asimal fluibs. 147 



•ji'boy \vhoha<l died suddenly, in order to ascertaiin the cause of Examination 

 his- death. The whole quantity collected was abovit half an p^j.j^^^41i.'*^^ 

 '.ounce ; it was nearly of the qolour and appearance of the serum 

 of the blood, - 



1. A quantity of- i't was slowly evaporated, and 4 residuum 

 ^vas left, amounting to -^ of the whole. ,.,,.-• 



2. A quantity of the fluid was kept for seme tiine. at the 

 lieat of boiling water ; it became considerably ppake.and gela- 

 tinous. ■ ' ' 



' 3. -A Gopious precipitate was produced by thi) oximuriate of 

 mercury. • 



4. After the flaid was saturated with the oximuriate of mer- 

 cury, it produced no precipitate with the infusion of galls* ? 



5. The nitrate of" silver produced a precipitate which indi- 

 cated both animal matter and the muriate of soda. 



6. A quantity of the coagulated fluid, No. 2, being dried in 

 the temperature of boiling water, was afterwards washed with 

 toiling distilled water. 



7. The water from No. 6. gave no precipitate with the o^:i- 

 muri ate of mercury, nor with galls, but a pretty copious one 

 with the aqua lithargyri acetati. 



The small quantity of the fluid which I was able to obtain 

 prevented me from [)rosecuting the analysis with more minute- 

 ness; from these experiments, however, we may form some 

 idea of its composition. From the 1. we learn that it contains 

 t)2 of water ; from No. 2. and 3. that it contains a considerable 

 quantity of albumen, which I should estimate at somewhat more 

 than ^'-5 of its weight. No. 4. and 7. show that it contained no 

 jelly. No. 7. that it contained mucus; and No. 5. that it 

 contained common salt, but the proportion of this latter appear- 

 ed not very considerable. The constituents of the liquor peri- 

 cardii will therefore be: 



Water 92. 



Albumen 5 5 



Mucus 2 "J The -proportion of these sub-. 



Muriate of soda 5) stances is somewhat conjectural.

The next analysis that I attempted was that of the saliva; Examination of
