* * * * * _From_ DR H. H. PIERSON, _Professor of Music, Edinburgh_. Many thanks for your staff, which is an excellent idea, and a very useful invention, as well as the cylinders. The advice contained in your ‘Finger und Handgelenk Gymnastik,’ together with the set of regulations there laid down, is of eminent value, if properly attended to, as a means of preparing the fingers and wrists for playing the piano, violin, &c., and for rendering them strong and flexible, the two indispensable requisites. I particularly admire the extreme simplicity of all your inventions, which really remind one of the ‘Egg of Columbus,’ and I should not be surprised if your ideas (so disinterestedly offered to the public) were to introduce a new era in the study of the pianoforte and stringed instruments. They must also be of signal service to organists, to whom I should specially recommend your apparatus.” * * * * * _From_ HERRN LAUTERBACH, _Violinist_. “Being always very much in favour of gymnastics of all kinds, I hasten to inform you that your discovery relating thereto has interested me very much, and I am satisfied that great good will arise from it.” * * * * * _From_ HENRY BLAGROVE, _Professor of the Royal Academy of Music; Leader of the Philharmonic Society; of the Musical Society of London., &c., &c._ _July 22nd, 1865._ “On perusal of your MS. relative to the development of the muscles of the hands, &c., as applied to musicians, I have great pleasure in offering you my testimony to its being a valuable adjunct to musical tuition where mechanical action is required, such as for the piano, or violin and violoncello. I think it shortens the usual routine of practising to gain strength, and will give at once freedom and force to the hand, fingers, arm, &c.” * * * * * _From_ J. T. CARRODUS, _Leader of Her Majesty’s Theatre_. _July 23rd, 1865._ “I am convinced that Mr Jackson’s invention for the development of the muscles of the fingers and hand will be of great value to musical students.” * * * * * _From_ E. AGUILAR, _Pianist_. _July 22nd, 1865._ “I consider Mr Ward Jackson’s system for the fingers remarkable for its simplicity, ingenuity, and efficacy. I believe that its universal adoption must materially benefit and assist all who cultivate instrumental music.” * * * * * _From_ W. GEO. CUSINS, _Pianist, Organist to Her Majesty_. _July 27th, 1865._ “I beg you will permit me to say how much interested I was this morning with the highly ingenious method of developing the hand you were kind enough to explain to me. I believe your discovery to be of great importance to musicians who use their fingers. For myself I intend trying your system, and shall likewise make my pupils use it.” * * * * *
