Abstract of a Registry kept in the Lying-in Hospital of Dublin. JBy 
Robert Collins, M.D ., late Master of that Institution. 
The numerous tables accompanying this communication were 
taken by Dr. Collins, with much care, from a registry kept by him 
of 16,414 deliveries occurring in the Dublin Lying-in Hospital in a 
period of seven years, commencing November 1826, during which 
he had the medical charge of the institution. 
The tables are placed in the following order: first, tables relating 
to all preternatural presentations met with in 16,414 deliveries; 
next, those relating to labours complicated with haemorrhage; re¬ 
tention of the placenta; convulsions; rupture of the uterus or va¬ 
gina ; with two or more children; or when the frenis umbilicalis 
descended before the child; and lastly, relating to the number of 
still-born children, and the number dying during the period of the 
mother’s residence in the hospital. 
The total number of preternatural presentations met with in the 
hospital during Dr. Collins’s residence as master was 409, (not in¬ 
cluding those occurring in twin cases,') or 1 in every 40. Of the 
409, 242 were breech presentations, 127 were cases of presentation 
of the feet, 40 of the arm or shoulder. 
Of cases of haemorrhage, 11 were unavoidable; 13 were acci¬ 
dental ; 64 occurred between the birth of the child and the expul¬ 
sion of the after-birth; 43 were subsequent to expulsion of the pla¬ 
centa. 
Sixty-six cases of retention of the placenta occurred; 30 cases of 
convulsions; 34 eases of rupture of uterus or vagina; 240 women 
were delivered of twins. Of the 480 children, 422 were born alive ; 
245 were males; 309 presented’naturally; 73 with the breech; 60 
with the feet; 7 with the arm or shoulder. 
There were 97 cases of prolapsus of the umbilical chord. 
Of 16,654 children, 1,121 were still-born: 527 of these were 
putrid; 614 were males. 
Of 16,654 children born, 214 died previous to the mother leaving 
the hospital (generally on the 8th or 9th day after delivery). 
All the results above stated are further analysed with reference to 
the age of the mother; first, second, &c. time of pregnancy; length of 
time in labour, and other circumstances important to medical science. 
It has been found impracticable to abstract the numerous and de¬ 
tailed tables and deductions contained in this valuable registry, so 
as to do justice to the author’s views, without occupying many pages. 
Dr. Collins refers on some points to his 4 Practical Treatise on Mid¬ 
wifery.’
