The day was fine, but the excursion was not so well attended as 

 might have been expected. Possibly Totteridge may be thought 

 by some to be exhausted, but the foregoing list shows that there 

 are still many objects to be obtained in that neighbourhood ; in 

 addition to those enumerated some curious forms of Volvox and 

 some very beautiful Rotifers were found by the Secretary, who re- 

 grets that he had not time to identify them. Other interesting 

 objects were also found by him. 



The number of members of the Q.M.C. who attended the Excur- 

 sion was twelve. Four members of the Hackney Society were 

 also present, as also one member from the S. London ; these with 

 one or two friends, made up a total of nineteen.
