76 J. H. ORTON. 
Not more than upwards to about 50 fish were boiled at a time, and a 
shallow tray which just fits into the fish kettle was used for containing 
the fish during boiling, one tray being used for boiling while the boiled 
fish in another tray were being cleaned. 
It was found that with one worker cleaning the fish roughly, another 
worker could clean up to 30 skeletons in an hour after a little 
practice. The skeletons of the whole sample in each case were prepared 
in two working days by one worker cleaning them roughly and two 
others cleaning them finally. All the skeletons have been kept with their 
own label for future reference and comparison with others. It was found 
important not to clean the skeletons too well in the region in front of the 
anterior complete hamal arches, and to cut the vertebral artery at an 
early stage in the cleaning operation. The prepared skeletons were kept 
in shallow wooden trays. 
DISTRIBUTION OF WORK AMONG THE WORKERS. 
The work in the different stages was accomplished with the help of 
workers who gave their services at different times. The responsibility 
for the method and form of the work was undertaken by Dr. Orton, but 
the assistance rendered by the team of helpers can best be shown in 
tabular form as follows :—

Mr. William Searle assisted in handling and labelling the fish and labelled 
the gut with attached pyloric ceca for further examination. 
It may be mentioned that a fair amount of practice in measuring, 
weighing, recording, and counting was done by Dr. Orton, Mr. Smith, Miss 
Clark, and Mrs. Orton before the large samples were investigated.
