INTRODUCTION AND GENERAL ACCOUNT 

 OF THE WORK. 



During 1906 the system of quarterly reports which 

 was referred to in the Introduction of the last Annual 

 Report has been continued with the view of bringing the 

 more important matters dealt with in the laboratory 

 before the notice of the Scientific Sub-Committee with as 

 little delay as may be, and has also served to keep the 

 Committee generally better informed as to the progress of 

 the scientific work. 



The Board of Agriculture and Fisheries have sent 

 various specimens to the Liverpool laboratory to be 

 examined. Their Inspectors have visited the laboratory
