FGETAL DYSTOKIA DUE TO HYDROCEPHALUS. 
By J. H. Honan, Y. S., Delphi, Ind. 
On April 23d last, at 5 P.M., I was called thirteen miles 
ito the country to attend a case of difficult parturition*. On 
rriving at my destination I found a large brown mare, eight 
ears old. While changing my costume for the work I 
learned that the mare had been trying to foal since about 
oon of the day before, and that morning the owner had sent 
>r an empiric in the neighborhood, who had exhausted all 
is strength and ingenuity to effect delivery, as did all the 
eighbors who were accessible, but without result. 1 made 
n examination and found a dorso-sacral presentation, with 
ase turned forward, the occipital crest being the first part 
f the head felt. After careful manipulation I soon learned I 
ad a case of hydrocephalus to deal with. I therefore took 
ty embryotome and excised the head at the occipito-atloid 
'ticulation. After drawing off the water, which I did by 
le use of the trocar and canula, 1 succeeded in getting the 
sad, after which the bod} 7 was easily delivered. 
1 brought the head to my office and cleaned off all the soft 
ssue, and now have the dry bony specimen, which measures 
; follows: Circumference of cranial cavity, 26 inches ; diam- 
er in medial line, 9 inches ; diameter across between the 
yo frontal bones, 6 inches. This space was covered by a 
orous membrane under the skin, which was greatly dis- 
jnded, having about two gallons of a yellowish water, which 
ndered it almost impossible to effect delivery until this fluid 
as drawn off. Aside from the above abnormality, all other 
Arts were perfect.
