GOVERNMENTAL INSPECTION 203

 under governmental supervision, and subjected 

 to careful scinitiny. 



If a governmental inspector or supervisor, either 

 through unworthy motives, and incentives, or be- 

 cause of carelessness, shall be shown to be negli- 

 gent in the matter, and permit practices in connec-

 employee may be personally liable for the harm 

 resulting; but the holding of such officer by no 

 means reduces the responsibility of the manufac- 

 turer. He may still be i^rosecuted criminally and 

 civilly. It may be that the damages may be as- 

 sessed against the manufacturer and the negli- 

 gent official conjointly.

 has occuiTed, the duty of ferreting out the evi- 

 dence may, and probably would, devolve largely 

 upon veterinarians. First, it should be detected in 

 those used for the manufacture, either before or 

 after slaughter. Secondly, should it not be de- 

 tected at the start it must frequently be traced 

 among the subjects upon which the product is 

 used. This, in a large proportion of the cases, will 

 be among the lower animals treated by veterinar- 

 ians. In these cases, the work of the official veteri- 

 narians would be greatly facilitated by certain pos- 

 sible records made by private practitioners. 



Where, as in protection against hog cholera, a 

 large amount of serum is used, the veterinarian 

 should make such a record that he can trace the 

 serum used on any particular lot. This is required
