I have had great difficulty in finding where this particular gravestone is to be found. I have taken many photographs in the past, and with the greatest help from the staff. But there is now a couple of very suspicious characters in place there, who have menaced me on my recent visit to find caird's stone.I found the secretary's office and he sent me a compliment slip with the location plot 270, section NN, but where it is I do not know, without a general map of the various sections. My purpose is to give details of Edinburgh University professors, which no one else seems to have thought of doing.Some of the best graves which had bronzes have been stolen? or perhaps removed by the self same staff, it is possible, I suppose.
