DR. KAHN on MARRIAGE.—A new and
entirely re-written Edition (the 45th) of this celebrated
Treatise, with new Steel Plates, Woodcuts, &c., is now ready.
The object of the work is not to maintain any particular
hypothesis, but to enable every one to understand for himself
the structure and functions of the organs concerned in the
fulfilment of the physical obligations of the married state;
to acquaint him with the consequences arising from excesses ;
to prevent unnecessary misapprehension from unfounded
fears, and to indicate, when those fears are well founded, the
means of speedy relief. The work is not crowded with the
technicalities of ordinary professional books, nor does it pre-
sent the crudeness which characterises the so-called "popular
works" on the subject. . . .

SPECTACLES.-SIGHT AND HEARING.-
DEAFNESS.—A newly-Invented Instrument for ex-
treme cases of deafness, called the SOUND MAGNIFIER,
Organic Vibrator, and Invisible Voice Conductor. It fits so
into the ear as not to be in the least perceptible ; the unplea-
sant sensation of singing noises in the head is entirely re-
moved. It affords instant relief to deaf persons, and enables
them to hear distinctly at Church and at public assemblies.
Every other kind of hearing instruments. Messrs. SOLO-
MONS have invented spectacle lenses of the greatest trans-
parent power. The valuable advantage derived from their
invention is, that vision becomes preserved and strengthened ;
very aged persons are enabled to employ their sight at the
most minute occupation, can see with these lenses of a much
less magnifying power, and they do not require the frequent
changes to the dangerous effects of-further powerful assist-
ance.-39, Albemarle-street, Piccadilly, opposite the York
