'20S GIZZARD OF fowls: 



Experiments on B. The aqueous decodlion took a light yellow tint, aed 

 gizzar . fpjgiig^ Ijj^g chicken broth. 



It reddened the tindure of turnfol. 



C. Lime-water and water of baryte? caufed tlie fame kind 

 of precipitate as in the deco<5iion of IVeth gizzard. 



D. Oxalate of ammonia proved the prefence of lime. 



E. Oxigenated muriatic acid feparated white flakes. 



F. Nitric acid had a violent cfFeft upon the dry gizzard; 

 at a mild temperature it diffolved it completely. 



Nitric acid at eighteen degrees excited a flight effer- 

 vefcence, and by gradually increafing its temperature, a fepa-% 

 r'ation was perceived of azotic gas, then of nitrous gas, and of 

 carbonic acid gas. 



The liquor left in the retort was evaporated, in the ex- 

 pedation of obtaining cryftals; but on cooling, none ap- 

 peared. The evaporation was then continued, the refult of 

 which was a yellowifli glutinous matter, tenacious, and of an 

 exceffively bitter and acrid tafle. 



Water imbibed the acid, and prefented all the characters 

 of the decoction of apples, 



G. Metallic folutions prefented nothing particular, as In thcc- 

 cxperiments upon frefli gizzard, except that antiraonial tartrite 

 of potatli wa^ decompofed, forming in the decoftion a white 

 precipitate, 



H. Aqueous infufion of nut-gall produced a lefs copious 

 precipitate in this experiment, than it had with that upon 

 frefti gizzard. 



I. Dry and friable gizzard was digeSed in alcohol ; but the 

 liquor was fcarcely coloured, even with the affiftance of 

 caloric. 



This alcoholic tinfture reddened that of turnfol, and gave 

 precipitates with lime-water and water of barytes, as alfo 

 with nitrate of filvcr; a proof that the alcohol has diflblved 

 only die faline particles. 



L. The incineration of gizzard left a reGdue of a faline and 

 alcaline tafte. Paper tinged by curcuma became of a deep 

 brown. 



This refidue was partly foluble in water. The liquor con- 

 tained fulphate, muriate, and carbonate of potafli. 



The part not foluble, on being fubmitted to the aflion of 

 muriatic acid, difcovered carbonate of liaie, phofphate of 

 lime, and a fmall portion of Iron.
