732 PHILOSOPHICAL TRANSACTIONS. [aNNO 1743, 



These emitted particles are very different from the small globules of oil, with 

 which the farina of the lily abounds ; for these diffuse themselves equally on all 

 sides, while those, on the contrary, go off in one continued train, like the 

 ejected pulp of a roasting apple ; and are involved in a filmy substance, as the 

 eggs of some aquatic insects are. 



He has since chosen the farina of a pompion to repeat this experiment on, 

 which is not of an oily nature ; and, on account of its size, may be conveni- 

 ently observed with the 2d magnifier, which has the advantage of a larger field. 

 He viewed some few of these also out of the many farinaceous globules, which 

 were within the area of the microscope, with the same success, and yet greater 

 pleasure : for he could plainly perceive, during the time of action, by 2 or 3 

 lucid specks in the centre of the globule, which continually shifted their places, 

 an intestine commotion within the farinaceous corpuscle, and a stronger ejacu- 

 lation of the emitted particles. 



Upon opening lately the small black grains of smutty wheat, which is here 

 distinguished from blighted corn, the latter affording nothing but a black dust, 

 into which the whole substance of the ear is converted, he perceived a soft 

 white fibrous substance, a small portion of which he placed on the object-plate: 

 it seemed to consist wholly of longitudinal fibres bundled together, and without 

 any the least sign of life or motion. He dropped a globule of water on it, to 

 try if the parts, when separated, might be viewed more conveniently ; when, to 

 his great surprise, these imaginary fibres, as it were, instantly separated from 

 each other, took life, moved irregularly, not with a progressive, but twisting 

 motion; and so continued for the space of Q or 10 hours, when he threw them 

 away. He is satisfied they are a species of aquatic animals, and may be deno- 

 minated worms, eels, or serpents, which they much resemble. He repeated 

 the experiment several times, with the same success, and gratified others with 

 a sight of it.
