American Discovery.
we announced sometime ago, the extraorjinnl
discovery made by Mr.. r. A. Tighlrnon, "ef "A
accompanying porer of sa1tsr at high temperatures
We then referred 10 the immense value Of this ii,
eovery in restoring the refuse lime of gas mani
:actoTies, and the refuse phsie of lime OF iaIs
soap establishments 10 their primitive qualities
through The discoveries of Mr.. Tighlman, and W
promised further account of the results and cha
acter of MIR. Tighlmsn's ingenious lab re. Tn
great discoveries in Ireland, in regard TO Irish Pea
have caused much excitement and Joy in England
and Lord Aberdeen YVES almost justified In the Z,
clsration, that the discovery equal to the Cal
ifornia Developments. Mr. Tighlmln's discove
ries are scarcely less valuable TO this country 70
the development OF wealth, and We have NJ
doubt that they are the basis of the discovery 0
the properties of Irish Peat.
Ills great thing to guide properly and success
FULLY public blessing, and Dean Swift declared
That the man who made two blades of grass grow
where only one had previously grown, was entitled
10 more honor than all the statesmen of the coun
ny, and we feel that NJ. Tishman's disco erie.
connect him closely with both Of these elements
OF greatness. In Ireland a miae Of wealth has
been discovered in Irish pest,-in America, Mr.
| righ'msn has discovered one vastly more extern
sve in The paving stones on which we walk and
ride.
When Mr.. Tighlman visited England for the pur,
pose OF taking out his patents, he waited upon
"Prof Solly, of LONDON, for his professional opinion
in reference to his discoveries, and their sppica.
ton 10 he arts, and received in answer that they
were perfectly new TO him, unknown in Europe,
and were fairly the biecs of patents. Also that
the objects are Of great Importance, likely TO
lead 10 many profitable Improvements in our ex-
Istins manufactures, as well as probably create q
number Of new ones. He Acknowledges that the
results communicated by Mr.. Tighlmar depended
on new and hitherto unnoiced law Of Chemistry,
the probable future influence of which can hardly
at present be estimste1."
Through the discovery OF "lLe dee1mposins
power OF water al high temperatures" Mr.. Tighl.
man is able to take Jsispar and decompose il in.
10 alumna and potash, and 10 make from that CON-
mon and, heretofore, useless material such
salts of potash, the sIlphse, chloride and chro-
mate. Through the same discovery, Mr.. Tighl
man has made great Improvements in the manufac.
iure OF certain acids, slkalis, aud alkaline salts,
and they are destined 10 have a great influence on
the general welfare. I.ieOig looked TO ne nation
al consumption Of soap in order 10 make proper
estimate Of national prosperity, and aB soda ash
has much TO DO with the manufacture of soap,
whatever tends 10 increase its production at d.
unfinished cost, must have much to do with the
general good.
The experiments Of Mr. Tishlman, according TO
the J'uTr1! Of Pharmacy, show thst soda can be
made, By the ton, at less than one half the con.
consumption Of fuel aud cost Of labor over the
old method.
Ne better evidence OF the merit Of Mr.. Tishl-
mans discoveWneej be sought than is found in
the fact that Mr. Tenant, Of Glasgow, the greatest
manufacturer of soda ash and potash IN the world
has msde an expenditure Of between twenty and
thirty thousand doiIars in fitting up apparatus &C.
cord.ns to the plans Of Mt. Tighlman. Notwith-
standing the immense machinery already AT work
in Mr. Tenants establishment, Tighlman's was
so far superior that ule privilege o. using il was
at once purchased BY MIR. Tenant.
The Jovrnai of Pharmacy says: alt is estab-
lshed that there are seventy thousand tons OF soda
ash made in Great Britain annually, valued al
forty.hve dollars pet ton, and equal TO three mill
ion one hundred and fifty Thousand dollars. The
twin alksli, potash, iieIiensiyey used. Russia,
Canada, ard New York alone export potash, esti.
mated at two and half millions of dollars, and
when IL is considered that Mr.. Tghlman is able to
manufacture not only these, but suIphuric acid
and many other highly usefdl artiolee, from com
moa rocks, extensively spread over this continent,
some idea may be formed of the exceeding value
Of his great discovery. 10 1888 sulphuIic acid,
valued at FIVE millions Of dollars, WAS manulac
inred in Great Britain, ard Mr.. Tighlman can OBJ
tain il from the same kind OF sources he gets his
material for making soda and potash.
Mr. Tighlman han conferred no ordinary boon on
his country by his discovery. We regard It as one
Of he highest benefits that science has contribu.
ted TO the general welfare, and the discovery
was the result Of thorough acquaintance with
chemistry. All honor 20 the man, who has con,ri-
buted so largely to the public good and national
prosperity-who ms made quarry more valuable
than gold mine.
