<p class="MsoNormal">Some history of the specimen’s initial treatment would be most helpful as John has suggested. &nbsp;pH 4 is the critical level for hydrogen ion activity, so you’re getting close and it obviously isn’t helping the specimen. &nbsp;<o:p></o:p></p>

<p class="MsoNormal">Beware of cosmoid scale loss as well as these can be squeezed out over time from their protein-based ‘pockets’ on the skin if these pockets start to shrink. &nbsp;If the specimen is preserved in alcohol then the scale loss can be repaired using
 Necolodine solution. &nbsp;Feel free to come back to me if you need any further advice or more detail and do send pics.<o:p></o:p></p>
