These results show — 1st, That with a bismuth and silver 

 thermo-couple, the total Peltier effect was larger at 92° than 

 at 12° 0. ; 2nd, with an antimony and silver couple it was 

 about the same at 95° as at 12° C. ; 3rd, that it was less with 

 an antimony-silver than with a bismuth-silver couple at 

 each temperature ; 4th, with a bismuth- silver couple, the 

 heating-effect at 12° 0. was somewhat greater than the cooling 

 one, and at 92° C the heating and cooling effects were about 

 equal ; and 5th, that with an antimony-silver pair, the heating 

 and cooling effects both at 12° and 95° C. were all about 

 alike. 



With the couples formed of bismuth-antimony, iron- 

 German-silver, and bismuth-silver, the total Peltier effect was 

 greater in each case at the higher temperature than at the 

 lower one, but with the antimony-silver one, the effects at the 

 two temperatures were about equal. 



All the results were probably affected to some extent by the 

 influence of "electric convection of heat." 



The whole of the results obtained (after making due allow- 

 ance for differences in the specimens of metals employed by 

 different experimentalists) agree with the thermo-electric 

 diagram given in the manual on " Heat," by P. Gr. Tait.

J- 1. " On two Rhsetic Sections in Warwickshire." By Eev. P. 



B. Brodie, M.A., F.G.S. 



The sections noticed in this paper were (1) one exposed on a 

 railway at Summer Hill, near Binton, between Stratford and 

 Alcester, and (2) one, 13 miles further to the south-east, at Snitter- 

 field, 3 miles north of Stratford- on- Avon, in excavations for a 

 tunnel connected with a supply of water to that town. 



At the first-named locality a bed with insect remains overlies the 

 firestone and Estheria-bed, and this is succeeded in descending order 

 by a considerable thickness of black and grey shales with the usual 

 Rhsetic fossils. The bone-bed is not exposed. 



At the second locality, in borings and shafts, black Rhsetic shales 

 were found in three places resting upon a denuded surface of new 

 Tied Marl, and covered by between 40 and 50 feet of drift. Avi- 

 cula contorta and other typical fossils were obtained from the shales. 

 In other shafts the Rhsetic beds were wanting, so that apparently
