side ; and the house, as we think, will be more easily overheated in bright 

 sunshine, and cooled when the wind is in the north. As far as we have been 

 able to observe ourselves, and to hear the result of the experience of garden- 

 ers, a house with glass on both sides should always stand south and north, 

 except in the three following cases : 1. when it is separated lengthwise by 

 a wall or other division along the centre, in which case the north side may be 

 kept at a different temperature and degree of atmospheric moisture from the 

 south side ; as in the case of Messrs. Loddiges's camellia-house ; 2. when the 

 house is of massive architecture, in which case, the effect both of light and of 

 cold winds is moderated by the thickness of the columns or pillars of the sides, 

 and the rafters of the roof; and 3. when orchideous or other plants requiring 

 constant shade on the south side are to be grown. We admit, however, the 

 force of the following passage in Mr. Bentham's letter in answer to our 

 objections : — " As to direction, it appears to me that the cold winds, which 

 are seldom due north, are as likely to strike on an east as on a north side, and 

 the inconvenience arising from the unequal distribution of the sun's rays 

 must be much less in a house with glass on all sides, than in any other. 

 Indeed I should think that the disadvantages you mention would be much 

 less felt in an east and west house of this description, than in a north and 

 south one ; whilst there are greater facilities in regulating the protection from 

 sun on the one side and from cold on the other, and in the advantageous 

 arrangements of the plants within side." 



We reserve some remarks made by different correspondents on the expense 

 of this conservatory, and the risk which they allege is being incurred of 

 plunging the Society as deeply in debt as before, till a future occasion ; sin- 

 cerely hoping that matters are not so bad as some assert them to be. We 

 have now done what we conceive to be our duty ; we trust without giving 

 personal offence to any one connected with the gardens, and with the chance 

 of doing some good to a certain portion of our readers.
