554 A CONTRIBUTION TO THE STUDY OF THE PRECIPITINS. 



During the subsequent years the range of appHcation has been 

 much extended.* Tlie increased attention to public health and 

 food-supply has led to the use of the test in analytical work con- 

 cerned with meat and animal foods generally. A detailed 

 account of the methods employed in the use of the test in routine 

 examinations in a municipal laboratory is given by Fornet and 

 Muller.f The test has also been utilised in medical diagnosis. 

 The application of the test to the diagnosis of hydatid disease, 

 so prevalent in this country, may be cited. The small amount 

 of manipulation required for these tests, and the speed with 

 which a result may be obtained, give this test a great advantage 

 over the test for deviation of complement which is used for the 

 same purposes.
