adopted in the case of samples containing a number of 

 organisms which required for their separate identification a 

 greater time than we had at our disposal. 



It will be evident that this method does not involve 

 wholesale removal of animals from the " Station " under 

 investigation, with consequent disturbance of the balance of 



The details of each " Haul " were at once entered in a 

 journal. A Eoman numeral being assigned to the Haul, 

 and a (Greek) letter to the "Position" from which specimens 

 were taken. Thus any sample preserved was labelled with 

 a numeral and a letter, giving ready reference to full details 

 recorded in the journal. In illustration of the practical 

 details of the work, we introduce here a page from our 

 journal. It would be useless to transcribe the journal in 

 its entirety, since the observations formed only a single series, 

 and gave us, through their short duration, no opportunity of 

 discovering variations in the fauna in relation to changes in 

 temperature, weather, etc.
