moveable joints with each other, connected by ligamentous Btructurv 

 Underneath the cartilages there appear to be large hernial sacs opening 

 into each abdomen ; into which, on coughing, portions of the intestine 

 are propelled as far as the middle of the band ; though, in ordinary circum- 

 stances, these hernia are not apparent. The entire band is covered with 

 common integument; and when the boys face each other, its length at 

 the apex is one inch and three quarters, and at the lower edge not qwite 

 three inches Its breadth from above downwards is four inches, and its 

 greatest thickness nearly two inches. In the centre of the lower edge there 

 is a cicatrix of a single navel. It possesses little sensibility, and is of great 

 strength; for upon a rope being fastened to it, the twins may be pulled 

 along without occasioning pain ; and when one of them is lifted from the 

 ground, the other will hang by the band alone, without sensible inconveni- 

 ence. For the space of about half an inch from the medial line of the band, 

 the sensibility of the skin appears to be common to both. The following ex- 

 periment was tried upon them by Dr. Roget. A silver tea-spoon being 

 placed on the tongue of one twin, and a disk of zinc on the tongue of the other, 

 the moment of the metals were brought into contact, both the boys exclaim- 

 ed "Sow, sour :" thus proving that the galvanic influence passed from the 

 one to the other through the connecting band. Another simple but clever 

 experiment (which we need not detail, as all philosophical inquiries are not 

 fit for publication) proved that the sanguineous inter-communion was not 

 common to the two. 



Their strength and activity are very remarkable. They can throw down 

 with perfect ease a powerful man. They run with great swiftness, bend 

 their bodies in all directions, and in their sports often tumble head over heels 

 without the least difficulty or iuconvenience. In all the bodily actions in 

 which the concurrence of both is required, such as running, jumping, play- 

 ing at battledore and shuttlecock, they exhibit a wonderful consent, or 

 agreement, without the appearance of any previous communication of their 

 intentions. The intellectual powers of each are nearly equal ; and they have 

 both attained the same degree of proficiency in the games of chess, draughts, 

 and whist. They both possess great powers of imitation. In their respec- 

 tive physical constitutions, however, several differences are observable. 

 Chang, as the boy on the left is named, has more vigorous health, and 

 greater regularity of functions, than his brother, whose name is Eng. in ge- 

 neral they take their meals, and obey the calls of nature, at the same time. 

 The author details the circumstances "of a catarrhal complaint which attack- 

 ed both of them in December last, the symptoms and progress of which were 

 similar in each; and from which they both recovered in the same manner 

 and at the same time. In their healthy state their pulses are generally 

 alike, and are easily excited ; but that ot the one may he accelerated, while 

 that of his brother continues calm. 



In their habits they arc very cleanly and delicate; in their dispositions 

 affectionate and grateful for every kindness shown to them. There exists 

 between them the most perfect harmony. They always fall asleep at the 

 same moment; and it is impossible to wake the one without also waking the 

 other.— G. Bolton, Esq. Royal Society, London. 



ARTS, &C. 



,4 new Corn Mill is now exhibiting at 175, High Holborn, London, of 

 which much is said in commendation. The mill occupies a space but 5 ft . 

 square, and it is perfectly portable. It is propelled by a single horse, and 

 by one operation will grind and bolt 1 cwt. of grain per hour. The firsts, 

 seconds, pollard, and bran perfectly separated. The stones are formed 

 upon a new principle, of which the basis is the French Burr. 



The Wheels of Carts and Wagons have lately been much improved by 

 the introduction of cast-iron naves, or stocks. These stocks are found par- 

 ticularly suitable for warm climates, and I send a great many yearly to the 

 West Indies, and to other warm countries. I may notice to you, that tin 

 very first pair I nade of them, in July 1808, have been ever since in use | 

 the wooden parts, or spokes and fellies, were entirely removed about 

 eighteen months ago ; and the wheels are now, after the space, of twenty 

 years, nearly as good as ever they were.— Samuel Morton. Lcith M ti/li,
