This kind of monstrous pigs, produced by the unnatural situations of parts 

 by some external compression, I believe is very frequent : I had another of the 

 same kind sent me out of Derbyshire, which had a resemblance of a man's face, 

 and all the other parts of a pig, and this had the same chin, and depression be- 

 tween the eyes, the roundness of the head, and flatness of the ears above described, 

 only that this wanted hair, as pigs which come too soon do : and no sex could be 

 distinguished in it. 



At Thorpe, two turkeys were taken out of one egg, which was not observed 

 to be larger than ordinary; they grew together by the flesh of the breast bone, 

 but were in all other parts distinct ; the two heads, four legs, four wings, and 

 two trunks of the body appeared something monstrous ; but it was evident that 

 the monstrosity was only two turkeys sticking superficially together, and both 

 seemed less than the ordinary size of turkeys ; there wanted both nutriment and 

 room for the growing of both turkeys, which was the occasion of their cohesion 

 and smallness. These turkeys had distinct cavities in their bodies, and two 

 hearts; so that they had two distinct cicatriculas, and consequently the egg had 

 two yolks from whence they were prorluced; vvhich accident is very common. I 

 have a dried monstrous chicken, which has but one head, four wings, four legs, 

 and one cavity in the body, and consequently had but one heart; in this case 

 this monstrous chicken was produced from one cicatricula, and consequently 

 one heart. So Paraeus mentions a double infant with one heart ; in these cases 

 the original of the infant was one, and the vessels regular, but in the extremity 

 the arteries and nerves were divided into more branches than ordinary, and pro- 

 duced double parts ; and this is like the double flowers of plants, which are pro- 

 duced so by the richness of the soil. 



As the two yolks of eggs are joined in the ovarium, and covered with one 

 skin ; so the eggs of quadrupeds are joined in the ovarium, and as they grow 

 their bodies externally cohere. So that there are these two reasons for the 

 multitude of the parts in an embryo ; the joining of two perfect animals, or else 

 the extraordinary division of the original vessels, the arteries and nerves. 



An Account of Maryland. By ike Rev. Mr. Hugh Junes. N" 259, P- 430. 



Chesapeak-Bay, which runs N. and by W. about 200 miles or more, ilivides 

 this province, as well as Virginia, into two parts, called the eastern and western 

 shores. The land is generally low on botli sides. No hill that I have seen or 

 heard of is 50 yards perpendicular; but about lOO miles back, or west of us, 

 towards the heads of rivers, the ground rises, and appears in very high moun- 

 tains and rocky precipices, running north and south, from the top of which a 

 man may have a clear prospect of Virginia and Maryland. All the low land is
