On the Operation for Squinting. By Mr. A. Ure, of London. 
As a diversity of opinion prevails among surgeons as to the ultimate 
success of Professor Dieffenbach’s operation for the cure of strabismus, 
Mr. Ure was induced to lay before the Meeting the result of seventy- 
two cases (thirty-two males and forty females), in which the section of 
one or other of the muscles of the eye had been performed by himself. 
These were drawn up in a tabular form, including age, duration of the 
infirmity, cause, eye affected (right twenty-nine, left thirty-seven, both 
six), state of vision before operation, state of vision after, colours of 
iris (hazel twenty-eight, gray thirty-one, grayish blue two, blue ten), 
and result (cures sixty-six, of which nineteen are ‘ perfect,’ and twenty- 
one have fullness or other slight affection). In six cases the result was 
‘amendment.’ ‘The author described his process and after-treatment. 
A Description of a double Monocephalic Human Monster, which was 
transmitted to this country from South America, by K. Mackay, Esq., 
British Consul at Maracaibo, Venezuela. 
The subject of this paper was born at Maracaibo, Venezuela, South 
America, in the month of March 1840. It is the offspring of a negress, 
and is reported to have been born alive, but to have died a short time 
after its birth. It is of the female sex, and seems to be composed of 
two equally developed bodies united together from the umbilicus up- 
wards, bearing four arms and four legs, and having only one neck and 
head common to both. 
A minute account of the dissection was given, of which the following 
is a summary. 
The spinal and ganglionic nervous system were double, while the 
central was single, each corresponding with the organs which they were 
destined to supply. 
The organs of mastication and of deglutition were single, as were 
also those of digestion, with the exception of the inferior portion of the 
alimentary canal, which at a certain point became double. The re- 
spiratory organs were the least developed and the most anomalous in 
their character, there being two lungs situated in their usual position, 
and a third lung lying upon the posterior sternum, which seemed to be- 
long equally to both bodies. With the exception of the heart and the 
vessels which supplied the head, neck, and such organs as were single, 
there were two complete arterial and venous systems, which, with in- 
significant varieties, were disposed in the usual manner. 
The urinary and genital organs were double, and well developed.
