As regards Coeeespondence, we still are well supplied, but we 

 must again threaten, that if our friends will send us such long letters, 

 we shall be obliged to make an abstract for insertion, instead of 

 printing them in extenso. 



Our Aetists, and Peintees, and Publishees continue to do their 

 best ; and if only more Subscribers will lend us their aid, we are 

 sure to succeed in the future.

 are earnestly requested to send in their names and subscriptions to 

 Messrs. Triibner & Co., 60, Paternoster Eow, London, E.G.

 through this method of procuring it, the Publishers will always be 



happy to send it direct per post.
