COMPANY. 

 95 MILK ST., BOSTON. MASS, 



This Company owns the Letters - Patent 

 No 186,787, granted to Alexander Graham 

 Bell, January 30th, 1877, the scope of which 

 has been defined by the Supreme Court of 

 the United States in the following terms : 



"The patent itself is for the mechanical 

 structure of an electric telephone to be used 

 to produce the electrical action on which the 

 first patent rests. The third claim is for the 

 use in such instruments of a diaphragm, 

 made of a plate of iron or steel, or other ma- 

 terial capable of indactive action: the fifth, 

 of a permanent magnet constructed as de 

 scribed with a coil upon the end or ends 

 nearest the plate; the sixth, of a sounding 

 box as described ; the seventh, of a speaking 

 or hearing tube as described for conveying 

 the sounds; and the eighth, of a permanent 

 magnet and plate combined. The claim is 

 not for these several things in and of them- 

 selves, but for an electric telephone in the 

 construction of which these things or any of 

 them are used."

THE MODERN MALADY ; or, 

 ferers from ' Nerves.' 



An introduction to public consideration, 

 from a non-medical point of view, of a con- 

 dition of ill-health which is increasingly 

 prevalent in all ranks of society. In the 

 first part of this work the author dwells on 

 the errors in oui' mode of treating Neuras- 

 thenia, consequent on the wide ignorance of 

 the subject which still prevails; in the sec- 

 ond part, attention is drawn to the principal 

 causes of the malady. The allegory forming 

 the Introduction to Part I. gives a brief his- 

 tory of nervous exhaustion and the modes of 

 treatment which have at various times been 

 thought suitable to this most painful and try- 

 ing disease.
