Received : A Classified List of British Mosses, by George Dixon. 



We greatly regret that our Subscribers should not have received the April Naturalist 

 at the proper period. The following explanation will, we trust, exonerate us from blame 

 in the matter. The Naturalist, being printed hi the country, has to be sent to London 

 some days before the end of the month. The parcel containing the copies was sent off by 

 Railway on the 24th of March, but was mislaid by the Railway people until the 6th of 

 April, when it was found in the station at which it had been delivered on the 24th of Marcli ; 

 it was of course at once forwarded to London. 



We have taken steps to sue the Company for damages, which we have no doubt we 

 shall obtain. 



We trust our friends will aid us in endeavouring to prevent this unfortunate occurrence 

 from permanently mjuring the sale of the Magazine.
