  Attention is drawn to the fact that some publications state or imply
incorrectly that the BCS-Bose gas transition was first studied by Leggett in
1980, whereas I published a paper on this subject in 1969. Attention is also
drawn to evidence from colleagues and myself in the 1980's that a ceramic
sample of 3% Zr-doped SrTiO3 was on the Bose-gas side of the transition. This
was, I think, the first example of a sample of any material which reached the
Bose-gas regime, and also gave a world record by a factor of over one hundred
for the lowest carrier concentration (~10^15cm^{-3}) at which superconductivity
(or strictly the beginning of a transition) has been observed to occur.
