tinued for some time longer. To bleach the skeletons, mix about a 
drachm of chloride of lime with a pint of water, adding sufficient acetic 
acid to liberate the chlorine. Steep the leaves in this till they are 
whitened (about ten minutes), taking care not to let them stay in too 
long, otherwise they are apt to become brittle. Put them into clean 
water, and float them out on pieces of paper. Lastly, remove them
