nerate. It was similar in its nature to the charcoal left after 

 heating the exhausted roe of the pike. 



From his analysis Morin concludes that the roe of the com- 

 mon trout contains, 



1. Albumen. 7. Phosphorus. 



2. Osmazome. 8. Carbonate of soda. 



3. Gelatin. 9. Carbonate and phosphate 



4. Oil. of potash. 



5. A solid matter resembling 10. Chloride of potassium, 

 coagulated albumen. 11. Phosphate and carbonate 



6. Sal-ammoniac. of lime. 



3. The roe of the carp was analyzed by Morin in the same 

 manner. He obtained, 



1. Much albumen. 6. Chloride of potassium. 



2. Osmazome. 7. Carbonate of soda. 



3. Gelatin. 8. Phosphate of lime and car- 



4. Oil containing phosphorus. bonate of lime. 



5. Coagulated albumen. 



4. M. Dulong d' Astafort analyzed the roe of the barbel in the 

 same way as the preceding analyses had been conducted. It has 

 been long known that the roe of the pike has a purgative quali- 

 ty. And M. Dulong d' Astafort informs us that those of the bar- 

 bel have the same property. This effect is ascribed to the oily 

 matter which both contain, which, instead of being a tasteless 

 fixed oil like that in the yolk of the common fowl, possesses very 

 acrid properties. The roe of the barbel was found to contain 

 the following substances : 



1. Albumen. 7. Sal-ammoniac. 



2. An acrid oil. 8. Phosphates of lime and po- 



3. Osmazome. tash. 



4. Gelatin. 9. An organic salt, with base 



5. Phosphorus. of potash. 



6. Chlorides of potassium and 

 sodium. 



These analyses show a striking analogy between the roes of 

 fishes and the eggs of fowls.
