tinnes in that same state diiiiii.?; tlic whole process of crystallization. It may be called 

 erystaUizable matter. 4ilily, Tiiiti cryslnlliznblt matter is that which has filled, by infiU 

 tration, the chasms and clcfrs of mountains, and Xhn cavities of rocks; which composes 

 the veins, the stalactites, and the stalagmites; and, in general, all that which constitutes 

 accidental formations fonnd in blocks, nodules, &C. within large masses." 



He recommeiuis for his cryslallo'rpnons process, " a bed one inch thick, composed of 

 loose earth, obtained from the decompositinn of the stone in which the erystaUizable 

 matter is found, having an elevaicd brim of the same material round it, one third of an 

 inch in heisht. Some balls made of (lie sanif earth are disposed here and there on thi* 

 bed, on which aie placed various i)iect's of solid erystaUizable matter, formerly known 

 under the name of crystalline mutrir. On these pieces other balls ate properly disposed, 

 nerving to support some more specimens of crystallizable nuifter, so arran,'»ed as not to 

 touch each other. The whole of it is then made, as solid as possible, by the addition of 

 other lariii' and small balN, introduced win rever any space exists ; and lastly, the appa- 

 ratus is surrounded by a v.ali of bricks laid singly on each other, without any nioitar, 

 and in a way to admit a free circulation of air. 



Every two or three days the whole apparatus is watered, so as tol<eep it in a state 

 of constant humidity, and no more. A degree of temperature is maintained equal to the 

 internal temperature of the earth; and (he afiparalns is examined every fortnight or 

 three weeks ; when, if necessary, the pieces may be carefully washed and replaced, 

 takini; care to arrange them so that the balls, which before were under, may now be 

 placed above. After a ceiiain lapse of time, the ciystallizable niattei is found to pre* 

 sent distmct and beaulifiil crystal of the substances employed. 



MONTHLY REPORT OF DISEASES in N. W, LONDON; 



From Jiili^ 24 to Avgust 24, 1816. 



T'\THUS has much dir>iinished in frequency. Scarlatina disappeared in my practice 

 about the 5th of the present month, since which, disorders of a highly inflammatory 

 natnre have appeared. Several cases of anomalous disease of this kind have occurred, 

 where the inllammatorj' diathesis was so stroni; as to require unusual depletion before 

 it could be subdued. One patient was attacked with symptoms of apparent inflain- 

 matiun of the bowels, from which (he disease shifted to the icgion of (he liver, thence 

 to the chest, and finally settled in the head and face, which became intensely painful 

 and sore to the touch. I considered this to be a violent ilieuniatic atJf'ection, not without 

 dancer, from the frequent metastases which occurred ; and the treatment, which hap- 

 pily proved successful, was founded on that principle. Bleeding, to a large extent, 

 •with the internal exhibition of nitrate of pot-a'^h, ipecacnan, and opium, were the prin- 

 cipal remedies. Some cases of sciatica, of long standing, have been cured by the same 

 plan ; as this disease is not generally supposed to be inflammatory, the fact deserve* 

 to be held in remembrance ; and, where it resists the usual means, bleeding, local or 

 general, should be tried, uidess some contra-indication exist. In ordinary cases, it may 

 be sulfieient to give a few graius of calomel, with opium, every night, and a dose of 

 purging salts the following morning : occasionally, the internal nse of oil of turpentine 

 may be had recourse to at the same time, with advantane. It may be given in tloses of 

 from Uiirty drops to two drams, in honey, two or three times a-day. 



An obstinate painful affection of thehip and legs was cured by the follovtinp liniment 

 -—Oil of rosemary and sweet oil, of each an onnee; camphor, two drams; oil of turpen- 

 tine, half an onnce. The disease had existe<l three years, and was subdued by the re- 

 medy in less than the same number of days, John Want.

MONTHLY COMMERCIAL REPORT. 



T'HE Manufacturers of London and its vicinity, sensible of the imminent dangers witli
