system of botany. The herbaceous plants will be much more 

 sheltered by the trees ; and all the front trees, to exemplify the 

 orders, will have a greater space to extend their foliage than 

 they generally have when arranged at equal distances from the 

 walks ; and the breaking of the regular curved line, I am per- 

 suaded, will add much to the picturesque effect of the garden, 

 from the terrace and other places of view. I have likewise 

 endeavoured to combine the pictorial with the scientific arrange- 

 ment; for all herbaceous plants whose developement is quinary 

 are arranged in groups of five beds ; if quaternary, in groups 

 of four beds; if ternary, in groups of three beds; which 

 arrangement may be well illustrated in the laying out of 

 gardens. 



In the zoological arrangement, I have merely fixed the situa- 

 tions of some of the houses for animals, birds, &c. ; for, not 

 knowing the collection the Society may procure, I thought it 

 of no use giving any elevations. I have fixed the sites for many 

 of the houses in the arboretum, chiefly where the orders contain 

 climbing plants, which houses, when partially overgrown, would 

 have a more natural and picturesque effect, than if they were 

 placed on the open lawn; and I would, as much as possible, 

 endeavour to bring the geographical range of plants and animals 

 together, wherever it could be effected. If your collection should, 

 in a few years, become extensive, a more scientific arrangement 

 of the orders might be adopted. Movable cages for birds and 

 small animals, poles for monkeys, &c., might be placed on the 

 lawn in the summer season. 



The preceding remarks being much longer than I intended, 

 I will not trouble you further than to refer you to a paragraph 

 in the Leeds Mercury for Jan. 1833, in which some of my views 

 on botanic gardens were stated, but shall now proceed to an 

 explanation of the plans.
