they have grown, if this be not of a perishable nature 
De Candolle recommends that seeds from a moist coun- 
try should be packed in charcoal pulverized. Seeds 
of an oily nature may be packed in sand, if they have' 
to undergo long transportation, Fruits must be pre- 
served in spirits. 
A section of the trunk of any rare or interesting tree 
should be obtained. If the tree be not more than a foot 
in diameter, a section of the whole trunk may be pre- 
served ; if the diameter be greater, then the fourth or 
less quantity will be sufficient, being careful, however, 
always to embrace the pith, and to preserve the bark 
attached to the specimen. Its height or thickness may 
be about four inches. Labels should accompany each, 
as full in descriptien as for the specimen of plants. 
Concluding Remakes. — Great care should be taken 
to accompany each specimen by a label, indicating the 
locality, date, age, and sex. A good plan is to have 
blank labels with strings attached, on which may be 
written all these particulars, with the measurements, 
and fastened to the animals. Animals in spirits should 
have bits of sheet lead attached with a number corres- 
ponding to one in a full list. Names or numbers may 
be written directly on eggs. These should be packed 
in layers, separated by cotton. Mineralogical speci- 
mens ought to be wrapped singly in paper, and in ad- 
dition, enveloped in cotton when they contain delicate 
crystals. In packing up birds, each specimen had bet- 
ter be wrapped in paper separately. Skins of all kinds 
especially such as are expected to travel a great dis- 
tance, or ,to be delayed on the road, should have an 
abundance of camphor, turpentine or snuff placed 
among them. Boxes should be fastened very closely
