The cover-slip is sealed on the chamber with vaseline. Square. Fig. 4 Moist chamber and cardboard trough for closing open end of chamber. When the needles are in place (cf. fig. 3), the trough is placed over shanks of needles (dotted lines at open end of chamber) and filled with vaseline. cover-shps may also be used, if the rest of the chamber be roofed with other strips of cover-glass. The moist chamber is open at one end to permit the entrance of the microneedles or pipettes. To prevent undue evaporation, especially when a preparation is to be left over night, the open end may be temporarily closed by means of a paraffined thin card- board trough of a shape shown in figure 4. The trough is placed over the shafts of the needles and filled with soft vasehne con- taining a few threads of cotton to give substance to the vaseline. The vasehne closes around the shafts of the needle and seals the opening of the chamber without interfering with the movement.
