Sewage Treatment : the Native Guano Company : Agricultural 
Show at Aylesbury. — On October 19th a numerous gathering ot 
gentlemen interested in Sanitary Reform and in Agriculture took 
place at the works of the Native Guano Company at Aylesbury. 
The display of farm and garden produce, vouched as being grown 
solely with the “ Native Guano,” or manure, obtained by the 
precipitation of the Aylesbury sewage, was exceedingly fine, and 
was pronounced by practical men most satisfactory. The entries 
were 441 in number, being above a hundred more than at the 
last year’s show. The purification of the sewage is evidently 
most successful. We find that some of the most determined 
opponents of sewage precipitation have overcome their former 
prejudices. Had even the late Royal Rivers’ Pollution Commis- 
sion been present they would have been compelled to own that 
the entire process, from beginning to end, is totally free from 
nuisance. 
•According to the “Medical Press and Circular” Dr. J. B. 
Mitchell challenges Anti-Vaccinationists to an experimentum 
crucis. He proposes that a duly qualified person on behalf of 
the Anti-Vaccinationists shall accompany him to some country 
where physiological experimentation is free, and that a compari- 
son shall be made between the respective results produced by 
smallpox inoculation of recently vaccinated and unvaccinated 
persons. The expenses are to be equally borne by both parties 
at the outset, but as soon as the decision is arrived at the loser 
is to defray the whole. These proposals we learn have been 
communicated to Mr. P. A. Taylor, M.P., and to the “ Echo,” 
but in both quarters a solemn silence has been observed. 
A medical contemporary writes : — “The Society which is so 
careful of the few animals which suffer under the hands of sci- 
entific investigators, whilst it regards unheeding a millionfold 
greater cruelties daily occurring, is not dead, but stunned.” 
Surely, then, this is the time to press on with its exposure, so 
that it may have no time or opportunity for revival ! 
The Corporation of Wigan have been persuaded into disposing 
of their sewage by means of an irrigation farm, at a cost of 
£62,000. Aclaim is now brought against them for £22,664 I25 * 7 ^* 
for the value of the coal underlying half a mile of the line of 
pipe conveying the sewage to the fields. This is a peril of irri- 
gationism which has not yet been taken into account.
