My chemical reagent case being at my ,, in White county, where the geological .. ''l is now progressing, have not been an 9 this occasion, to make thorough tes. <, 0 constituents of the hot springs; but h.. @s piled such-as I could obtain in Dr. Ham,. P office, at the Hot Springs, and find the f,n ing ingredients: Carbonic acid, Lime. Magnesia, and , k. by Alumina, also Silica, Chlorides: n,'l Ebe both of Soda and Potash tp. Judging from the curative properties ofa waters, expect to find il them, hcntb.n to be thoroughly analysed, carbonate of D, and Soda; as we'll as Iodides and Bron3. these bases, since, in most cases o.,I sweelinss and visceral Instructions ssa,. removed aud reduced by the use If ' waters. To detect these springs it is L always necessary first to concentrate tb.
 by boiling down large quantities of tb. before the chemical reactions of tbesa on, l ces can be brought out.

 Experience has fully demonstrated the val n ble remedial properties of the Hot Sprr, 4. Arkansas, especially in chronic diseases !; cutaneous disorders, certain chronic form, N rheumatism, gout, neuralgia, mercurial N, Al plaints and visceral obstructions, they ,,, oH culiarly applicable and often effect remat. pr cures even in short space of time. N, cases which have refused to yield to the adm tration of medicine by the most expersp {, and skillful physicians have been either ga. mittigated or entirely cured by the useoI5. waters. Invalids from all parts of the Ur, and even Europe, have resorted to these 6 Springs with the happiest effects on their he, ? spirits and cons,itulion ard from the great VI 4 ty in the temperature of the different s., Il they are applicable to every case where !s t' mai waters are indicated.
 The magnificent crystalizatious Of lin quartz found both in Hot Spring and Moa. mery counties and elsewhere in this pas :, Arkansas, are either obtained from cavities crevices in hard quartzose sandstone sts usually in the lower part of the ridge, q above described quartzose formation oyerr the sIates or in the red clay and loose debs N the foot of their slopes. They have evidsr been formed by the percolation of waters h ing silica in solution into the cavities and ns '. stices of the sandstone. S.lex is often dss Ii ed by thermal waters, especially those impa pl mated with alkaline carbonates.
 When such waters have an opportunir 2, depositing their mineral contents slowly rt without disturbance, the silex will be depos atom by atom so as to assume the resl .s mathematical solid peculiar to this bemt n mineral This law applies indeed to all pap mineral substances of definite chemical conD sition; each mineral when passing from liquid to the solid state will arrange its pa,ta X in conformity with the plans of the mathsa s tical nucleus appertaining to it, on and anuv which they well seggrega;e in decran'- e either co-inc;dent with the planes of the Gs n nal prim 'tive nucleus, or pass into secoIirs $ derivative forms often complicated but alEgt dessectable back to the primitive form.

 On Mondly the 7th inst, I proceed to N, my corps now occupied in making geooss' reconnaissance of some of the counties souh | White river. From White county propoa pass into Van Buren, thence into Searcy NH ton, Carroll, Madison, Benton and Washing to the western confines of the State. U corps will then pass into Crawford, and rsiH through the counties bordering north ola Arkansas river; viz: Franklin, Johnson, F'P Conway, Puluski and Prairie, to the westernp of Monroe county.
 The inhabitants of these counties whode information in regard to minerals Iound ID IS neighborhood would do well, in the meangl to collect specimens of the same, as 1t wills much of the valuable time of the geobs corps, if, before visiting the localities, they @~ have samples laid before them; since by lr'is I ton the geologist may often be able to g'sh the desired information and judge from knowledge of the value of the mineral ol necessity or advantage of deviatiug from route to examine the locality.
 By the time the corps reaches Monroe COZ ty IL will be necessary that the masHaS lected be as soon as possible worked upN office, in order that the manuscript reponS S1 he prepared and go into the printers hanaA n Il a..
