Can anybody translate a bit of this old letter for me?

I've been trying to translate this letter for years. It was written about 150 years ago by my great-grandfather and I have been wondering for years what it says. I do not understand a word of arabic. If someone can translate even one sentence of the document, it would be greatly appreciated. ( The picture is on my profile, under photos. There is only one photo, and by the way, it is a little fuzzy because I photocopied it). Thanks!
