### Oops

A doctor is going round the ward with a nurse and they come to the first bed where the chap is laying half dead.
"Did you give this man two tablets every eight hours?" asks the doctor.
"Oh, no," replies the nurse, "I gave him eight tablets every two hours!"
At the next bed the next patient also appears half dead.
"Nurse, did you give this man one tablet every twelve hours?"
"Oops, I gave him twelve tablets every one hour," replies the nurse.
Unfortunately at the next bed the patient is well and truly deceased, not an ounce of life. "Nurse," asks the doctor, "did you prick his boil?"
"OH MY GOODNESS!" replies the nurse.

### First milk quality law in U.S.

In 1856, the first milk quality law in the U.S. was signed by the Governor of Massachusetts prohibiting adulteration of milk. An individual had to take a complaint to court. With no official enforcement, the law was ineffective against “swill milk,” the poor, thin output of cows kept in sicky conditions and fed on distillery refuse. Unsafe milk was a public health hazard, sometimes deadly to infants. So the state passed a law on (6 Apr 1859) authorizing cities to appoint their own official Inspector of Milk. He was empowered to enter the premises of handlers of milk, and to take specimens for analysis, the results of which could be evidence used for prosecution. The law set ten dollar fines for selling swill milk. Boston was the first city in the U.S. to appoint a full-time Inspector of Milk, on 10 Aug 1859.«[Image: A New York City inspector at a grocery testing milk with a lactometer, c.1887.]
