Abstract
A beaker filled with ice cubes and water is covered with a plate of sheet metal. Over this is placed a paper embedding boat full of molten paraffin, and an inch or two above it is held a 60-watt soldering iron. The height of the soldering iron is then adjusted so that the paraffin at the lower half of the embedding dish becomes semisolid and the upper half stays liquid. By means of warmed forceps, the specimen is transferred to the dish, where it sinks to the top of the semisolid layer. Here, it is oriented by means of a warmed dissecting needle in relation to a pencil mark previously made on one side of the paper boat. One may take as long as he needs to orient the specimen, and several specimens can be oriented one after the other in the same dish.
