Density measurements of molten solutions of thallium
and tellurium have been made over the temperature range
220 to 650°C and the composition range 31 to 69 atomic
per cent thallium. The Archimedian method was employed
since it is readily adaptable to performing measurements
over wide ranges of temperature and composition...

The 69 grab samples yielded 78,395 individuals which were separated
into 282 taxa, including 108 species...
