_We are again compelled by the number and value of the communications, which have reached us, to present our Readers with an extra Eight Pages. We trust, therefore, we shall be excused if, with reference to what we stated a fortnight since, on the subject of making this enlargement_ permanent _instead of_ occasional, _we quote from a valued correspondent the mode he has kindly adopted with the view of promoting that increase of our circulation, upon which such_ permanent _enlargement of our paper must depend._ NOCAB _writes thus:--"Whenever I find an article in any Number which I know to be peculiarly congenial to the taste of any of my literary or scientific friends, I forward them a copy. A letter of thanks and an_ intention of future subscription _has almost invariably been the result." We are sure that this hint will not be lost upon our friends._ P. _will find his communication on_ Averia _inserted in_ No. 69. p. 157. S. H. H. _Received, and will be taken care of._ COMETS AND ECLIPSES. _We are requested by our valued correspondent_ C. _to say that his Reply_, p. 253., _should have been headed_ Eclipses, _and was intended to refer to the list of_ Eclipses (_not Comets_) _in the work to which he refers. He was probably led into this slip of the pen by the manner in which_ S. P. O. R. _had, in_ No. 73. p. 223. _mixed up Comets and Eclipses in the same Query._ JARLTZBERG _has our best thanks. We receive his friendly suggestions in the spirit in which they are offered; and will, as far as practicable, attend to them. We trust he will receive in the same spirit our explanation, that the delay in inserting his communications arises chiefly from the difficulty in deciphering them. Our correspondents little know how greatly editorial labours are increased by this apparently trifling cause._ E. T. C. _Our correspondent will find, on referring to our First Vol._, p. 445., _that the so-called French original of_ "Not a drum was heard," _is only a clever literary hoax from the pen of Father Prout, which first appeared in_ Bentley's Miscellany. J. B. C. _A proof of the Sovereign of 1820; and if in very good condition, would perhaps sell for Two or Three Pounds._ LLEWELLYN. _Will this correspondent favour us with his address, that we may forward a communication which we have received for him?_ ACHE _is requested to say how a communication may reach him._ F. R. R. _We have a further Query for this correspondent on the subject of Sir Andrew Chadwick, if he will favour us with his address._
