MR. BOLTON ON THE UNITED SIAMESE TWINS. 
dressing. They are exceedingly affectionate and docile, and grateful for 
every kindness shown them. It is not often that they converse with each 
other, although their dispositions and tempers agree, and their tastes and 
opinions are similar. Sometimes they engage in distinct conversations with 
different persons at the same time, upon totally dissimilar subjects. Both 
are very fond of music, and are equally interested in dramatic performances. 
It does not appear that they have ever had any serious quarrel, except on 
one occasion, which occurred, as their mother reported, when they were eight 
years of age. While on their passage to America, one of them wished to 
bathe, as was their custom, to which the other objected, the day being cold ; a 
slight dissension ensued, but Captain Coffin soon reconciled the difference. 
They always fall asleep at the same moment, and it is impossible to wake 
one without also arousing the other. When they were at Boston, Doctor Skey, 
Surgeon General to the British Army, entered their bed-room at midnight on 
three successive nights when both were asleep : on each occasion he touched 
one and was answered by the other, both awaking at the same instant, inqui- 
ring why they were disturbed. 
The experiment has also been repeated in this country, and with the same 
result. On my tickling one of them, the other told me to desist, though he 
stated that he did not feel the touch, and it was quite clear that he could not 
see me tickle his brother. 
On their voyage to England one of them had the tooth-ache, during three 
days and nights, and suffered great pain, with loss of sleep, which last evil 
was shared by his brother, both remaining awake. On the 16 th of December 
Mr. Hale went into their bed-room when they were asleep. Eng was restless, 
and tossing about in bed, while Chang was screaming. He awoke them, and 
on inquiring what ailed them, Eng replied that he was dreaming about his 
mother, and Chang said that a man was cutting off the long hair from his 
head. These different dreams appear to have occurred simultaneously. 
The preceding instances of their mutual consent in many physical and 
moral particulars, may be accounted for by their constant moral and physical 
intimacy, which unquestionably is the source of more impressions common to 
both, than ever happen to two distinct individuals. They are at present very 
much attached to each other, but judging from what is now become a very
