grain, as it appeared through the microscope; the extreme parts by c, and by 

 EP, a seeming orifice, which is the part where the string was broken off, and 

 by which both parts of the body were joined together. The concave bows or 

 circles that appear in the grain defg, are not natural, but adventitious to 

 it, proceeding only from the drying or shrinking up of the great number of 

 eggs that lie within the animalculum ; for if the grain were well soaked in water, 

 those concave parts would become convex, and be also more obvious to the 

 sight, as well as the stem of that string abovementioned. 



But on taking one of the largest grains, which is somewhat fiat, that part of 

 the trunk will not shrink inwards ; the reason of which probably is, that the 

 animalculum, before it was killed, had discharged most of its eggs. 



Fig. 8, HiK show an egg with its shell or membrane, as it was taken out of 

 a grain of cochineal, in which egg might be seen the young one within, and 

 the shell surrounding it. 



Fig. 9, LMN represent an unborn cochineal animalculum, which I had sepa- 

 rated from the egg-shell with a great deal of pains ; it lay with its back to my 

 sight, and in such a position as to show three of its legs. 



By fig. 10, OPGRS show a small particle of the vessels belonging to an ova- 

 rium or egg-nest; where may be seen divers broken filaments or strings, to 

 which the eggs were fastened, except the great vessel r, through which probably 

 several other vessels received their matter for the nourishment and increase of 

 their eggs, st shows a string to which the egg tv was fastened, as other eggs 

 were to the other strings before I broke them off. These strings opqrs were 

 almost transparent, and I could see other small particles in them when I took 

 them out of the cochineal grain, and separated the eggs from them ; but as 

 they began to dry, they assumed a reddish hue, and when they were quite dry, 

 they became of a light red colour. 



Fig. 11, wxYz represent another animalculum, which I also took out of its 

 egg-shell, in which the legs are to be seen very plainly, between w and x, but 

 I could not see that leg which lies upon the body. 



Fig. 12, ABCD is another animalculum, cleared of the egg-shell, in which 

 may also be perceived the legs between a and b. 



Fig. 13, EFGHi represents an animalculum lying upon a glass, as I had taken 

 it two days before out of a cochineal grain; it was not much altered by drying; 

 it had but two legs left, the other being broken off. In this animalculum there 

 appeared, at the extremity of the head, a crooked part g h, which I take to be 

 the instrument with which it extracts its nourishment out of the leaves of the 

 plant. 



Fig. 14, KLM represent a small part of the blood-vessels, which partly co-
