EXPLOBATORY NOTICES FOB JUNE. 267 



placed on some soft paper, with several folds of waste 

 paper both above and below it, and the hot iron placed 

 on, being gently shifted as occasion requires. Great 

 care must be taken that the iron be not too hot, or 

 the specimen will be at once totally spoiled ; but if 

 due 'caution be observed, and the degree of heat 

 properly regulated, the juices of the orchis will be 

 speedily dried up, and the colours of the corolla 

 beautifully preserved. In short, the result will be 

 productive of specimens of superior appearance and 

 value. 



The long-living Sedum tribe, and the Heaths ( Galluna 

 et Erica), should be immersed in boiling water soon 

 after gathering, which will prevent their leaves drop- 

 ping off. If for curiosity, any species of Sedum be 

 preserved or hung up, it will continue to grow for 

 years. A specimen of Sedum rupestris, I gathered in 

 1839, on the cliffs at Chepstow, and then carelessly 

 left in a damp room, actually put forth flowers in 

 December, six months afterwards.
