do hereby declare the nature of said Invention for "IMPROVEMENTS IN CELLS
to be as
OR TROUGHS FOR OBJECTS OR PREPARATIONS FOR THE MICROSCOPE
follows:-
The object of my Invention is to provide a simple and efficient construction of
cell or trough for objects or preparations for the microscope whereby leakage and
the destruction of the preparations which the uncertain methods hitherto employed
are liable to are prevented.
According to my Invention I construct the cells or troughs (for containing the
objects or preparation) of glass, porcelain, Vulcanite, Gutta Percha, Ivory or any
other suitable substance or material that is capable of resisting the action of the
liquids or materials. employed in the mounting of objects and preparations-The
cell may be formed in one piece by moulding stamping turning or otherwise and of
any desired shape such as square circular oval or any other form to suit the class
of objects or preparations they are intended for-In all cases however the cells are
provided with a rabbet rim collar or margin for the reception of a covering glass
to seal up and complete the preparation-The glass having been cemented
properly to the rim after the object is placed in the Cell the preparation is ready
for use and perfect security is obtained from leakage owing to the cell being in
one piece.
The cells or troughs may be attached to ordinary glass or other slips or slides
and they may be used singly on the stage of the microscope in a grooved holder
from which they may be removed to be replaced by others as required.

I MATTHEW HENRY ROBSON of 18 Albion Place Newcastle on Tyne do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of my Invention is to provide a simple and efficient construction
of cell or trough for objects or preparations for the microscope whereby leakage and
the destruction of the preparations which the uncertain methods hitherto employed
are liable to are prevented.
According to my Invention I construct the cells or troughs (for containing the
objects or preparation) of glass porcelain vulcanite gutta percha Ivory metal or any
other suitable substance or material that is capable of resisting the solvent or other
action of the liquids or materials employed in the mounting of objects and
preparations The cell may be formed in one piece by moulding stamping turning
or otherwise and of any desired shape such as square circular oval or any other
form to suit the class of objects or preparations they are intended for. In all cases
however the cells are provided with a rabbet rim collar or margin for the reception
of a covering glass to seal up and complete the preparation. The covering glass
having been cemented properly to the rim or the like after the object is placed in
the cell the preparation is ready for use and when the cell is made in one piece
perfect security is obtained from leakage.
The cells or troughs may be attached to ordinary glass or other slips or slides and
they may be used singly on the stage of the microscope in a grooved holder from
which they may be removed to be replaced by others as required.
The accompanying drawing represents at Figures 1 and 2 in longitudinal section
and plan respectively a cell or trough made according to my Invention and Figure 3
is a view like Figure 1. but drawn to a considerably larger scale-The cell or
trough proper is marked A and the rim recessed collar or marginal part herein-
before described is marked a.- -B is the covering glass and O is the slip or slide to
which the cell or trough may be attached.
In Figures 1 and 3 the cell is shewn as being formed with a base in one piece
with the rim, but the rim may be formed without a base and the base be constituted
by the slip or slide as illustrated by Figure 4.
Or the rim may be made up of separate rings which may be separate from each
other and from the slide or one may be formed on the slide as illustrated by
Figure 5.
i
The marginal collar or rim a materially assists the manipulator when mounting
objects or preparations of any kind as it holds the covering glass B in its exact
position protects its edges and when a 'fluid medium is used prevents air bubbles
which if present would destroy the appearance of and render imperfect many
objects otherwise carefully prepared; it also enables the most difficult and
intractable media to be employed with ease and certainty.

page_text: When practicable a groove will be run round the base of the cell wall as at d to
lighten it and when it is to be permanently attached to a slip or slide to serve as a
cavity for the cement used so that no external ring of cement or varnish is needed
to secure complete adhesion.
A considerable saving of time is effected, as in the ordinary method of
construction it requires a lengthened interval for the cement to set or harden before
the preparation can be sealed and completed, with my cell the fluid medium and
preparation may be introduced at once and sealed, its completion being simply
dependent upon the drying of the varnish or cement employed in attaching the
cover glass effectually after which there is perfect security from leakage.
The process being so far simplified that an ordinary amateur may mount objects
neatly cleanly and expeditiously in fluid and with more security than an expert
can effect by the method hitherto in use.
Having now particularly described and ascertained the nature of my said"
Invention and in what manner the same is to be performed I declare that what
I claim is
Microscope cells or troughs made substantially as herein before described and
illustrated by the Drawings the essential feature being the rim or margin α or its
equivalent for the purposes described.
