It may be hung up in the meantimeby a string attached to the neck; and a thin piece of wood, SKELETONS OF BIHDS 47 tied securely to one of the Larger bones (the coracoid, forinstance, as in Fig. 26), should bear a catalog number, writtenwith a very black lead pencil. The data to be entered in the catalog are much the sameas those for a skin: Sex (determined by dissection when dis-emboweling the specimen), locality, and Fig. 26. Rough skeleton of a francolin, dried and bundled togetherfor packing. The tag is of thin wood, bearing a number written withsoft lead pencil. To avoid all difficulties with beetles (Dermestes, etc.)which swarm upon dried bones in all tropical countries, dipthe whole skeleton, as soon as it is thoroughly dried, into aweak solution (of merely milky tint) of arsenical soap, andhang it up again to dry. If the beetles are allowed to eataway the Mesh, many of the smaller bones may be separated,and are almost certain to be lost. For added protection thedried skeleton may be sewn in a piece of cotton cloth. 48 SKELETONS OF BIRDS Unless there are special reasons to be considered to thecontrary, the first specimens of any species will always bepreserved as skins. Afterwards, if the skeleton is believed tooffer points of interest, a few adult specimens, which have notmany of their bones injured, may be prepared as has already been explained, however, that s
