Apparatus, pure Chemicals, and all the requirements for the practice of Photography. Instruction in the Art. THE COLLODION AND POSITIVE PAPER PROCESS. By J. B. HOCKIN.

Every instrument warranted. The peculiar advantage of these pianofortes are best described in the following professional testimonial, signed by the majority of the leading musicians of the age:--"We, the under-signed members of the musical profession, having carefully examined the Royal Pianofortes manufactured by MESSRS. D'ALMAINE & CO., have great pleasure in bearing testimony to their merits and capabilities. It appears to us impossible to produce instruments of the same size possessing a richer and finer tone, more elastic touch, or more equal temperament, while the elegance of their construction renders them a handsome ornament for the library, boudoir, or drawing-room.
