We have already described the proportions to he used in 

 making the ointment, and the doses to be administered. 



We may now pass to the consideration of certain diseases 

 immediately connected with the nervous system, irrespective 

 of acute inflammation of the brain, or of any of the viscera of 

 the chest or the abdomen. We mean those diseases in which 

 the nerves of some part, or the nervous system generally, are 

 immediately disturbed, irritated, or paralysed, and to the 

 affections of which the leading symptoms have direct and ex- 

 press reference. Hence are these diseases called " nervous," 

 not that there is no disturbance of any other part of the 

 frame ; quite the contrary, but because the nerves bear the 

 brunt, as it were, of the attack. 



PALSY, OK PARALYSIS. 



This disease, which bears among farmers and cow-leeches 

 the ridiculous names of joint-yellows, tail-rot, tail-ill, or tail- 

 slip, is by no means an unfrequent disease, especially in low 

 marshy situations, and during a cold and changeable spring. 

 Scanty food, bad water, damp, ill-ventilated, arid filthy cow- 

 houses, also conduce to it. Overworked cattle turned out 

 into humid pastures, during a cold sleety night, perhaps 

 while sweating profusely, and with no shed to protect them, 

 are very liable to palsy. 



Palsy in cattle is generally confined to the hinder quar- 

 ters, and both sides are alike affected. 



Sometimes the attack is sudden, but in most cases it comes 

 on gradually. It begins with debility, and a trembling or 

 failing of the hind limbs ; the appetite is now impaired or 

 suspended, and the animal staggers as it walks : soon the 

 hind limbs drag along feebly, and with difficulty perform 

 their office ; the pastern joint is bent to the ground, and the 

 animal is supported upon it ; the other joints of the limbs 

 give way in turn, and the animal sinks down upon the ground. 



It occasionally happens that cows left well, or apparently 

 so, in the pastures, at the close of day, will be found chilled 

 and palsied in the morning ; the attack has been sudden, but 

 it may be weeks before the animals are restored, and some 

 perhaps will never recover. 



With respect to the treatment of this species of palsy, 

 bleeding will be serviceable in the first instance, followed by 

 warm cordial purgatives, in each dose of which there may be 

 an ounce of ginger, and half a pint of good ale. The bowels
