96 SALMONID.E. 



that two animalcules had slipt into the egg, and that double 

 fishes have been generated ; and although they had two 

 bodies, they had but one common stomach : how this hap- 

 pens, see Section V. 1. 



" 12. Of these monstrous productions the most of them 

 were opposite to one another, and had their stomach in com- 

 mon between them : yet, in a strict sense, the stomach only ; 

 the rest of the intestines divided in about three weeks sepa- 

 rately. 



"13. Some of these double fishes were fixed by their sides 

 together, when two animalcules of the sperma enter the egg in 

 a direct line 90 degrees one from another. 



" 14. I have seen only one of these double fishes where 

 the backs were crossed nearest the tail in a direct angle, so 

 that this fish formed a kind of cross. This happens when 

 two animalcules enter one egg, and are placed opposite each 

 other from their direct line to 90 degrees. 



" These monsters, 12, 13, were grown together from the 

 head to the opening in the belly, and that 14 had in some 

 degree a joined body, but the backs were distinguished one 

 from another. 



" 15. All these kind of monstrous productions die in 

 four or five weeks, after their joint bag or belly is emptied ; 

 for as each endeavours to follow its own direction in pursuit 

 of food, and both hinder one another, neither of them is 

 capable of performing its intention; it is impossible that either 

 head can receive its proper nourishment, therefore they must 

 starve. 



"16. All monstrous productions in the human and other 

 animal creations, with a joint stomach, are produced when 

 an egg is fructuated by more than one spermatic animalcule. 



" 17. All observations made on the Trout, and i}s artifi- 

 cial method of breeding, hold good with regard to Salmon.
