W. DENISON ROEBUCK. F.L.S. : PRESIDENTIAL ADDRESS. 11 
Under this editorship it assumed a more scientific character, 
and became much more strictly local in its scope. This series, 
published from August, 1875, to July, 1884, ran to nine volumes. 
There was no break in the time when the seventh series 
replaced its predecessors in August, 1884, but the place of 
printing and publication was transferred to Leeds. 
Mr. W. Eagle Clarke and myself became editors, a post 
from which the former retired in 1888, leaving me in sole charge 
till 1892, when Mr. Edgar R. Waite became my colleague for 
one year. My own editorship came to an end at the close of 
1902, and the Journal is now in the capable hands of Mr. T. 
Sheppard and Mr. T. W. Woodhead. 
During the whole of its existence The Naturalist " has 
been a valuable medium for recording the observations and 
discoveries of Yorkshire naturalists, and forms a storehouse of 
information, which no Yorkshire investigator can safely ignore. 
Our Transactions, too, take their stand along with our 
magazine, and have especially afforded the means of publishing 
lists and monographs too bulky for a magazine. 
One volume consists of the Flora of West Yorkshire," by 
F. Arnold Lees, the most complete work of the kind in existence. 
We have also published nearly the whole of the second edition 
of Baker's valuable work on North Yorkshire, which we hope 
may soon be completed. Another volume is devoted to the 
" Alga-Flora of Yorkshire," by W. West and his son G. S. West, 
and it will not be long before the companion work the ** Fungus- 
Flora of Yorkshire," by Geo. Massee and Charles Crossland, 
follows it. 
The List of Yorkshire Lepidoptera, " by Mr. G. T. 
Porritt, of which we have just published a second edition with 
supplement, is also one of the most complete works of which any 
county can boast. 
Of works which are appearing in our transactions, but are 
yet incomplete, we may cite Messrs. Taylor and Nelson's *' List 
of Land and Freshwater Mollusca of Yorkshire," which is written 
on a most admirable and exhaustive plan; the " Birds of York- 
shire," which Mr. Eagle Clarke's early removal to another part 
of the kingdom prevented being finished; the "Yorkshire 
Carboniferous Flora," by Mr. Robert Kidston, which is complete 
so far as known investigations go; and the Rev. W. C. Hey's 
" List of Yorkshire Coleoptera," as all being works of great 
value. 
My review ought to include a sketch of the progress of 
research in each of the various departments of study included in 
our scope, but the task is a formidable one, and the exigencies 
of time and space prevent me. Suffice it to say, that in nearly 
every department of the natural sciences, the Union has been 
actively concerned throughout the past forty years, and the 
number of really able Yorkshire investigators has been remark-
