X. — On the Mode of extracting Manure from Sewage Water, 

 practised at Cardiff Gaol. By Thornton J. Herapath, 

 Assistant-Lecturer on Practical Chemistry in the Bristol 

 School of Medicine, &c. 



To Mr. Pusey, 



Sir, — Much attention, as you are aware, has of late been directed 

 by agriculturists and sanatorists to the application of sewage and 

 sewerage- water to the fertilization of land ; and consequently any 

 process by which such matters can be at the same time readily 

 and economically defecated, and converted into a good and useful 

 manure, will be doubtless considered of sufficient interest to merit 

 a notice in the Journal. Enclosed in this letter is a sample of 

 prepared night-soil which was recently placed in my hands for 

 analysis ; and as I thought that the process by which it was 

 manufactured might be new to the majority of the members of 

 the Royal Agricultural Society, I have taken the liberty of offer- 

 ing you a few remarks upon it, in the hope that I might thus 

 afford some useful hints vt^hich might serve to guide others in 

 their endeavours to convert what has hitherto proved a cause of 

 disease and annoyance to the community at large into a source of 

 national wealth and importance. 



The specimen of manure forwarded to you was prepared by 

 the prisoners at the Cardiff Gaol, where the mode of manu- 

 facture referred to has been for several years in operation.
