Some say this singular complaint, which was un¬ 
known to their ancestors, has only prevailed since 
they have been visited by foreign shipping. It 
does not prevail among the inhabitants of the sur¬ 
rounding islands ; but whether it be of recent 
origin or not, in Tahiti it is very affecting to wit¬ 
ness the numbers that have suffered; and we 
cannot but hope that as industry and civilization 
advance, and their mode of living improves, it will 
in an equal ratio disappear from among them. 
Blindness is frequently induced by the same 
disease that precedes the spinal curvature. The 
condition of the blind, when suffered to live, must, 
under the reign of idolatry, have been truly 
lamentable—they were generally objects of deri¬ 
sion and neglect, if not of wanton cruelty.

who can neither speak nor hear distinctly. 
In their application to particular diseases, the 
priests manifested considerable acquaintance with
