their places of maximum and minimum action accord with the effects 

 of induced currents. Time has great effect over results produced 

 by currents induced in the mass, and none over those due to 

 polarity. By this test the effects of the diamagnetic metals are 

 found due to induced currents. 



The phenomena produced by the use of the present apparatus 

 are then shown to be in close and direct relation to the phenomena 

 of revulsion formerly described by the author : the parallel is closely 

 carried out and extended, and both sets of effects referred to one 

 and the same cause. 



The author endeavours to repeat an experiment described by 

 Reich, but without success ; and he finds that even when iron is 

 used no arrangement of magnets can produce any test of polarity 

 at all comparable to the use of an astatic needle or to suspension 

 between the poles of a powerful magnet, and thinks that arrange- 

 ments which are thus less sensible with iron are not likely to be 

 more sensible with diamagnetic metals, even if they are polar. 



Finally, the author does not consider that the idea of diamagnetic 

 polarity has gained as yet any additional proof beyond the fact that 

 diamagnetic bodies, such as bismuth and phosphorus, are repelled 

 by one or both magnetic poles ; he does not reject the idea of 

 polarity, but his opinion or judgment remains the same as at the 

 time of its announcement in 1845. 



A paper was also read, entitled ^' Contributions to the Chemistry 

 of the Urine. — Paper IV. On so-called Chylous Urine." By H. 

 Bence Jones, M.D., A.M., F.R.S. <S:c. 



The definition given of chylous urine is, that it is urine which is 

 white from the suspension of fatty matter in it. An opportunity of 

 observing a case of this disease having occurred to the author, he was 

 led to make the experiments described in this paper. A harness- 

 maker, age 32, half-caste, who had lived in London for twelve years, 

 had been passing such w'ater for nine months. On examination of 

 the water made at 2 p.m. it solidified, looking like blanc-mange in 

 ten minutes. It was very feebly acid, contained fibrin, albumen, 

 blood-globules and fat; specific gravity= 1015. 1000 grs. of this 

 urine gave — 



44-42 grs. total solid residuco 

 8'01 grs. total ash. 

 14*03 grs. albumen. 

 8-37 grs. fat. 

 13*26 grs. urea and extractive matter. 

 •75 gr. loss. 

 955*58 grs. water. 

 In order to watch the variations jDroduced by food and exercise 

 in the appearance of the urine, every time the urine was made, for 

 five days and nights it was passed into bottles marked with the hour. 

 From these observations, and more particularly from the third, fourth, 

 and sixth days, it was evident that the fibrin and albumen appear in 

 the urine when no fat is there, and that the albuminous urine occurs
