a comjiound corymb of small white flowers resembling those of 

 the common scurvy grass. It has not produced any fruit. 



It is a hardy perennial, growing freely in any good rich 

 garden soil, and well suited for planting on rockwork. It flowers 

 in July and August, and is easily increased by dividing the old 

 plants in autumn or spring, or by seeds : the plants raised from 

 seed will not flower before the second season. 



It must be considered a good hardy plant for rockwork, and 

 rather showy, as it flowers abundantly. I

MEMORANDA. 



Destruction of Insects. 



Shore's Remedij. — Mr. E. C. Shore,* who was recommended to the Society 

 as a person in possession of the means of destroying insects, was permitted 

 to experiment on various plants in order to test the efficacy of the sub- 

 stances which he employed. Every facility was afforded him ; but he found 

 that success did not correspond with his expectations, for the plants were 

 killed or greatly injured in many instances, although the insects were not. 

 The red spider on peach trees was killed, but the shoot died next day. The 

 turnip flea was not killed by a powder sprinkled over the plants. — Robert 

 Thojipson. 



In the Hothouse Department eight common plants of various sorts were 

 selected. The substance was used in a pounded state, and the plants were 

 dusted over with it; also dissolved in water and applied' with a syringe. 

 This was done by Mr. Shore in my presence. In a few hours after its appli- 

 cation, if strong enough to kill the insects, it destroyed the plant also. In 

 every case it proved a failure. — James Donald. 



Chamovnle, for destroying scale on plants, has been tried, at the recom- 

 mendation of Sir C. M. L. Mouck, Bart, F.H.S. The Chamomile in a green 

 state was suspended among the branches attacked by the scale ; but no altera- 

 tion could be perceived, nor was the least effect produced upon the insects. 

 To ascertain whether or not Chamomile water possessed the power of destroy- 

 ing scale and other insects on plants, the Chamomile was infused in boiling 

 water, and when cold applied to the plants with a syringe. No difference 

 could be perceived. No scale was destroyed. — James Donald. 



Corrosive Sublimate, to destroy aphides and other insects. — -This was dis- 

 solved in water, and applied to the plants with a syringe. The insects were 

 killed instantaneously ; but, when the solution was made strong enough to 

 kill insects, it destroyed the plants also. — James Donald. 



Naphtha, Whisk;/, Oil, as remedies for the scale.— These substances were 

 all tried separately to dift'erent plants ; applied with a camel-hair brush, and 



* The following was the advertisement circulated by this person : — 



" The Proprietor is in possession of the means for the certain Destruction of the above noxious 

 Worm, and other Insects, whicli so often blight the liopes of the Agriculturist, by tlie very 

 heavy loss occasioned to tlie green crops, both VVlieat, Turnip, Cabbage, &e. The "Proprietor 

 having made various experiments with most respectable individuals, is confident the prepara- 

 tion will perform that which lie has above stated, and that the quantity of 1 cwt. mixed with 

 double the quantity of Sand or light Mould, to the Acre, will be all that is required."
