of fublimate mercury {&)> and kept during the paf- 

 fage in a cool airy place. In this manner tea- 

 feeds, the tones of mangoes, and all hard 

 nuts and leguminous feeds in general, may be 

 prepared. 



(b) In (lead of putting fmall feeds in bees-wax, 

 they may be enclofed in paper or cotton which 

 has been firft fteeped in melted bees-wax, and 

 then placed in layers in a chip-box, fome of which 

 may be filled as before with melted bees-wax. 

 Pulpy feeds, as thofe of ftrawbenies, mulberries, 

 arbutufes, Sec. may be fqueezed together and 

 dried, and then put into the cerate-paper or cot- 

 ton above-mentioned. 



(c) Small feeds, may alfo be mixed with a lit- 

 tle dry fand, put into the cerate-paper or cotton, 

 and packed in glafs-bottles, which are to be well 

 corked, and covered with a bladder or leather (e). 



{d) Sublimate mercury is the raoft effectually diffolved in the 

 acid of fea-falt; one drop of which will dirTolve one grain of 

 mercury, which will afterwards mix with water. One drachm 



of fublimate will be fufficient for half a pint of water. 



Corrofive fublimate may likewife be diffolved in a faturated 

 folution of fal ammoniac in water, one ounce of which will dif- 

 folve twenty fcruples of fublimate. 



(e) This may be compared with what Dr. Hawkefworth ob- 

 ferves in his Voyages, vol. ii. p, 123. " On the 10th I put 

 fome feeds of melons, and other plants, into a fpot of ground 

 which had been turned up for the purpofe : they had all been 

 fealed up, by the perfon of whom they were bought, in fmall 

 bottles, with roftn, but none of them came up except muftard ; 

 even the cucumbers and melons failed, and Mr. Banks is of 

 opinion that they were fpoiled by the total exclufion of frefti 

 air." Some feeds which I received from North America* 

 enclofed in corked bottles, have fines been fowri, and germi- 

 nated. See g.
