Included among the miscellaneous personal artifacts recovered from the “Tortugas” shipwreck are a series of 13 probable bone, but possibly ivory, small cylindrical hollow objects, all seemingly unused (L. 0.7cm, W. 0.8cm. Diam. of hole 0.5cm; Fig. 81). It has been proposed that these unusual objects represent spare joints for an undetermined form of utensil or instrument, potentially medical, such as enema syringes which were commonly used in the 17th century.
