and flowered at his seat, Bury Hill, Surrey, which has lately been sent us by 

 Mr. Cameron, the gardener at Bury- Hill, we find that some of the finest of 

 them, such as Quisqualis Indica, (Enothera speciosa, &c. were previously 

 flowered there. 



25. Observations on a Disease to 'which Grapes are liable, and on the 

 Means of preventing it. By Mr. Daniel Judd, F.H.S. Read 

 November 16. 1824. 



After the berries are formed upon a bunch of grapes, they 

 advance pretty rapidly in size until the period when the seeds 

 are forming, when for a time their increase seems suspended. 

 Immediately after this, it sometimes happens that the foot- 

 stalks suddenly turn brown and shrink, and the berries ceasing 

 to increase in size, shrivel, acquire an unpleasant taste, and 

 ultimately fall off. By many gardeners this disease is attri- 

 buted to the badness of the border on which the vines are 

 "planted, but it will be found that it arises from an over-moist 

 atmosphere. 



" At the formation of the seeds, the skins of the berries, as well as of the 

 foot stalks, are remarkably tender, and consequently easily affected by the 

 surrounding atmosphere. If fresh air is not given early in the morning, 

 before the internal air becomes heated, a vapour rises in the house, which is 

 perceptible by its condensing on the glass and walls, and on any iron-work 

 that may be in the house. If under these circumstances the bunches of 

 fruit are carefully examined, the moisture will be found plentifully collected 

 on the berries, and more particularly on the foot-stalks. This is the de- 

 structive material, for as the temperature of the house is increased, an effect 

 equal to scalding is produced on the cuticle of the berries, and hence the 

 diseased appearance which they assume, and should the sun break suddenly 

 out, the destruction becomes complete. 



" To prevent this, one or two of the top sashes should be drawn down a 

 little, early in the morning ; and if the day opens out bright and sunny, the 

 rest of them may also be drawn down. Unless the day be very warm, the 

 front lights should not be opened ; for a current of air is produced by this, 

 which in cold weather is very liable to produce a spotting upon the berries, 

 a disease scarcely less injurious than the scalding. This, however, does not 

 prevent the berries from colouring ; but if the spots become large, the berries 

 take an irregular shape, and cease to improve in size. The first appearance 

 of this disorder is a number of very minute brown spots, which penetrate 

 quite through the skin, sometimes affecting some of the berries only, some- 

 times the whole bunch." 



26. Description of the different Varieties of Parsneps, cultivated in 

 the Garden of the Horticultural Society of London. By Mr. An- 

 drew Mathews, A.L.S. Read December 6. 1825. 



These are; 1. the common; 2. the Guernsey, a variety of 

 the common ; 3. the hollow-crowned parsnep, with shorter and 

 fewer leaves than the common, and oblong roots more swollen 

 at the top ; 4. the turnip rooted, with few leaves, early and the 

 best flavoured. The merits of the three first are nearly 

 equal.
