Some of the earlier illustrations from the “ Zoological Keepsake ” seem very 
quaint now-a-days ; but we surmise that many of those reproduced from the 
Illustrated London News were the work of Mr. Harrison Weir, whose death we 
have had so lately to deplore. This edition of a most interesting work, upon 
which we congratulate all concerned, is limited to a thousand copies. When 
Mr. Scherren comes to re-issue it, we would suggest that some portraits and 
biographical particulars of the founders of the Society and other eminent men 
who have been associated with its work, would add considerably to the interest 
of his story.
