All parts intended for preservation, previous to their being put into spirits, should be macerated in water to extract the bloody colour; and the water changed from day to day, as long as the part will bear it without putrefaction, or until it becomes quite colourless; and should be freed by dissection, from all surrounding unnecessary cellular membrane, adeps, &c. which may obscure what is intended to be shewn. It should be then suspended in spirits, in a position the most favourable for exhibiting its principal parts: if it should be an hollow preparation, as a bladder, hydatid, intestine, &c. or if it should have any hollow parts, cavities, or sinuses, necessary to be shewn, such should be distended with curled hair, wool, cotton, or the like; small blood-vessels, ducts, &c. are sometimes shewn by the introduction of bristles, quills, or bougies. In this way, the several parts being put into their natural position, and suspended in spirits for a week or tea days, according to the bulk of the preparation, they become much harder and firmer in their texture; so that they will retain their position, when the hair, wool, cotton, bougies, &c. are removed, to shew the hollow parts which have been distended by them. The preparation should then be put into a ...
