]May 4, 
The work has, as is often the case, grown much beyond the size 
and cost at first anticipated, and the receipts from sales will fall 
far short of cost. Its publication has, moreover, put almost an 
entire stop to the regular “ Proceedings,” and only four signatures 
towards the last part of Vol. XX have been issued since last May, 
leaving the Proceedings over a year behind time. This delay is

sums.
