and lobsters are unusually rich in iodine, containing about 200 times 

 as much as such common foods as beefsteak, milk, eggs, etc. Shrimp 

 contain about 100 times as much, and crabs and most marine fish 

 an average of about 50 times as much. Fresh-water fishes were 

 found to contain very small amounts of iodine, the quantity being 

 about the same as that found in milk, eggs, beefsteak, etc. The 

 results of these determinations have been published for the use of 

 the trade.
