ADDENDA.
Since the Catalogue was printed, the members of the Committee entrusted with its publication have had the opportunity of consulting The Halifax Philatelist for the current year (1889), the numbers of which had not previously been seen by them.
The May number contains a copy of a recently-published Canadian postal notice, referring to certain alterations in the rates, &c.; and in the numbers for January and February Mr. Donald A. King has two further papers upon the stamps of Nova Scotia; while the April number contains a letter from a correspondent upon the bisected stamp of New Brunswick. The Committee consider it advisable to reproduce here all the four articles mentioned, feeling sure their contents will be of interest to philatelists, and help to add further to the completeness of the postal history of each of the provinces.
