GREENHOUSES. 



To tMs aiTangement it may be supposed that we should have added 

 The AauARiuM, but as most exotic aquatics are intra-tropical, we shall 

 notice them when we come to treat on the subject of plant stoves. 



In the progress of this work it will be seen that arrangements have been 

 made, wliich we trust vrill meet the views of most of our readers, by offering 

 selections of such plants as may be admitted into each of these divisions, 

 ^nthout infringing the rules we have laid down. And as this is the first 

 time that such an arrangement has been recommended upon so general a 

 prmciple, we shall rejoice to see it reduced to practice by some of our 

 enterprising and inteUigent readers.
