MINERALIZATION OF THE BONES 
The &quot; fossilization &quot; of the human bones from the Vero deposits 
is, as already mentioned, somewhat unequal. On attaining permis 
sion from Dr. Sellards, two fragments of fair size, one from the 
Vero Skeleton I, designated No. 5201, and the other from Skeleton 
II, designated No. 6957, were subjected for chemical analysis to 
Dr. E. T. Wherry, assistant curator, Department of Geology, United 
States National Museum. Besides these, Dr. Wherry was given 
part of a recently received Indian humerus from the Perico Island, 
Tampa Bay, Florida; part of a rib from the mineralized skeleton 
from near Osprey, west coast of Florida, for many years in the 
possession of the National Museum ; and part of an ulna from an old 
surface communal burial on one of the keys off Little Sarasota Bay, 
Florida. This last specimen, taken entirely at random, was to serve 
as a &quot; trial horse &quot; for Dr. Wherry ; but as its analysis proved to 
be uncommonly interesting, it is included in the report. 
The results of the analyses show a difference in mineralization 
between the bones representing the tw r o Vero skeletons. They show 
the presence in both of considerable organic matter. They differ 
quite markedly from those made for Dr. Sellards. 
A comparison of the results with those pertaining to the three 
bones of undoubted Indian derivation and antiquity measurable only 
by a few hundreds of years, shows that one of these is much more 
mineralized than either of those from Vero; one, that taken at 
random from our collection, very closely approximates the bone 
from Skeleton II ; while the third shows somewhat lesser changes. 
It is plain there is nothing in the results of these analyses that 
would point to any great antiquity of the Vero specimens. 
REPORT ON THE ANALYSIS OF THE BONES, BY EDGAR T. WHERRY 
&quot; The fragments submitted showed more or less admixture of sand 
and clay; these impurities were removed as fully as possible without 
destroying any notable amount of bone substance, and the bones were 
powdered in an agate mortar and analyzed as follows : 
&quot; For determination of all constituents except fluorine a 0.4-gram 
sample of each specimen was weighed out. heated for 2 or 3 hours at 
110, and the loss in weight recorded as moisture. The sample was 
then ignited for an hour over a complete combustion burner, and the
