Prof. 51 eKendrick, in his presidential address to the physiology section Of the British association, in September, remarked that t.m sum.lest particle of matter 1 ha, can be seen with our present mic: os.copns is between one-four-lumdrcd-t liousand 11 - : and one-five -hur.drrd-tlioiisaiid tit of an inch in diameter. The diffraction of light, in the microscope forbids the possibility of seeing still smaller objects.
