1892.] Investigation at Tick Island. 575 
PATHOLOGICAL SPECIMENS. 
In the former excavations a number of tibie were found 
with marked anterior curvature and increase in the circum- 
ference of the bone with roughened surface. But one of this 
nature was met with upon the last visit to Tick Island, at five 
and a half feet from the surface and twenty-five feet from the 
margin of the base of the mound. 
PERFORATED CRANIA. 
One cranium with perforation at parietal eminence .7 in. 
antero-posteriorly and .6 in. transversely was the only skull 
found showing perforation and in this case the uneven mar- 
gin showed it to be the result of a blow from a pointed instru- 
ment, having nothing in common with the round and even 
perforations found in Vapo of two crania during previous 
investigations. 
POTTERY. 
Throughout the entire upper stratum were found fragments 
of pottery, the large majority undecorated but some ornamented 
with parallel lines.
