Hi Lynn
You now need to contact Highland Archives. They do not allow you to look at the registers in person as there could be information pertaining to others, but they will do the search and also copy and print out the relevant pages. The patient needs to have died 75 (or more) years ago to get any information though.
I wanted to know about a man who had died on 21st July 1936 and ontacted them 21st July 2011. I was able to get dates and also a lot of family information from the admission forms. The reports from the two certifying doctors and the Sheriff Court's warrants were also attached.
Having those dates, and because of the area the man was from, I can now check the Police Log Books which should give even more information. Strangely, the time limit on the Police Log Books is only 65 years so I could have checked them earlier. They need checked in person though and the ones I need are held in Portree!
It cost £28 in total. As I recall, the first 20 mins were free but they then charge £20 per hour, plus the cost of printing.
