Rafn on the * Cabinet d'Antiquites Americaines d Copenhague, 
1858/ and that it is said to be from the island of Porto Rico. 
A similar ring, but of lighter proportions and more finished 
workmanship, is in the magnificent collection formed by the 
late Mr. Christy. It is from the island of St. Thomas, and may 
have been obtained by Mr. Christy, in exchange, from the 
Copenhagen Museum. Its internal diameters are thirteen, 
and eight and a half inches. 
**The only other specimen known to be in this country be- 
longed to the late Sir Robert Schomburgk. It was sold on ist 
December, 1865, by auction at Stevens's, and is now in the 
museum formed by Mr. Blackmore, at Salisbury. Its internal 
diameters are twelve and a half, and eight and a quarter inches. 
"Dr. Wilson, in his 'Prehistoric Annals of Scotland' (vol. i., 
p. 222), engraves two stone collars, which are somewhat like 
the specimens in the Blackmore and Christy Collections, and 
are said to have been found near the parallel roads of Glen- 
Roy. Judging only from the engraving, they are, however, 
very much more likely to have come from the Caribbean 
islands. 
With regard to the probable use or purpose of these rings I 
can give no information, but shall be very much obliged for any 
suggestion, or for hints as to any works, likely to contain such 
an account of the customs of the nations at the time of the 
Spanish invasion, as may aff'ord a clue to the mystery. 
" Such elaborate pieces of work in hard stone could not have 
been intended to serve either a temporary or a trifling purpose. 
They are all far too heavy for ordinary use, but yet not heavy 
enough to kill, or even to greatly torture the wearer, if we 
regard them as collars of punishment. 
"Of the many suggestions I have yet received none seem 
applicable alike to each of the known examples, and I can only 
hope that my exhibition to-night may result in clearing all doubt 
on the subject." 
C 3'- 
The objects in this Case were all found in St. Domingo. Nos. 
I, 2, and 4 may have been used as anchors. No. 4 shows con- 
siderable wear near the drilled hole as if from its having been 
suspended with a cord. No. 3 is a stone which has been used 
for pounding maize. Similar specimens are shown from Cali- 
fornia, Case H 12, Nos. 6 to 9, and from the United States, 
Case C 33, Nos. i to 4.
