108 ESSENTIALS OF VETERINARY LAW 
If no amount is stated in the receipt for services, 
it will be presumed that the charges will be rea- 
sonable. 
A form of receipt may be something as follows: 
Received from John Doe, 175 South street, Vin- 
cennes, a male fox terrier dog with brown right 
ear, (or, named ‘‘Gyp’’) for treatment and board, 
subject to the following rules and rates, to which 
it is understood that the owner agrees. Board, for 
dogs, $2.00 per week. Professional fee table on 
back of receipt. All bills to be paid before re- 
moval of the animals. Animals not paid for will 
be sold in 6 months. 
Vincennes, Ind. Signed, 
April 7, 1914. Peter Brown, 
Veterinarian. 
It is often advisable that other rules be given, 
such as that board must be paid at least every 
second month, and that the owner of the estab- 
lishment agrees to give ordinary care, but that 
he does not assume liability for unavoidable acci- 
dents, etc. 
81. Nature of a Lien. It is one of the essen- 
tials of a lien that it must bear some direct rela- 
tionship to the thing for which it is held. A horse 
taken to board could not be held on account of vet- 
erinary services for cattle on the farm. There may 
be some question as to whether an animal may be 
held for any old account. The English case of 
Scarfe v. Morgan ** seems to support such a claim. 
One Scarfe brought a mare to be served on Sunday 
by the stallion of Morgan. Morgan held the mare, 
354 M. & W. 270.
