Patent Offices, 24, Rue du Mont Thabor, Paris, in the Empire of France,
and 38, Porchester Terrace, Bayswater, in the County of Middlesex,
Patent Agent, for the Invention of "IMPROVEMENTS IN DISSECTED MAPS
AND CHARTS."-A communication by François Auguste Laurecisque,
Gentleman, residing at Passy, in the Empire of France, aforesaid..
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 24th April 1865, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 24, Rue du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
DISSECTED MAPS AND CHARTS," communicated to me by François Auguste
Laurecisque, a person resident at Passy, in the Empire of France, aforesaid,
and have petitioned Her Majesty to grant unto me, my executors, administra-
tors, and assigns, Her Royal Letters Patent for the same, and have made
solemn declaration that it is a communication.

page_text: NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification under my hand and seal
fully describes and ascertains the nature of the said Invention, and the
manner in which the samo is to be performed, that is to say:-
This Invention consists in a new or improved system of cutting out, fitting,
and illustrating maps and charts for the study of geography, orography,
geology, hydrography, and other analagous sciences. This method of cutting
out and fitting allows of rendering moveable whole maps in one single piece,
comprising only elements of the same nature, and of placing these maps or
pieces of maps oue in the other to any number desired or required by the
subject. It consists in leaving on each map a part in relief representing any
particular element, which part is cut out from the others, and reciprocally, so
that the superposition of a series of maps or parts of maps thus prepared and
fitted one into the other forms a complete map showing the distinct elements
of the superposed charts, thus for geological study, for example, each map
comprises and shows only one or part of one of the strata composing the surface
of the globe, so that all the maps of the series form together a complete
geological chart.
The method of illustrating consists in placing at the back of each
detached piece representing a state, territory, county, town, or other division,
and in the space circumscribed by a projecting flange or band applied at
the back of such piece and around its outlines for fixing it into the piece
placed below it, a note or manual, or printed or written book concerning
the state, territory, province, county, or other natural or political division.
The application of these improvements constitutes what I call mnemo-
technical geography, and may be resumed under the following heads :-
Firstly, a mountain chart and river system chart composed of four maps
sliding one in the other by means of the system of cutting out above described,
representing four series of distinct elements, suitable for progessive study and
teaching.
Secondly, a moveable geological map, comprising at least seven maps one in
the other by the same means of cutting out, representing a series of elements
by groups corresponding to the different terrestrial strata.
Thirdly, a map formed of pieces divided into geographical elements, alone
or in groups, each of which is provided at the back with a note or manual
giving the population of the principal towns, the agricultural, commercial,
and industrial productions of each country or district represented by said
piece, as well as the statistical or historical particulars relating to it.
These improvements having for object to render moveable entire maps or

page_text: parts of maps comprising orographical, hydrographical, geological, and other
elements are applicable to all states or parts of states in all parts of the
world. I reserve myself the right to apply them for showing in a
historical point of view the successive augmentations of territory which have
presided at the formation of the different states, and, in a strategical
point of view, the conquests which have from time to time modified the
circumscriptions of these states, as well as the changes which have been the
consequence.
Having thus described the nature of the said Invention, and the manner
in which the same is to be performed, what I claim is, ―
Firstly, the means of rendering moveable entire maps prepared for the
study of geography, geology, hydrography, orography, history, and analagous
sciences by cutting out or removing from some of these maps certain parts
representing elements of a similar nature, while allowing these parts to subsist
on others, and reciprocally, so as to be able by superposing and placing them
one in the other to form a complete map or chart.
Secondly, the mode of illustrating dissected maps or charts by placing
at the back of the pieces of which they are composed, and in the com-
partments circumscribed by a projection, flange, or cord following the
outline of each piece, and serving for fixing it on that beneath it, a note
or manual containing statistical, historical, geographical, or other infor
mation relative to each state, territory, or other division represented by these
maps.
The whole substantially as above described.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Thirty-first day of March, in the year of
our Lord One thousand eight hundred and sixty-five.
