VOL. XXIII.J PHILOSOPHICAL TRANSACTIONS. 51 



female children joined together from the neck to the navel; their picture was 

 with arms embracing, and legs twisted, all parts and joints entire to both; the 

 viscera also all double and perfect, the head only single, but appertaining to 

 both, and looking over the right shoulder of one and the left of the other. 

 They were born alive before 7 months. 



At Maestricht I went into the quarry, of which you have an account in the 

 Transactions, but it is more curious than there described, and larger, being 3 

 hours in length, and 1 in breath, and capable of sheltering 100,000 men. It 

 cost me a fit of an ague, through its excessive chilness. The stone dug from 

 hence is much like our kettering; the Jesuits have here a very fine chapel built 

 of it. 



Franciscus Linus's dials at Liege, the original of those formerly in our Privy 

 Garden at London, are shamefully gone to decay, none remaining of use, but 

 that which distinguishes the hours by feeling, and the globe which shows it in 

 all other parts of the world. 



At Namur there are no curiosities but such as are military, except only the 

 cachot cut in the rock of the castle, with apartments for 6oo men, and all rooms 

 of use, as kitchens, &c. This was done by the order of Marshal Boufflers, 

 to defend the garrison from the bombs, and was the labour of 4 years. At 

 Liege is Sir John Mandeville's tomb, whose epitaph is also at St. Albans with us, 

 which may be difficult to be reconciled. is; 



At Brussels I saw a young Friesland boy, of about 5 years old, round the 

 pupil of whose eye they pretend is naturally engraven Deus Mens, and the same 

 in Hebrew. This is considered as a prodigious miracle in those parts; but on 

 nicely surveying it I could perceive it was only the iris of the eye, not circularly 

 joined, but lasked out into fimbriae, which here and there might be thought to 

 form some imaginary letters, as beginning at the lacrymal corner of the left 

 eye, there is something like D, and I, and V, but not a trace for the strongest 

 fancy to work out any more, nor any letter of Hebrew in the right eye, as they 

 pretended. I do not doubt, but as the boy grows up, the others may conjoin 

 again. 



At the Hague there are very few natural curiosities, but there is a piece of 

 art, which of its kind I believe never was paralleled, which is performed by 

 one Elizabeth Pyberg, who cuts in paper not only towns, as Loo and Houn- 

 slerdyke, but faces to an extreme likeness; she has done King William and 

 Queen Mary better than any limner I ever saw, and refuses 1000 gilders for the 

 pieces; it is so curious that I could not believe the queen's drapery not to be 

 j)oint, till I had most carefully inquired into it. ;>
