10 ESSENTIALS OF VETERINARY LAW 
unconstitutional.® Similarly, regulations as to 
manufacture were considered to be legislation, and 
so not law.!° But regulations relative to marking 
of goods were considered true regulations, and not 
additional legislation.1! ‘‘As regulations depend 
upon a statute, they can never go to the extent 
of being independent of the statute. A regula- 
tion which is in effect legislation is in a just sense 
a regulation no longer. That is, as a regulation is 
derivative, it must keep within the scope of the 
statute under which it is formed.’’ ” 
This point is very important for veterinarians 
for two reasons. First, many members of the pro- 
fession hold administrative positions, and as such 
it is their duty to apply the laws enacted. Through 
mistaken ideas of their authority they often at- 
tempt this excess of power, and if they do so to 
the injury of any one, they may be held lable for 
such damages as may appear. Secondly, veterina- 
rians are working under the law, and they may be 
met with attempts at illegal use of official posi- 
tions in a way that may work injury to themselves 
or to their clients. If, in such cases they know the 
general principles of the legal situation, they may 
save themselves and their clients trouble and 
money.*?
