Recent practice substitutes mineral oils properly prepared for animal fats, 

 and though it would seem that in them not enough body existed to properly lubri- 

 cate surfaces under heat and friction, they are found to answer well and stop cor- 

 rosion. This result is probably assisted by the judicious admixture of a certain 

 proportion of animal fat with the mineral oil. However this may be, it is certain 

 that reliable testimony points to the success of properly prepared mineral oils, 

 for cylinder use, and so far as testimony can go, the fact is established. — Me-
