1 In a paper published in the M. J. xiii, (i), as this sheet goes to press, Blochmann states as to 

 Euglypha alveolata, (i) that the parent may towards the end of fission withdraw all proto- 

 plasm from the test of the new individual, leaving its nucleus dead ; (2) that conjugation occurs, as 

 a rule temporary, in one instance, however, two individuals giving origin to a third and unusually 

 large individual, being themselves used up in the process.
