* * * * * Several books have reached us for notice in this Journal; but unless they are sent earlier in the Quarter, we cannot insure attention to them. * * * * * We have been favoured with communications from Mr. Swainson, Dr. Littledale, Mr. Rose, and E. Z., which we are obliged to postpone. * * * * * A letter from a “Member of the Zoological Society,” reached us too late for the purpose it was intended to answer. We fear we shall not agree with him in opinion, but perhaps his _second communication_ may clear up the difference. * * * * * We presume that “A Mechanic” will find the information he requires in Mr. Farey’s account of the Steam Engine. * * * * * “An old Subscriber” is much in error—the _proceedings_ he alludes to are copiously given in contemporary monthly publications; if therefore we followed his advice, our information would be stale. The motives he alludes to are out of the question. * * * * * We cannot give “A Vapourer” any authentic information respecting the Steam Carriage, nor do we hear that the Gas Engine has advanced.
