MELVILL : THE PRINCIPLES OF NOMENCLATURE. 449 
ture, had meanwhile finished their labours, and submitted to 
the approval of the Association, to use their own words, a 
“Series of propositions for rendering the nomenclature uni- 
form and permanent.” The committee originally consisted of 
the following eight persons: Prof. Henslow, Rev. Leonard 
Jenyns, Mr. W. Ogilby, Dr. Richardson, Messrs. Charles Dar- 
win, J. Phillips, H: E. Strickland (reporter), and Mr. J. O. 
Westwood, to which names were subsequently added the 
following five: Messrs. W. J. Broderip, W. E. Shuckard, G. R. 
Waterhouse, W. Yarrell, and Professor R. Owen. It was accord- 
ingly an exceedingly representative list. 
The rules will be found in the Report of the Twelfth 
Meeting of the British Association (1842), pp. 105121. They 
were revised, as will be presently explained, in 1864, and at the 
request of the General Committee of the British Association at 
the Plymouth Meeting in 1878, they were again reprinted and 
edited by Dr. Philip Lutley Sclater, F.R.S. 
I think it will not be amiss here to give a short outline of 
what is known as the ‘Stricklandian Code,’ especially as with 
the few emendations and additions, shortly to be summarised, 
it is still in vogue, and will, we believe, always remain in 
force, at all events in this country. And since I have just 
alluded to the scene of the labours of this committee, it is 
especially interesting for us to be, fifty-four years later, 
gathered together in the same city to examine and taste for 
ourselves the splendid fruit of the seed sown here in 1842.

vernacular, nomenclature. 
Priority to be considered the only possible basis, as well as 
the only just and equitable starting-point, and the date of the 
commencement of Binomial Nomenclature to be that of the 
XII Edition of the “ Systema nature” of Linneeus, 1767.
