THE BOVINE FOKMULARY. 685 



side in the case of dangerous drugs, it is always best to use the 

 mildest preparations. We need not caution the skilled reader 

 on such a point, but we may just say for the benefit of those 

 who are not conversant with the technical names of preparations, 

 that no one ought to prescribe without the aid of a Pharmacopoeia 

 by his side for reference. A British Pharmacopoeia, or our 

 Veterinary one will be found very useful. Even mistakes have 

 arisen owing to persons making the error of thinking that spirit 

 of chloroform is the same preparation as is chloroform itself, 

 and other misapprehensions may assail the unpractised man, 

 when he first begins to prescribe. Errors such as these could 

 not possibly arise, if due care were taken. There is no science 

 which requires greater judgment, care, and accuracy than that 

 of prescribing for the numerous maladies to which animals are 

 liable, except, indeed, that of human medicine, in which any 

 mistake is fatal to the practitioner, and quite inexcusable and 

 culpable. We may add that this Index is in some measure 

 amplified by notes supplied by Mr. J. B. Gresswell, F.R.C.V.S., 

 whose eminent position as a practising veterinary surgeon is 

 well known and recognised. 



ACTINOMYCOSIS, 

 (a.) Local treatment. 

 (i.) Mixtxire — 



Iodine, one part. 



Carbolic acid, four fluid parts. 



Glycerine, four fluid parts. 



After the affected part of the tongue has been carefully incised, this mixture 

 may be applied by means of a brush to the sides of the indurated tumoura 

 which are present in the substance of the tongue. In the place of this mixture, 

 simple tincture of iodine may be used, or it may be diluted, if it be thought 

 necessary so to do, by adding to it an equal portion of spirit (methylated or 

 otherwise). The tincture thus diluted is very useful for applying to the diseased 

 parts of the tongue when that organ is sore and eroded. 



(ii.) Gargle — 



Acid solution of nitrate of mercury, eight minims. 

 Water, one ounce. 

 This gargle may be used for washing over the diseased tongue as an appli- 

 cation, after the tumours have been cut into. 



(6.) Internal treatment. 



Draughts or powders known as Tonics may be beneficially administered when 

 there is loss of appetite or emaciation, and they may be given once daily, or less, 

 frequently according to directions, and as may be deemed advisable.
