In it the principles established in the preceding parts were 

 applied to ascertain the exact power of each of the letters of the 

 Egyptian alphabet. Those contained in the alphabet lately pub- 

 lished by Chev.Bunsen were first examined; and then the other 

 characters alleged to be alphabetic: some of which were classed, 

 in Chev. Bunsen's arrangement, among the syllabic signs, while 

 others were altogether omitted. A new class of letters having 

 the power of eh, and corresponding to the Hebrew !!J, is esta- 

 blished, to which the long serpent belongs, occurring in the 

 word chat, signifying ever.

 Chair. 



Mr. Oldham, on the part of Mr. R. Mallet, who was 

 unavoidably absent, described the objects, construction, and 

 use of certain new instruments devised by the latter for self- 

 registration of the passage of earthquake shocks. 



Instruments previously intended for this purpose have not 

 possessed the power of self-registration ; they have consisted 

 either in the trace left by the motion,of a viscid fluid on the 

 containing vessel, or they have been upon the principle of the 

 inverted pendulum, or watchmaker's noddy. Instruments so 

 constructed are objectionable, because having themselves 

 times of vibration of their own, which may conflict with those 

 of the earthquake shock, they are liable to fail in point of 

 delicacy. They also possess several inconveniences of a me- 

 chanical kind in being adapted to self- registration. 



The objects to be attained in the instruments which the 

 author has had in view, are :
