SODA-WATEB TAP. 
TO THE EDITOR OF THE PHARMACEUTICAL JOURNAL. 
Sir,—No perfect soda-water tap is, that I am aware of, before the public; all 
that I have met with have faults. A gentleman, who has bought several at our 
establishment, one day brought me a French one that he had had lying by for a 
long time. He said it had but one fault, but that was fatal to its utility 5 it 
was so badly constructed that it leaked rapidly at the tap. If this tap was per¬ 
fect in other respects, I thought it could not be difficult to make it sound, so I 
applied to Mr. John Short, mathematical instrument maker, 12, New Street, 
Kennington, and his practical skill has produced what I believe to be a perfect 
instrument. I enclose you a sketch of the tap, which he has taken for me, and 
it hardly needs explanation:—A is a tube pierced at the 
lower end with several small holes; below these holes a 
solid screw is riveted in, for the purpose of boring through 
the cork. B may be said to be a continuation of A, and 
serves to give a proper direction to the aerated fluid after 
it has passed the tap. C is the tap, on the perfection of 
which the chief value of the apparatus depends *, at all 
events, an imperfect tap would completely nullify the other 
advantages the instrument possesses. F) is a handle of 
hard wood or ivory, fixed on a solid continuation of the 
tube A. The instrument, when electro-plated and polished, 
has a very nice appearance, and, being all in one piece, 
nothing can be lost. I will not pretend to advance any 
theory in support of the advantages derived from a long- 
tube reaching to the bottom of the vessel to be emptied; 
it might be met by an assertion, that as the pressure is the 
sameln all parts of the vessel it could make no difference 
whether the tube be long enough to reach the bottom or 
only just to pierce the cork, and to this assertion I do not 
think I could find a satisfactory reply ; I therefore limit 
myself to stating that in practice the long tube is found to 
have the advantage. n t 
I have given Mr. Short’s address, because, as he has succeeded so well, 1 nave 
no doubt there are others who will be glad to avail themselves of his services. 
I have a word or two upon the present adulterations of carmine, and also 
upon the action of zinc on olive oil; but as I have perhaps already exceeded 
the space at your disposal, I will reserve them for another occasion. 
1 lam, Sir, your obedient servant, 
Upper Sydenham , near London. J- ^L HOLLOWAV.

TO THE EDITOR OF THE PHARMACEUTICAL JOURNAL. 
gi r> _Jn the Journal for April, under this heading, a correspondent at 
Scarborough drew attention to the lamentable state into which trade is 
falling in the north of England, illustrating his remarks by informing jis how 
they manage the sixpenny feeder trade there. The statement made by your 
correspondent appears to have been received with much incredulity; but, Sir, 
I can vouch for its accuracy in several respects. 
In this town fittings for sixpenny feeding-bottles may be had for threepence,
