon which his classification is grounded; 2, plan of classification and synopsis of categories; 
3, the thesaurus itself; 4, index. His introduction somewhat corresponds to the theoretical part of 
the present paper; his plan and synopsis exactly answer to the static classification taken in my 
paper as a framework or nucleus for the construction of my scheme; his thesaurus accords with 
my dynamic system anil its explanation; and finally his index is constructed exactly like my 
index. This agreement shows, I sincerely believe, that things like words or plants are all under 
the rule of the same universal lav.—Cf, Rocer, P. M.—Thesaurus of English words and phrases,.
