336 CONTRIBUTIONS TO THE ANATOMY OF THE BRACHIOPODA 



I felt justified in trusting to what seemed my very distinct recollection 

 of its sense. I had the less hesitation in doing this, as in M. Vogt's 

 subsequently published ' Zoologische Briefe^,' he gives the received 

 interpretation to the parts of the so-called ' hearts ' without any in- 

 dication of a change of opinion. 



I make this statement in explanation of what might otherwise 

 seem to be great carelessness on my part, and for the purpose of 

 further pointing out that M. Vogt not having made the supposed 

 discovery, it is quite impossible that Professor Owen's researches 

 should have been suggested by it.
