igo Mr. Knight's Experiments and Observations , &c. 
were the purple Frontigniac, possessed their musky flavour, in 
the same degree with others growing on the same plant. 
There is another experiment in my last Paper, which I will 
also notice here, because it appears to lead to some important 
conclusions, and had been tried only in a single instance. I 
have there stated, that the stem of a young tree became elliptical, 
by being confined to move only in the segment of a large circle. 
This experiment was successfully repeated, during the last year, 
on other trees ; but I have nothing to add to the description 
which I have already given. 
I am, &c. 
T. A. KNIGHT.
