It differs principally, however, and has a much broader field of usefulness in that, instead of using normal erythrocytes and making smears for examination, a suspension of the red corpuscles of the hen carefully titered is used as a standard and this suspension mixed in known proportion with the elements, i.e. patient's erythrocytes, leukocytes, etc., to be counted allows for examination and comparative enumeration under the microscope. He points out the following distinct advantages: (1) it can be used with equal facility for counting . . . [Full Text PDF of this Article]
