I'KAKL PRODUCTION. 



The most noteworthy difference between these results and those given above are in 

 the case of the parasites in (A), where Mr. Scott found about 7 times as many as we 

 did. The sample of (B) in this case also, it will lie noticed, is by no means free from 

 infection. Since that time Mr. Scott has examined a few more samples from these 

 same beds with slightly different results, and also a number of batches of mussels 

 from other parts of the coast of the Irish Sea. As these may be interesting for 

 comparison with other localities and other molluscs, we give Mr. Scott's notes, with 

 which he has kindly supplied us, in summarised form, as follows :
