A technique is described for the floatation and enumeration of trematode eggs. A special sampling and mixing pipette has been designed. The floatation fluid is a solution of potassium mercuri-iodide (K2HgI4). A modified McMaster egg-count slide, or else a calibrated sliding toppiece apparatus is used for counting the eggs and estimating the number per gramme of faeces. The apparatus is illustrated and described.
