294 Analyses of Books. [April, 



of individuals, we presume that our readers will be gratified 

 by receiving from time to time some account of their proceedings. 

 We shall, therefore, transcribe the titles of the papers, and give 

 a few observations on those that we think the most interesting. 



Description of the different Plants grown in the Gardens under 

 the Denomination of Whiter Greens, with an Account of their Qua- 

 lities, of the Seasons in which they are to be used, and of their 

 Cultivation. By Mr. W. Morgan. — The different kinds of green* 

 which Mr. Morgan enumerates, are the green savoy, the dwarf 

 savoy, the yellow savoy, the Brussels sprouts, the green borecole 

 or Scotch kale, the purple borecole, and some other less im- 

 portant varieties. We regret that the author has not given the 

 scientific names of these plants, that they might have been 

 clearly identified, which cannot be done with any certainty by a 

 mere description, such as we have in this paper. 



On the Application of Steam and its salutary Effects on forcing, 

 particularly as applied to the Pine Apple. By Mr. James Brown; 

 to this is added some Observations on Mr. Brown's Plan, and 

 Suggestions for its Improvement. By Thomas A. Knight, Esq. — « 

 The advantages which steam is said to possess over heat applied 

 in the usual method is, that the degree may be more nicely 

 regulated, and that the moisture which may be introduced in 

 this way into the house is frequently very salutary to the plants. 

 The paper is accompanied by a plate, in which the constniction 

 of the apparatus is clearly described. 



Observations on the Verdelho Grape. By Thomas A. Knight, 

 Esq. consisting of a recommendation of this variety of grape, as 

 an object of general cultivation ; an account of the variety is 

 contained in the Horticultural Transactions for 1814. 



Account of a Method practised by Mr. James Mean, Gardener 

 to Sir Ab. Hume, Bart, at Wormleybury, Hertfordshire, for 

 ripening Grapes by Means of Dung-Heat under a common hot- 

 bed Frame. Drawn up by the late George Anderson, Esq. 



Account of the Method of growing Mushrooms in Houses. By 

 Isaac Oldaker. — This plan, which is said to have been tried for 

 some years with complete success, consists in forming a building 

 with flues, and with different heights, or tiers of beds, like 

 shelves, in which the compost is deposited, with a walk in the 

 centre. For the minute particulars of the plan we must refer our 

 readers to the engraving, which accompanies the paper. We 

 have accurate directions added for preparing the soil and furnish- 

 ing it with the spawn. 



Description of a Method of numbering Marks, or Tallies, for 

 Plants. By Alex. Seton, Esq. — This is a simple and ingenious 

 method of applying to the tallies a system of notches, made in 

 different directions, and which are supposed to correspond to 

 the Arabic numerals, and thus to supersede the marking of 

 them by ink, or paint, which is very liable to be effaced. 



Suggestions for the Improvement of Sir George Stuart Mack-
