I continue to be carried along by all your good wishes - I can't tell you how much they help.
,Just to give you an update. The farmer has had a small hole drilled into his skull and a biopsy taken.
How long it will take for results apparently depends upon what kind of tumour it is. In the meantime he is home, rather weak and only able to do very little. Each day he tries to walk a little bit further with the dog and he is now feeding the hens. He is on reducing doses of steroids and his language has stabilised to some extent so that although he forgets words he is nothing like as bad as he was. He sends thanks to you all too.
God bless you all for thinking of us.
