EXTRACTION OF A LAMB— HEAD AND ONE FORE 
LEG PRESENTING. 
By the same. 
On the 24th March, 1847, an aged ewe, belonging to William 
Halstead Poole, Esq., or Terrick Hall, began to yean by presenting 
only the head, which was entirely protruded through the vagina. 
I was sent for. 
Method of extraction . — I tried to pass my hand up by the side 
of the neck of the lamb, so as to bring the feet forward ; but this 
I found quite impossible from the smallness of the passage. 
I then pushed the head and neck into the uterus, and, after a 
good deal of trouble, I brought one of the fore legs into its natural 
position. All my efforts were unavailing to get the oth$r leg into 
its place without killing the lamb. I now tried to remove the 
lamb by pulling at the head and one fore leg, and by a little force 
I succeeded. The ewe and lamb did well.

OBSERVATIONS ON THE AGE OF THE OX. 
By M. Eug. Renault. 
[From the “ Recueil de Medicine V4t6rinaire.”] 
Few farmers, not many veterinarians, probably have sufficiently 
thought on the influence which breed, early weaning, and food, 
both as respects its nature and quantity, exert on the dentition of 
domestic animals. Nevertheless, this is a subject no less worthy 
of attention, from its being a phenomenon full of interest in a phy- 
siological point of view, than as casting important light on the 
order or regularity with which the temporary teeth make their 
appearance, come into use, and are replaced by the permanent; 
and as shewing to what extent the latter may be regarded as 
faithful and unerring signs of age up to a certain period of the 
animal’s life.
