itself,-— in fine Chinese paper, — then pack them away in a large 

 box, with their locality and with care, but never put by a box that 

 is not quite full, without putting some cotton or other soft substance 

 to fill up the box, for such tender subjects should not have a play 

 during the transit home from where you collected them. 



In the rivers, canals, lakes, ponds, and small streams, you 

 will fiad many species of shells, which, although not handsome 

 are very interesting, and many of them will prove valuable here 

 in England ; therefore, do not leave a single one of them behind, 

 as it may be a cause of regret hereafter. Some of the shells 

 which you will find in the above-mentioned places are of the same 

 form as the land shells, others are like our fresh-water mussel, or 

 cockle : they are mostly found in the mud, sometimes in deep 

 water. You will be sure to find dead ones on the banks of the 

 lakes and rivers, and if you cannot procure them yourself, show 

 the natives the dead specimens, and offer them money to bring 

 you a quantity of them ; and the same with every other subject of 

 natural history — don't think of a few dollars when you will make 

 pounds of them ; but be not too lavish of your money with them — ■ 

 it will alarm their cupidity, and they will seek for more. I am 

 certain that when the natives see that you are collecting these 

 things, they will soon bring them to you, as they love money and 

 do not value the articles you are seeking. 



The rivers and pieces of water abound with shells : be diligent 

 in seeking them ? and your labours will be most amply repaid. 



When you have collected the fresh- water shells, place them in 

 a vessel and pour a large quantity of boiling water on them ; they 

 do not require to be put into cold water before the hot water, as 

 the land shells. As soon as the water is a little cool, pour it off, 

 and take out the animal as before mentioned. Wash them, &c, 

 but as the bivalve or fresh-water mussel will open wide as soon as 

 the animal is out, you must tie them close with care before you 

 put them out to dry if you do not the hinge will break, and make 

 the shell in part valueless. Some of the fresh-water shells, that 

 are like the snails, have a mouth-piece, which you must take great 

 care of, and keep these mouth-pieces by themselves, — that is, each
