This table is constructed from a formula given by the author in his paper. 
Professor Bunsen strongly recommends washing precipitates by this method 
with use of the table, in preference to employing the method generally followed, 
of ascertaining the completion of the washing process by evaporating a portion 
of the filtrate on platinum foil, since the indications so obtained can only be 
trustworthy in dealing with extremely insoluble precipitates. 
The very ingenious vacuum-filter and water air-pump described by the 
author will be noticed in the next number of this Journal. 
THE EXAMINATION OE APOTHECARIES’ ASSISTANTS AT 
THE APOTHECARIES’ HALL OF IRELAND. • 
TO THE EDITORS OF THE PHARMACEUTICAL JOURNAL. 
Gentlemen,—No previous course in Arts or any Apprenticeship is re¬ 
quired at the Apothecaries’ Hall of Ireland from candidates for “ the certifi¬ 
cate of assistant.” 
The Company have given their consent to a Bill having for its object the 
qualification of a class of Pharmaceutical Chemists in Ireland. I publish these 
facts on Dr. Leet’s authority. 
Your obedient servant, 
Thomas J. Monaghan. 
January 13 th, 1869.
