 manner. Likenesses and differences are by this mode of arrangement ren- 

 dered instantly and palpably obvions; and it was anxiety to attain this 

 point which led the able author of Dcndrologia Biitdiiuica to ado})! the 

 peculiar and remotely similar mode of describing in detail which that 

 really meritorious work exhibits. In conclusion, we have only to say, we 

 have had the jileasure of cultivating a hybrid, very similar to that which 

 forms the subject of Professor Ilenslow's pamphlet, and that that hybrid, 

 like his, was altogether barren of seeds. — ./. 1).

We have read through this pamphlet, and shall offer no analysis of it ; 

 for this, besides occupying more space than we can spare, would be only 

 acceptable to cultivators of this charming genus, ant! every one of these 

 should procure and possess the work. It contains no specious theorising, 

 but is a straightforward narrative of the results of the writer's long ami 

 extensive practical experience in his remarkably successful cultivation of 

 this most charming genus. 



]NL\ M'Nab deserves the hearty thanks of all who are interested in the 

 promotion of floriculture, for having shown so clearly by what simple 

 means the Cape heaths can be grown healthily ami vigorously, and there- 

 fore satisfactorily. A feeling of misery is ever associated by a sight of sickly 

 exotics; antl one tuft of native heather, luxuriating in health and beauty, 

 is a far more pleasing object than a house full of such; but how delightful 

 must be the sight of Mr, M'Nab's collection when the majority of species 

 is in bloom ! They seem unaftiictcd by sickness and debility. " There 

 are," says he, "in the Botanic (Jarden, at lulinbin-gh, heaths 8 ft. high, in 

 tubs .'J ft. over; ami the plants are both liiishy in proj)ortit)n to their height, 

 and in great vigour; and these, when in flower, are covered with blossoms 

 from the edge of the tubs to the top of the plants. These are, however, 

 the fieer-grovving kinds, such as A'rica Ewerw//«, BonplanihV/<;«, wbietina, 

 vestita coccinea, grandiflora, <!vc." The book is indeed cheap. — ./. I). 



(Since the |)receding notice was written, a valued corresjjondcnt has sup- 

 plied the following remarks. They corroborate oiu" own, ami also take 

 additional views : — 



It may justly be said of Mr. M'Nab, " that he is a man of that stamp 

 that would not write on any department of gardening, unless he coidd 

 show the good effects of it in his own practice;" a compliment which he 

 is pleased to pay (p. 7.) to Mr. Waltir Henderson, gardener at Woodhall. 

 To the justice of this remark the beautil'ul heaths at the Uoyal Botanic 

 (Janlens of Edinl)urgh bear ample testimony. From some su|)i)osed dif- 

 ficulty in the |)roper treatment of heatlis, that beautiful family of plants 

 has certainly not met with the general encouragement which their .splen- 

 doiu", and simple and cheap mode ol" cultm-e, seem to warrant. The 

 excellent little treatise now belore us will, we doubt not, soon prove the 

 ineanii of exciting a taste for, and of extending the culture of, the heaths
