vegetable matter, for agricultural purposes and the fertilization of waste 
lands, through the application of this cheap and self- supplying source of 
unfailing production. 
4. The manufacture of urea, extracted from the urine, which manure pos- 
sesses the most fructifying qualification. 
5. The preservation of dead bodies from putrefaction — and thus aiding the 
purposes of dissection. 
The experiments made at Brussels were not of a private nature The 
operations were performed in the presence of M. Liedts, the governor of the 
province, Count de Mevode, M. Duidal, M. Gerburt, the manager of the 
Chambre, the Commissioners appointed by the Medical Committee, editors of 
the public press, &c. A privy containing 8000 pints or 80 cubic yards was 
disinfected with 80 pints of re-agents, and half-an-hour afterwards the empty- 
ing was commenced in the presence of the abovenamed officers, without any 
one being able to detect the least odour. In France, knackers’ yards near 
Paris, and at the very gates of Saumur, were disinfected. These places, the 
receptacles of an enormous quantity of putrid matter, carcasses of horses, 
blood, urine, night-soil, &c. &c., emitting the most disgusting and pestilential 
exhalations, were purified in the course of a few mihutes ; and these reservoirs, 
which were the pest of the neighbourhood, remain ! So satisfied were the 
French and Belgian governments, as also the local authorities, that they have 
applied the process to all the public establishments belonging to the crown, 
the theatres, prisons, stables, hotels, &c. &c. 
“ We have been given to understand by a gentleman who is acquainted 
with Mr. Ellerman, and who takes a warm interest in the “ health of towns” 
question, that he proposes shortly to make experiments, and intends to invite 
scientific and literary men to visit the operation. It appears that he has used 
several different kinds of re-agents, as well as a powder, which latter is highly 
useful for the permanent disinfection of stables , as it neutralises the escape of 
carbonetted ammonia and other volatiles. 
“ Would it not be advisable for the metropolitan and other sewage manure 
companies to avail themselves of this process to disinfect their sewage water 
and other manures ? By this means the odour which many complain of 
would be effectually removed, and the value of the manure increased. It 
would also be wise if the government and individuals were to have their 
stables disinfected by the process , as the ammoniacal vapours must greatly 
injure the health of horses , who are in many instances compelled to breathe 
pestilential vapours in almost air-tight stables. We would also call the atten- 
tion of Cattle Insurance Companies to so great a desideratum, as in many in- 
stances disease is to be traced to the vapours which exhale from the urine and 
dung of the cattle.” 
Acting on these hints, we have made it our business, by institut- 
ing inquiries in quarters wherefrom any information is likely to be 
obtained, and making such experiments as we could conveniently at
