_ Many of those mentioned are certainly the greatest authorities 
in their respective studies. To refer to all their work would be 
an enormous undertaking. I may however be pardoned if I 
single out one to whose help and encouragement I owe much ; I 
refer to the late Dr. Clifton Sorby. He was, unquestionably, a 
giant in the scientific world, and the full importance of his 
attainments will never be fully realized. Had Yorkshire done 
little else than produce a Dr. Sorby, it would have good cause to 
be proud of its contribution to science. 
I can speak with perhaps greater pride of the work of York- 
shire’s scientific worthies, as Iam not prejudiced ; for, though I 
have spent all the time I can remember in the county, Iam not a 
native ; a brief visit to the neighbouring county of Lincoln at a 
rather critical period of my little career, causing me to be, in the 
eyes of the law, a native of that shire. 
Yorkshire’s contribution to science. In connection with the 
bibliographical work already referred to, the collecting mania 
somehow seemed to take a hold on me and I began, by begging, 
buying, borrowing, or by other ways, to accumulate sets of vari- 
ous scientific publications ; those referring to Yorkshire alone, 
which I have obtained, occupy an enormous quantity of book 
shelving. 
While, I regret to say, I have not yet been able to secure 
complete sets of all the scientific publications issued in the county ; 
I have, through the help of friends, carefully examined practically 
everything that I have been able to trace. As, in many cases, 
it is apparent that only one set is known (even of our own journal, 
The Naturalist, there appears to be only one really complete 
set in existence !), it seems desirable to place on record, before it 
is too late, particulars of the work of our Yorkshire societies 
and their publications, with some indications of the contents, so 
that future workers will be able to know what has previously 
been done, and thus get a good foundation for their researches. 
I should like to lay particular stress on the necessity for stud- 
ents to become familiar with the records of their predecessors in 
the same field, as over and over again it is found that alleged 
“new records’ have been known years previously by earlier 
naturalists. Not long ago a friend of mine sent me a lengthy 
account of an early and important record, which had obviously 
been transcribed at great pains and printed at some cost; and 
he was quite unaware that every word had been issued a century 
previously in the publication of our oldest London Society ! 
Quite apart from the quantity of publications now being 
issued, there is an enormous number of magazines and journals
