Hello Farmtreebuilder,
I would ask SP for a re-scan because the one part impossible to make out is the maiden name of Archibald's mother. Death Certificates would normally give the mother's married name followed by her maiden name but there appears to be just one name here. I don't think anything has been rubbed out. Any changes on a Certificate would have a note in the margin initialled by the Registrar.
Here's my attempt. Not sure of the first letter in the Doctor's surname.
Sommervill, Archibald, Collier, Widower.
1859, June, Second. 9h 30m P.M. Poorhouse.
M(ale). 59 Years.
James Sommerville, Labourer, Deceased.
Margaret ------, Deceased. (Might be Irvine)
Dysentery, 3 Weeks, Simon ?urrock, M.D. June 2nd.
New Monkland Churchyard. James Hendry, Beadle.
(Signed) William Sommervill, His X Mark, Son. (Signed) John Macarthur, Registrar, Witness.
1859, June 3rd. At New Monkland. (Signed) John Macarthur, Registrar.
Regards, Dod.
