    Mentions Dynamoscope for Testing Vitality._ vibrations of surrounding objects. In certain extreme cases the subcutaneous tissue may be laid open, and the instrument applied directly upon it, by which means the vital murmur may sometimes be detected after having become imperceptible at the surface. Having now described and ascertained the nature of the said Invention, 5 and the manner of carrying it into effect, I would have it understood that I do not confine myself to the precise mechanical details of the dynamoscopical instruments so long as their principles and characteristic features be retained. By what I claim and desire to secure by Letters Patent, is, the improved combination of acoustic apparatus, substantially as herein set forth and repre- 10 sented in the annexed Drawing, by means of which, applied as above described, the presence and degree or cessation of vitality in the human body, and in animals of the upper scale, may be ascertained and translated into signs of known value. In witness whereof, I, the said Marc Antoine Frangois Mennons, 15 have hereto set my hand and seal, this Twenty-fourth day of October, in the year of our Lord One thousand eight hundred and sixty-one. M. F. MENNONS. (l.s.) LONDON: Printed by George Edward Eyre and William Spottiswoode, Printers to the Queen's most Excellent Majesty. 1862.
