Sarah Slater's death certificate

[Susan Higginbotham]

This is the death certificate of Sarah A. Spencer, formerly known as Sarah Slater. Can anyone read the cause of death? I can make out "chronic" on the first line and "nephritis" on the second line, but not the second word on the first line.

Note that even on her deathbed, Sarah was not forthcoming about her age! Evidently her relatives made their best guess when putting a birth year on her tombstone.
