Help with a death certificate

[blamcca]

I have another Scottish death certificate this one is from 1921.
This one's hand writing is quite atrocious, I have made out what most of it says except for these three columns- When and Where Died, Cause of Death and Informant.
Hope some one can help make sense of this.

I'll take a stab at the first column - I'm sure corrections will follow 

1921
January
Eleventh
.. 30 m. PM
Royal Asylum
Edinburgh Usual
residence 13 Waverley
Street, .........

[Alexander.]

Cause of death -

Chronic Valvular Heart Disease
5 yrs 9 mos. 15 days
Senile Decay
ArterioSclerosis
As cert. by W. McAlister M.D.

[Alexander.]

The time of death is a bit tricky, but I think it is "4h. 30 m. PM".

Usual residence was "13 Waverley Street, Falkirk".

Informant - possibly R. G. Nelson?

Thanks sami, that was about what I got to 
Freckneale, thanks wasn't completely worried so much about the informant or exact time of death so don't worry about it
