I was amazed, when I logged on after breakfast, to see so many postings - thanks to all who have contributed, for your interest and ideas, and for the offers to pass on the image for others to puzzle over.
A very kind person in Australia (also related distantly to James Page, author of the notebook) was kind enough to send me a mass of material, without which I would not have been able to find out so much about his life. She tells me that the pages of shorthand come immediately after a page containing two drawings, uncaptioned - one shows two koalas up a tree, and the other shows a couple of settlers' cottages. Appaently James was in the habit of making trips into the country round Adelaide - around this time he moved out to Mitcham in the hills. I think you are right - the longhand writing is Bridge Water Hotel - I had already deciphered Mrs Robinson.
Whether the writing is in English - I have no way of knowing, though I would have thought it likely. Interesting poing - if he had wanted to keep the contents of this note secret, he could simply have written in one of his other languages: his obits mention that he knew several. James was, among other things, a consular representative for France and Switzerland.
As far as I can make out from a quick Google - Dacomb shorthand was later than 1876, its inventor born in 1863. The Wiki article on shorthand mentions a German 'Gabelsberger' system from 1834 ...
Again, so many thanks to all for your interest - and for continuing to spread the image among those who might hold the key
