drawing he wished to send to you, as it would have been possible to have done, in
a letter: and I had taken it at one time for that purpose: but his thinking of an
occasion which might occur of producing it before her Majesty &c put by the sending
it for the present. His intention was then to endeavour so to do through the
channel of Mr Fitzherbert upon their return: but I know not but you may
have a powerful rival in the Grand Duke, who having heard of the barge, has
desired to have some kind of representation of it, though my Brother is not yet
acquainted with his Imperial Highness's pleasure.

Of the mode of junction I know not how to give you any tolerable idea
I do not perfectly understand it myself, the mechanism being mostly concealed
by the structure of the parts. The stern of the head link, for example, is
either concave or convex but unfortunately I can not remember which concave: the head of the 2d link is convex, fitting exactly into that concavity. In
the concavity, between the upper edge of the boat and the water, runs an
horizontal groove. The connection is formed by an iron bar which is
fixed in the 2d link, turning playing, I believe, there round a perpendicular fulcrum,
and running upon friction rollers in the horizontal groove in
the breech of the first link. The length of the bar is broken divided, as it were,
by a hinge, which lying horizontally; parallel to the horizontal groove,
of course gives f room for par [that part of the bar that is not fixed ]
the end of the bar opposite to that which is fixed, to play up and down
and consequently for the according to the motion of the link boat into which
it is inserted al by means of the horizontal groove. The hinge is
just perceived, as you look down between the two links boats: and the diameter
of it forms, I think, all the interval which there is in general between them:
but they are capable upon occasion of being let out to I don't know what distance:
I believe, a foot or more. All the other links are connected in the
same manner.
