to No. 2, above). 
They form a library of information in regard to the 
principles of nomenclature for careful reference at all times. 
The main decisions of the Vienna Congress were soon 
made known by means of botanical and other scientific 
journals, and I give references to some’ of the excellent, 
though necessarily brief accounts which appeared at the 
time. 
But, although these accounts are based on the reports 
of eminent botanists, they are all unofficial, and I have the 
honour to bring under your notice the official document’ 
which I received early last month, and which is, probably, 
the only copy in New South Wales at present. 
It is an epoch-making document, and every Australian 
botanist will require to make himself acquainted with its 
provisions. He can no more ignore the decisions than can 
a citizen ignore the laws of his country. This document 
isan extract froma larger volume* which contains a report 
of the debates which led to the adoption of these Interna- 
tional rules of botanical nomenclature.
