396 PHILOSOPHICAL TRANSACTIONS. [aNNO 1794. 



incrustaticn, which in taste and appearance was very similar to what I have just 

 now mentioned. Of this I dissolved a part in water, filtered and evaporated the 

 solution, and thus obtained a true soda, or inineral alkali (natrum), which shot 

 into very neat and regular crystals. 



For the sake of comparison, I examined another large mummy in the Mu- 

 seum which had already been opened in several places. This was of a full growa 

 person, and measured 5 feet 5 inches in length. Like the former, it showed not 

 the least trace of any of the soft parts, but consisted of nothing but naked bones. 

 Except a little rosin which stuck fast between the teeth, this mummy, as far as 

 its inside could be examined, contained none of that substance ; its thoracic and 

 abdominal cavities being entirely filled with a dark brown mould, which also oc- 

 cupied the whole space between the palate and the lower jaw, where it could 

 easily be loosened and drawn out with the fingers. The maxillae of this mummy 

 were still less prominent than those of the former one. 



Some weeks after, viz. March 17, I had an opportunity to examine one more 

 mummy at the Hon. Charles Greville's, f. r. s., which had 4 years before, viz, 

 March 29, 1788, been already opened in the presence of several curious specta- 

 tors. It belonged to John Symmons, Esq. of Grosvenor-house, Westminster, 

 who with the most obliging readiness allowed me unconditionally, not only to 

 dissect it as much more as I should think proper, but also to select and take 

 away whatever parts of it I should think worthy of a particular investigation. 

 It was a mummy of a child about 6 years old, which as to its preparation, (viz. 

 without rosin, and without the least remaining trace of any of the soft parts), 

 and the painted semi-circular breast-plate, consisting of several folds of cotton 

 cloth glued on each other, was very similar to those at the British Museum, and 

 the one at Gottingen, except that the characters on that part of the cotton inte- 

 gument which covered the shanks, resembled rather more the figures of the one 

 delineated by Count Caylus, in his Recueil, &c. vol. 5, tab. 26 — 29. Nothing 

 remained of the head but some pieces of the bones of the face, a few teeth, and 

 the mask, which still adhered to the cotton bandages. Among the teeth I found 

 the incisores, which notwithstanding the tender age of the person, had however a 

 very shurt thick crown, considerably worn away at that edge which is usually 

 sharp. This therefore is a new confirmation of the extraordinary phenomenon 

 which I had already noticed in a complete skull, and some fragments of jaws, in 

 my own collection *, and which had also been observed by Middleton in the 

 Cambridge mummy -{-, and by Briickmann in the one that is at Cassel +. Storr 

 has also seen something similar in a mummy that is preserved at Stuttgard ^.
