UNPLEASANT DISCOVERY IN THE PATENT OFFICE--LEVYING BLACK MAIL.

"The Patent Office has been, during the past week, in a high state of

excitement, occasioned by the discovery of the operations of E. W. W.

Griffin, clerk in charge of the draftsmen's division, who, it appears,

has been levying black mail on the lady employes of the office, for

nearly two years. During the administration of Colonel Fisher, late

Commissioner of Patents, a large number of ladies were employed, for

the purpose of recopying drawings, when ordered by the inventors, of

patents already on file.

"These ladies were placed under charge of Griffin, with power to

retain them in office so long as their services were satisfactory. It

has been proved that Griffin hired the ladies at regular salaries of

$1,000 per annum, the most of whom he blackmailed to the amount of

$400 per year each. It is estimated that he has made $1,000 per month

for the past two years.

"The matter was brought to the notice of Commissioner Duncan, and an

investigation ordered, which resulted in the dismissal of Griffin.

"It is thought that there are other cases of this kind, and the

Commissioner expresses his determination to ferret them all out,

and make a clean sweep of all parties in his department engaged in

swindling operations, against the government or against individuals.

"The Patent Office has for a long time been considered a rich field

for operations of this kind, and investigations have often been

suggested, but passed unheeded by the proper authorities.

"It is openly stated that an investigation into the relations existing

between certain examiners of patents and certain patent agents, would

disclose a more fearful state of blackmailing than exists in all the

other government departments combined."

[We find the above sensational paragraph among the recent Washington

items of the _Evening Mail_. We are in a position to say that "the

high state of excitement" alluded to has existed only in the brain of

the newspaper correspondent. The facts, in brief, are these: In July,

1869, a lady, and wife of one of the clerks in the draftsmen's room,

made application to Commissioner Fisher for a position in the copying

division of the same department; and, upon the urgent solicitation and

recommendation of Mr. E. W. W. Griffin, chief of the division, she

was appointed, and has held the position from that time until now,

receiving as salary $1,000 per annum, which, with the full knowledge

of her husband, she has divided with Griffin, in consideration of his

services in procuring for her the appointment. About a month ago, one

of the lady's friends got hold of the matter, and reported it to the

Court, which resulted in an investigation and the subsequent dismissal

of Griffin. This is the only case of the kind that we have heard of,

and we have no reason to believe that there is any other, or that

corruption exists in the Examining Corps, as alleged.--EDS.

A method of testing the purity of samples of water, by watching

the rapidity of its action on soap and similar compounds, has been

introduced by the French _savants_, MM. Boutron and Boudet. The

experiment tests, at the same time, the purity of the soap. Dissolved

in water in which lime is held in solution, the soap is precipitated

in hard white flakes. If the quantity of soap put in the lime water

be noted, it will be found that the smaller the quantity producing

precipitation, the purer the soap. The _Journal de Pharmacie et de

Chemie_ (of Paris) reports some experiments, on this subject, by M. F.

Schulze.
