766 Rev. G. Wheeler on the Dates of the 
Street, and C. F. Prorth, of 88, Fetter Lane. The former 
of these firms informs me that all the books which might 
have given information were destroyed by a fire in 1880, 
whilst the latter, whose books up to 1850 have also been 
destroyed, have kindly provided me with almost all dates 
of delivery to the Society between 1850 and 1867, and 
also with a few subsequent to that year. These, I believe, 
may be regarded as exact and reliable, though it is possible 
that in some cases copies may not actually have been 
obtainable till the following day. 
Messrs. West, Newman & Co., who printed the Trans- 
actions from 1880-1893, have furnished me with dates for 
those years, which, however, are not to be relied on for 
fixing dates of publication, as the following extract from 
their letter shows: ‘‘We do not guarantee these dates at 
all as the exact ones of issue. We have taken them from 
our Ledger books—the only possible method at this 
distance of time. To look up deliveries would be a ques- 
tion of an immense time, even if we have all our delivery 
books to refer to, which is unlikely.” <A few of the dates 
given are manifestly incorrect, as they are later than those 
of the Postage Book of the Society, but since they are, as 
a rule, earlier than any others obtainable, I have given the 
entire list, though I have not ventured to use them as the 
dates of publication. 
The printing firm employed from 1894 to 1897 I have 
been unable to trace. .
