This apparatus has been designed by W. W. M'D. Mackey, F.I.C., of Leeds, to meet the want of an efficient 

 ami quick method for testing the liability of oils to develop heat spontaneously under the conditions obtaining in 

 cloth mills. 



The method is essentially a comparative one, so that the instructions given must be rigorously followed if 

 results comparable with those of other operators are to be obtained ; and it is recommended that before proceeding 

 to the testing of actual samples, a few experiments be first made, say, with a good fresh olive oil and a cotton seed 

 oil as representing a dangerous oil, and the results obtained compared with those given in the tables.
