sufiBce ; but if not, after trying good noiirishing animal food, 

 mixed witli a proper proportion of vegetables, recourse may be

 Extract of gentian, 3 grains. 



Mix, and form a bolus. To be given three times a day. 



Attention must be carefully paid to the state of the bowels, 

 both constipation and looseness being prejudicial to the health, and 

 each requiring the appropriate treatment laid down at pages 412 

 and 414. Sometimes the tonic pill (62) will do wonders, and often 

 the change from it to the sulphate of zinc and back again will be 

 of more service than either of them continued by itself. A perse- 

 verance in these methods, with the aid of the shower-bath, used

 followed by moderate exercise, "will sometimes entirely remove the
