sheep, and the glandulous parts and water bladders as many. I have been often 

 considering, whether the opening of the tuba might not be to give way for the 

 evacuating some moisture, at the time the uterus is closed, and which cannot 

 get through the vagina, for I have sometimes found in the thin part of the tuba 

 near the opening a white matter, consisting of transparent globules, a little 

 larger than a blood-globule. 



There lately came to my hand a book, called Collectanea Medico-Physica, in 

 which, cent. 5, p. 8, are some words to this purpose. But it is most surprising 

 what the learned Bontekoe relates from the curious Lcewenhoeck, that the 

 sperm of men is full of small children, and so the sperm of other animals, ac- 

 cording to their kind. But this is a mistake, for I have only said it is full of 

 animals, or worms with long tails, whose figure I have often shown. For as it 

 is not proper to say, that worms swimming in the water are flying insects, 

 though they come from them ; or to say that the kernel of an apple is a tree, 

 though a tree comes from it; so it is no less improper to say, that the worms 

 in men's seed are children, though children come from them. It is often said 

 that a tree may be seen in the kernel of an apple ; but I must profess, that a 

 seed, besides the radicle where the root springs, consists of roundish trans- 

 parent globules, which when it grows, turn into cylindrical bodies, being vessels 

 to carry the nourishment to the radicle ; but when that is sufficient to draw its 

 nourishment from the earth, the remaining part of the seed does no more ser- 

 vice to the plant, but dries away. It is true, when we examine several seeds, 

 we find in them two or more beginnings of leaves, as small as a small sand; 

 these lie folded up, and show in a microscope like the beak of a sparrow; but 

 when they are unfolded, we then see the beginnings of other leaves, which grow 

 not till the root is larger. These last observations have been made on seeds, just 

 taken out of an apple, or a little dried. But if you cut up a Turkey bean, though 

 every so dry, the two leaves are visible to the naked eye; and if you use a mi- 

 croscope, you see the ribs or vessels of the leaves, for they are partly made to 

 stiffen it, and partly to carry nourishment for its growth, &c. 



Dissection of a monstrous double Cat. Read before the Dublin Society by Dr. 



Mullen. N° 174, p. 1135. 



This monstrous kitten was double from the navel downwards, having 4 hind 

 feet, 2 tails, 2 anuses, and 2 pudenda, for they were females. They were 

 joined in one trunk at the navel, and were continued so upwards ; but yet this 

 monster had 2 pair of fore feet, one of them on the back and the other on the 

 breast. The head, though single, had 2 pairs of ears, one naturally situated, 

 and another at the hinder part of the head, between the processus mammillares.
