 a preservative solution before being laid in.* The ^re-

 Royal Gardens, Kew. 



* The preservative solution may consist of corrosive sub- 

 limate dissolved in spirits of wine, in the proportion of two 

 drachms to the pint. It is very poisonous, and should be kept 

 labelled, and used with care.
