FRACTURE OF THE SUPERIOR MAXILLARY BONE. 217 
present it will suffice if we at once give place to what we have 
become acquainted with during the past month, adding a 
few comments thereunto, by way of elucidation or extension. 
POISONING BY NITRATE OF POTASH. 
Mr. J. C. Truckle has informed us of two cows out of 
three having died within three hours, and that, apparently, 
without a struggle, after taking a third part of a pound of 
nitrate of potash, and half a pound of sulphur, mixed together. 
The post mortem examination showed that the third and fourth 
stomachs were inflamed, more especially the latter. 
The bovine tribe would appear to be easily poisoned by 
this salt. We were consulted some years since respecting 
the causes of the deaths of several cows, and on inquiry 
ascertained that the owner of the animals had been giving to 
each half a pound dose of American saltpetre (nitrate of soda) 
which he had bought as a cheap purgative ! We also re- 
member three cows and two heifers, belonging to a gentleman 
in Suffolk, being poisoned by taking three-quarters of a pound 
of nitre each. All the animals died within twelve hours. 
The agent had been sold by a grocer in mistake for sulphate 
of magnesia. 
FRACTURE OF THE SUPERIOR MAXILLARY BONE OF A DOG. 
Mr. Dods, of Kirkcaldy, writes us that he was lately con- 
sulted about a bull dog which had sustained a fracture of the 
superior maxilla, extending quite across the jaw, about an 
inch and half behind the incisor teeth. He had first a firm 
linen bandage applied around the jaw, in which holes were 
made to receive the tushes, and prevent the displacement of the 
compress. Over this, and embracing both jaws, another ban- 
dage was placed so as to keep the mouth closed. The animal 
took freely of meat broths, and in about six weeks not only 
had union taken place, but so perfect was it that he was again 
employed by his owner, a butcher, to assist in getting 
bullocks into his slaughter-house. Mr. Dods also says that 
he has met with analogous fractures in colts, which, by 
adopting a similar plan of bandaging, have gone on to his 
perfect satisfaction.
