532 PHILOSOPHICAL TRANSACTIONS. [anNO I67O. 



the probe, but doubting a failure in that experiment, we made an essay with a 

 blow pipe, and thereby we found, that the wind would go no further than 

 the place above-mentioned. Whence it may be concluded, that the right- 

 handed child must have received its nourishment by and from the left 

 child. 



There was but one colon or colic gut, which terminated in two intestina 

 recta. So there was but one midriff, and above that we could find little or no 

 appearance of lungs ; but only a very large heart, with two auricles, the figure 

 of which was not conical, but like a soldier's pera or knapsack, or the ventricle 

 or stomach ; and lying near under the clavicles, transverse as the stomach lies 

 under the midriff and liver. We also observed two ventricles, with the tri- 

 cuspid and sigmoid valves ; as also the vena cava and aorta dependant, [de- 

 scending] and also the aorta ascending and bifurcate towards each neck, and 

 then bifurcate again. 



These twins were exactly like one another ; very well featured, having also 

 pretty neat and handsome limbs. They had their hair more than ordinarily 

 thick, and about half an inch long, and the nails full grown. 



Ohsei^vations on Insects lodging themselves in Old JVillows. Produced 

 before the Royal Society, by Dr. Edmund King, July 14, I67O. 

 N' 65, p. 2098. 



About the beginning of May last, a piece of old willow wood being sent me 

 from Sir John Barnhard from Northamptonshire, was produced before the 

 Society, in which were lodged many insects curiously wrapt up in green leaves, 

 in several channels or burrows, each with 12, 14, or 16 leaves round the body, 

 and several of them with as many little round bits of leaves at each end, to stop 

 them up close. These, thus made up, are near an inch long, put one after 

 another into a bore made in the wood, fit for their reception. They are in the 

 manner of cartridges of powder, wherewith pistols are wont to be charged, or 

 like long slugs of lead, as are sometimes used in some parts of those burrows ; 

 they are placed so near one another as to touch ; in others at some consider- 

 able distance. These insects observe this method in placing themselves, that 

 sometimes they make a direct way into the length of the wood, sometimes 

 they bore out into the side, and run another way, those channels being not 

 unlike the burrows of rabbits ; all which they fill up with these round appear- 

 ances of wrapt leaves, all regularly wrought : In which I find either something 

 alive, or appearances of something that has died there and is putrified : In 

 some a great number of mites, of a dark ash colour, shaped not unlike com-
