but as it is not, I make the gift for what it is worth. I 
have by this plan made the article to some extent for a 
London house, and have sent them some 30 to 40 carboys ; 
but the demand was only fitful, and although they were 
highly satisfied with the quality and would have given me 
my own price, it was not worth my while to continue the 
process. 
The mode of manufacture is merely to mix a salt of 
ammonia, say sulphate or chloride, with double its weight of 
soda waste or gas lime (either being suitable), and blowing 
into the mixture a jet of steam and passing the vapours 
through condensing apparatus ; the distillate is pure sul- 
phide of ammonium. It may be as well to mix the two 
bodies in a portion of water ; and even in that case it is 
needful to be careful with the condensing pipes, as sulphide 
of ammonium being much more volatile than water, it comes 
over so strong at first as to condense in a solid form. I had 
nearly a serious accident with it, which I name to induce 
caution. I was passing the still when at work, and saw 
something was wrong. I called my manager, who, with the 
man at work, examined the pipes, and found them closed ; 
on opening them with an iron rod there was a flow of liquor 
and a strong blow of gas ; seeing and feeling this, I called to 
the man to leave it instantly, but he hesitated. My manager 
then seized him by the arm and pulled him away, and he 
instantly fell down and became rigid as a log of wood ; his 
hreast was now rubbed forcibly to bring on breathing, which 
had quite stopped, and a doctor who was sent for poured cold 
water on his head. He now went into most violent convulsions, 
which lasted over an hour and a half, when he got gradually 
round and was able to work next day. I ascribed the saving 
of his life to the rubbing of his breast, as complete asphyxia 
had taken place with the rigidity of death. Sulphuretted 
hydrogen is most powerful in its effects on animal life, but 
when combined with ammonia it seems even more active ;
