attention being paid to each detail of the cleaning and disinfecting process, 

 whereas the smallest blunder may render the whole procedure useless. 



It will probably be a subject of enquiry what is the best course to be 

 pursued in instances when, from the construction of premises and other 

 circumstances, it would be absolutely impossible to carry into effect in their 

 entirety the means which have been recommended, and the answer can only 

 be in effect what is provided in orders relating to disinfecting and cleaning 

 processes, viz. that where the premises cannot be disinfected, as in the case 

 of a field, for example, in the manner directed, it shall suffice that they be 

 disinfected as far as practicable. 



27. OPERATIONS 



MEANS OF RESTRAINT 



Dealing with animals like the horse, of high nervous organization, great 

 strength and activity, and often considerable weight, it is sometimes 

 necessary to employ means of restraint whereby operations of greater or 



less severity may be per- 

 formed. Minor ones can 

 often be accomplished 

 under the restraining in- 

 fluence of the voice alone; 

 and in this connection it 

 may be remai'ked that it 

 is given to some men to 

 exercise great authority 

 over the brute kingdom, 

 while a want of tact and 

 judgment would seem to 

 preclude others from ever 

 attaining such a desirable 

 influence. 



Some of the means employed for this purpose are mechanical, others 

 physiological, and in their application may be confined to a limb, or to one 

 portion of the animal, or applied to his whole body. By superior force 

 the animal is rendered incapable of resistance, and the same may be 

 effected by the administration of drugs which overcome consciousness 

 and jjaralyse movement.
