%X Based on <i>¦Ì</i>-, <i>T</i>- and <i>H</i>-dependent pairing and number
equations and the premise that <i>¦Ì</i><span>(<i>T</i>)</span> is predominantly the cause of the variation of the upper critical field<i> H<sub>c</sub></i><sub><span>2</span></sub><span>(<i>T</i>)</span>, where <i>¦Ì</i>, <i>T</i> and <i>H</i> denote the
chemical potential, temperature and the applied field, respectively, we provide
in this paper fits to the empirical <i>H<sub>c</sub></i><sub><span>2</span></sub><span>(<i>T</i>)</span> data of H<sub>3</sub>S reported by Mozaffari<span><span><span style=\"font-family:;\" \"=\"\">,</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> <i>et al.</i> (2019) and deal with the issue of
whether or not H<sub>3</sub>S exhibits the Meissner effect. Employing a variant
of the template given by Dogan and Cohen (2021), we examine in detail the
results of Hirsch and Marsiglio (2022)</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">who
have claimed that H<sub>3</sub>S does not exhibit the Meissner effect and
Minkov</span></span></span><span><span><span style=\"font-family:;\" \"=\"\">,</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> <i>et al.</i></span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">(2023)
who have claimed that it does. We are thus led to suggest that monitoring the
chemical potential (equivalently, the number density of Cooper pairs <i>N<sub>s</sub></i> at <i>T</i> = <i>T<sub>c</sub></i>) should shed new light on the issue being
addressed.</span></span></span>
