8 By the addition of the nitro-iiiunate of tin, the fhiid was* 

 I'endcred considerably more opake, and, as if approaching' to" 

 Cfiagulation after some time a precipitate \vas formed, 



9. X^c residuum from No. 3. was partly dissolved by being 

 digested in hot water. 



10. The water from No. 9. produced a copious precipitate' 

 vvitli nitrate of silver. 



11. It also produced a perceptible precipitate with oxalic 

 acid. 



12. It also produced a slight precipitate with the infusion of 

 galls. 



13. A quantity of this fluid, being evaporated very sTowl}-, 

 loft cubical crystals of common salt in considerable quantity. 



From No, 3, we learn that 97-8 parts in 100 consist of 

 water. From 4. and 5. we learn that it contained a little albu- 

 men. The quantity was too small to be collected and measur- 

 ed by weighing ; but, from the visible effect produced by heafi 

 and the oximuriafe of mercury, I should conceive it could 

 iiot be more than yj© of its weight. Frdm No. 6. and 12. and 

 by comparing 6". with 5. we learn that it contains a minuta 

 quantity of jelly. From- 7. and S. especially by comparing 

 them together, we learn that it contains mucus. By com- 

 paring 7. and 8. and from tO, and 13, wc learn that it 

 contains the muriate of soda in considerable quantity ; and 

 fi'om IT. that it contains a very small traceof lime. The com* 

 position of the fluid will therefore benearlvas follows : 



These proportions are in some* 



measure conjectural.
