Lockjaw (tetanus). — This is a specific 

 disease, being caused by living germs, 

 each germ having the shape of a screw-eye. 



These germs are constantly present in 

 the soil of certain localities. A trivial 

 wound, such as a sore back, saddle or 

 collar gall, puncture of the foot, &c., is 

 quite as liable to be followed by the 

 appearance of lockjaw as when the wound 

 is deep or extensive. 



At the best of times lockjaw is of grave 

 moment, and a large number of deaths 

 arise through it. Eecoveries are not un- 

 common. 



As no amateur would be likely to 

 undertake the treatment of a case of this 

 description, we consider it inadvisable to 

 enter into a discussion of the symptoms 

 and treatment. 



One very important matter to bear in 

 mind is that of preserving the most 

 perfect quietude. Noises of every descrip- 

 tion aggravate this malady. Even the 

 careless opening of the stable-door will 

 bring on a spasm. 



Loins, strain of. — Heavy draught- 

 horses are those most liable to suffer 

 injury in the region of the loins. A 

 heavy weight falling on the back, or a 

 heavy load, up or down hill, are both 

 capalDle of producing strained muscles in 

 this region. 



The horse must have several months' 

 rest, and the spine should be massaged 

 daily.
