Hartzoeken wrote upon the subject the following year, and asserted that he had seen these animalcules three years before they had been observed by Hamme.
In a former paper I have recorded recent observations, where animalculesof a peculiar description were found in the purulent secretion attending various affections.
The existence of animalcules in the generative secretion was first noticed by Lewis Hamme, a young German student, and shown by him to Leeuwenhoeck, who published an account of them.
He had been writing and speculating upon saliva, and had searched the saliva of the human mouth foranimalcules without finding any.
It then occurred to him to ask whether the teeth might lodge animalcules discharged from the salivary ducts.

Attached to the weed is a colony of those peculiar animalcules known popularly as 'bell-animalcules,' and to the naturalist as Vorticellae.
And when a portion of the weed is placed under the object-glass of the microscope, numerousanimalcules are to be seen waving backwards and forwards in all their vital activity.
Thus it can digest food; for in the bell-animalcules and their neighbours, the food-particles swept into the mouth are dissolved amid the soft matter of the body in which they are imbedded.
Their colonies and those of neighbour-animalcules may be detected by the naked eye existing on the surface of pond-weeds as a delicate white nap, looking like some lower vegetable growth.
