Washington March 21st. 1807
I was going to send you the enclosed when I received your valuable present of the Camera obscura, accompanied by a note still more valuable. You have conferred upon me nothing but benefits. This additional kindness renders me at a loss how to express what I feel towards you. I cannot do it in words; but the opinion and the regard that prompted this new proof of your sentiments towards me are felt & valued as the highest honor I have ever received, or can ever deserve.—
I hear with extreme pain that your indisposition continues.—The change of air to that of Monticello will no doubt be your most certain & agreeable cure. Accept my sincerest wishes for Your health & my most grateful acknowledgements for your favor
I am with the highest respect Yrs
B Henry Latrobe
