a complete system by means of which plants could be grouped, 
and whose conclusions may be verified and have been verified by 
examination of the materials on which his results were based. 
To the statements that “few or any of the names are likely to 
be older than the Latin or Greek languages in whose vocabularies 
they are found,” I must therefore take decided exception. 
A point of departure such as I have indicated, being then in 
my opinion a necessity of the case, it will be seen that if my views 
are to be maintained, this must be found at the writings of either 
Tournefort or Linnzus, the systems they established being com- 
plete in the light of the information they possessed, and their 
genera practically every one recognizable from their books or 
herbaria, and even should the latter be destroyed, the knowledge 
of their genera is so widely diffused that there would never be 
any uncertainty about them. Tournefort’s system is a generation 
older than that of Linnzeus, and if there were no other circum- 
stances to be considered, would have overwhelming claim to the 
distinction. But thereisa very grave difficulty in adopting it, and 
one which I believe will ever render it unavailable. It is this: It 
is of the very highest degree of importance that the two sciences of 
botany and zoology should go hand in hand, and the zoologists 
can never go back to Tournefort, because he established no ani- 
_ mal genera. The versatile Linnzeus, however, brought together 
all Natural History in his Systema Nature. He was familiar 
with plants, animals and minerals. I doubt if it can be satisfac- 
torily maintained that he was more botanist than zoologist. He 
must have known the whole range of nature better than any 
other man of whom we have any record. The collections which 
he brought together were actually immense for his time, and his 
library was of the richest character. Besides all this, he certainly 
established the binomial system of nomenclature, and its general 
acceptance dates from his time, no matter what authors may have 
used it before. Tournefort did not use it at all, so we cannot go 
to him for species, another consideration which with me is a 
strong argument against going to him for genera. And so, as I 
said in my review of my friend’s work, it seems better to me not 
to go back of Linnzeus,
