HYLOZOISM AND HYLO-IDEALISM. 
I he supporters of any thesis which tends to revolutionise 
cut rent ideas ought to give a patient hearing to every opponent, 
howevei gross may be his misconceptions and however abusive 
his language. I hope soon, with your kind permission, to 
answer Mr. Billing’s late articles on Hylo-Idealism. At 
present I have only time to comment very briefly upon the letter 
of your correspondent “ F. P. L.” He falls into the usual con- 
fusion between the world as appearance and the world as actuality. 
Mountains, rivers, and seas, sun, moon, and stars, and the phe- 
nomenal human brain, are fashioned into the forms which we 
know by the actual human brain. What I find “ nauseous ” is

universe which he procreates. The actuality of things is un- 
known to us, save by its manifestations in the sphere of sense 
and thought ; but I have tried to show that these manifestations

ticles on “Animal Automatism,” “ The Identity of Vital and 
Cosmical Energy,” “ The Philosophy of Thomas Carlyle,” in 
the “Journal of Science ” for April, May, and June, 1882, and to 
“The Brain Theory of Mind and Matter” in the issue for 
March, 1883.

THE TREATMENT OF LONDON SEWAGE. 
Many complaints have been made that nothing was done to- 
wards the purification of the immense volume of sewage poured 
into the Thames at Crossness and Barking Creek with every 
turn of the tide. Something is being done at last, and that 
something, if it effects nothing else, will make a very handsome 
addition to the present outlay without the possibility of any set- 
off. Chloride of lime, I believe from 100 to 180 tons daily, is 
being put into the river. As this material is worth £9 per ton,
