(Chapter 39) Footnote 2:

The illustrated capital at the head of this chapter illustrates the placement of the leaching box in a stream. The 1543 edition shows three men doing this job; in the 1555 edition it is performed by four putti. For a colorful account of pre-Vesalian preparations of cadavers for skeletal study, see Alessandro Benedetti’s Historia corporis humani; sive Anatomice (1498-1502), Bk. 5 Ch. 23, translated in Lind 1975, pp. 132f. The use of a leeching box may have originated as a way of avoiding Pope Boniface’s Bull against dismembering bodies, issued in the 13th century to prohibit the practice of transporting bodies from abroad for burial at home.
