Sta-May I be allowed to point out to your readers that the clinical brand of Christianity which has just been the subject of a public lecture here in Hong Kong did not originate with Mrs. Eddy at all, but with one Phineas P. Quimby, who actually coined the phrase Christian Science.". Quimby was a quack who treated Mrs. Eddy for gastris trouble, and she wrote to him to say :- Your angel-visit has removed al my stomach-pain. was from Quimby that Mrs. Eddy got most of those weird ideas which are developed in that amazing book Science and Health," although of Or, on the other hand, have they course neither she nor ber followers not sufficient courage to tell the would CYET confcas the fact. truth on occasion and say when Quimby's removal of Mrs. Eddy's circumstances warrant-The per-stomach ache is probably the first formance was ratten!"-Yours, etc., instance of "absent treatment

Impurities In Suspension. The dirty appearance of waste engine oil is due almost entirely to the presence of suspended matter in such a fine state of division that it is not removed readily by sedi mentation. It consists largely of minute particles of carbon produc in the cylinder head by the partial burning of the lubricant and is conveyed to the crankcase through the medium of the retura ed oil. So finely powdered is most of this carbonaceous matter that it cannot be separated by filtration through the most closely woven gauze filters obtainable, and on ac count of this fact and its, non- abrasive nature, its presence has little deleterious effect on the lubricating properties of the oil.
