are occurrence, these cases are comparatively common. I
have in mind one particular case of a servant girl, who, during the past
five or six years, has been employed in several families.

"In every family typhoid fever has later broken out. Experts have traced
out at least thirty, cases and several deaths due to this one person.
In another case we found an epidemic up in Harlem to be due to a typhoid
carrier on a remote farm in Connecticut. This carrier, innocently

The result was over fifty cases of typhoid here in this city.

"However, to return to the case of the servant I have mentioned. Last
spring we had her under surveillance, but as there was no law by which
we could restrain her permanently she is still at large. I think one

Shelter Island for the past season and that I have found her a reliable
servant and an excellent cook.

"Before God, Mr. Kennedy, I'm innocent," screeched Bridget. "Don't have
me arrested. I'm innocent. I'm innocent."

Craig gently, but firmly, forced her back into her chair.

Again the announcer snapped. This time the last page of Mr. Bisbee's
will appeared on the sheet, ending with his signature and the witnesses.

"I'm now going to show these two specimens of handwriting very greatly
enlarged," he said, as the stereopticon plates were shifted again.

"An author of many scientific works, Dr. Lindsay Johnson, of London,
has recently elaborated a new theory with regard to individuality in
handwriting. He maintains that in certain diseases a person's pulse
beats are individual, and that no one suffering from any such disease
can control, even for a brief space of time, the frequency
