Haywood' found traces in domestic strawberries and 0.1088 
per cent. in the ash of wild strawberry (/vagaria Virginiana). 
Langenbeck speaks frequently of its occurrence in clays. It 
has been found by the writer rather widely distributed in the 
clays of this state.” While Roscoe and Schorlemmer state 
that ‘‘It does not appear to forma part of the animal and veg- 
etable kingdom,” Wait® assumes that it is assimilated by 
plants. The writer’ shows its presence in peat. As the clay 
substance therein is comparatively small its presence can 
scarcely be attributed to that. F. Garrigon found traces in 
mineral waters. 
No statement in the literature has been found of its pres- 
ence being noted in the ashes obtained from the animal king- 
dom. ‘The ash fromincinerated fresh beef, beef bone, human 
flesh, and bone free from dirt, have been examined in this 
laboratory with the following results: Beef bone 0.0195 per 
cent.; beef flesh 0.013 per cent.; human bone’ a trace; human 
flesh® 0.0325 per cent. titanic oxide. 
A private communication from Dr. J. L. Howe concerning 
the work of some of his students states that ‘“Toole found 
titanium in abundance in dead bones, but only traces in fresh 
bone and muscular tissue, though traces were undoubtedly 
there.” Dr. C. EK. Wait in a letter of recent date writes: 
‘‘Since my note on titanium was published a year or so ago, I 
have made an examination of a large number of bodies and 
I believe that the element was found in nearly all of them. 
I have made a large number of estimations of titanium in 
vegetable bodies, and later took up the examination of animal
