Lieut. -Col. Walker on the Results of [Dec. 20, 



of granulation corpuscles, or they are multiple, exactly like those of pus- 

 cells. Whole layers of perfect pus-corpuscles are thus formed. But, of 

 course, more complicated shapes occur as well. Among these, for instance, 

 many such pus-cell-like bodies enclosed within one large sphere. 



If, instead of water, serum be added to the thinly-spread myeliue, bi- 

 concave disks will form, only generally much larger than blood-corpuscles. 



" Cells " being thus merely the physical result of chemical changes, they 

 can no longer afford a last retreat to those specific forces called vital. 

 Physiology must aim at being something more than the study of the 

 functions of a variety of ultimate organic units. And pathology will gain 

 new hope in considering that it is not really condemned to be the inter- 

 preter of the many abnormities to which the mysterious life of myriads of 

 microscopical individuals seemed to be liable. 



II. '^^Preliminary Notice of Results of Pendulum Experiments 

 made in India/"* By Lient. -Col. Walker^ F.E.S. : in a Letter 

 to the President. Eeceived September 21, 1866. 



I have the pleasure to inclose a provisional abstract of the results of 

 Capt. Basevi's observations with his pendulums during the past field 

 season. Though provisional, it will probably be found to agree very 

 closely with the final results, which will be deduced as soon as the correc- 

 tions for buoyancy, temperature, &c. are finally known. 



Already these experiments are beginning to throw light on the subject 

 of Himalayan attraction ; for the observations clearly show that the force 

 of gravity is less than it should be theoretically at the stations in the 

 vicinity of the Himalayas, and that the difference between theory and 

 practice diminishes the further the station is removed from the Himalayas. 



This is a remarkable confirmation of Airy's opinion, that the strata of 

 the earth below mountains are less dense than the strata below plains and 

 the bed of the sea. 



Combining these observations with those that were used by Mr. Baily 

 (including, I believe, all your own), the value of the ellipticity will be 

 diminished from to gig (approx.), and will therefore tend more 

 closely to assimilate with Capt. Clarke's value, -^ir*'
