MEDICINAL TREATMENT 199: 
commencing dose about 6 minims thrice daily ; a Pekinese. 
would take 9 minims; a fox terrier, 12; an Airedale, 155 ; 
a collie, 18; and a St. Bernard, 20. ‘ 
After the first week the dose in each case may. oe 
slightly increased, and the medicine should be. continued 
for at least a month. Since Easton's Syrup contains 
strychnine (gr. 3: to each fluid drachm), which is a 
stimulant to the motor centres of the spinal cord, it 
will be readily appreciated how carefully the dose must 
be regulated, for full doses will produce tetanic con- 
vulsions, whilst small or medicinal doses are nerve tonics 
and antiparalysants, and their use is not indicated until 
the severe choreic spasms have abated somewhat. 
Arsenic has proved of considerable value in the treat- 
ment of chorea and epilepsy, for which in human beings 
it has been regarded as especially serviceable. Accord- 
ing to Finlay Dunn, its action in these cases appears to 
depend partly on its alterative properties and partly on 
its diminishing irritability of motor nerves. It should 
be given in full doses, well diluted, three times a day after 
meals, but the dose should be graduated from a small 
dose at the beginning to a full medicinal dose at a later 
period, for it is only in this way that an animal will be 
enabled to develop a tolerance of doses which, if ad- 
ministered at first, nvent ess fatal. 
‘Dogs will take gr. 3'5 to gr. 35, according to their size, 
or Fowler's Solution (which contains 1 grain in IIo 
minims) may be given in doses of mili. to mxil. a 
Sometimes it is desirable to cease its a diywinisteation 
after about a fortnight, especially when indigestion or 
diarrhoea becomes manifest, owing to its cumulative 
tendency; it may then be recommenced after seven or 
eight days, and during the interval some preparation of 
iron should be prescribed, particularly ferri redac., 
which is less liable to cause digestive derangements than
