they are one and the same plant. The difficulty that exists in ascertaininj^ 

 distinctly the varieties of the genus Citrus is very great. The same plants 

 sent to the Italian warehouses from different countries bearing different 

 names. Many varieties have been raised from seed even in this country', of 

 which the Kitley Shaddock (Vol. I. p. 265.) is one. It is a sweet fruit, and 

 well worthy of culture. 



I have not yet had the good fortune to procure a plant of the Grape 

 Fruit, or Cluster Pompoleon ; I have met with small plants of it in some 

 few private collections, but have never seen it in bearing. 



Your correspondent will find it difficult, if possible, to procure by pur- 

 chase plants of the Forbidden Fruit, Pompoleon, Sweet Lemon, Sweet Lime, 

 and Kitley Shaddock. If scions of them, in February next, will be accept- 

 able to him, I shall have great pleasure in presenting them to him ; as a 

 tribute of respect, I must be allowed to feel for a brother cultivator of this 

 beautiful tribe of plants. He will, therefore, have the goodness to let me 

 know, before that time arrives, in what manner he would wish to have them 

 sent to him. 



May I take the liberty to ask your correspondent, why he has not sent 

 specimens of his Sour Shaddock, of the abundance of the fruit of which he 

 so honourably boasts, to the exhibitions of the Horticultural Society, which, 

 as he probably knows, are held at their house in Regent Street twice every 

 month ? Cultivators of rare fruits, at a distance from London, are impro- 

 perly negligent on this point ; for, however sensible of the abuses and errors 

 of this Society I may be, I would yet have that attention paid to them that 

 their good deeds in the way of promoting the science of gardening deserves. 

 They, or rather we (for I am a member of that overgrown and fete-giving 

 establishment), undoubtedly have great claims upon our assistance. 



Does your correspondent know that a splendid work on the orange tribe 

 has been published within the last few years, by M. A. Risso, of Nice, enti- 

 tled Histoire Naturelle des Oranges, folio ? Yours, &c. &c. — An Amateur,

Seedling Myrtles.- — What is the quickest way of flowering seedlin"' 

 myrtles, of which I have got about thirty, eight of which are two years old, 

 from seeds of the M. latifolia ; the rest one year old, from the Devonshire 

 myn\e?—W.G.T. 



Gold and Silver Fish. — I should feel obliged if some one of your corre- 

 spondents would favour me with some account of gold and silver fish, their 

 time of spawning, breeding, &c. ; where they may be purchased to stock a 

 basin, and the price. As I understand from J. H. (p. 191.), that they breed 

 fastest in warm water, I should wish to know how this may be given them ; 

 also the name of any author who has written on the subject of keeping and 

 breeding them ? — A Constant Reader. June 26. 1828. 



Lamp for a Green-house (III. p. 565.) — In pages 42 — 55. of Dr. hndev- 

 %ox\'s Description of a Patent Hot-house, 12mo, 1803, is a proposal for 

 heating a green-house by the argand or patent lamp. The method is by a 

 tin tube conveying the cold air from the exterior to the air-tube of the 

 lamp, and, when the lamp is put out, the external air-tube is to be stopped. 

 He says that in a small house, 12 ft. long, a lamp raised the thermometer 

 five degrees in a quarter of an hour. The question has before been put in 

 your Magazine, but, not being answered, I have taken the liberty of saying 

 where the intelligence can be got. — Superficial. Brixton Villa, January. 



The Spot on Cucumbers, in answer to F. (p. 189.) — I beg to say that it 

 is not caused by any insect, but entirely a consequence of cold, and too 

 much moisture. Sufficient bottom-heat and dry warm air always prevent 

 this disease ; and, even after it appears, if the heat be renewed by linings, 

 &c., its progress will be arrested. — J. D. Paries. Arran Lodge, Bognor, 

 Sussex, June 12. 1828.
