83 MEMORIAL SKETCH. 



tinent to continent, sublime as it is, inasmuch as many intellects 

 were combined to effect the latter, while the general tendency 

 of science seems to have been your sole guide in demonstrating 

 that matter is merely the medium through which mind-force, 

 like all other force, acts, and that thus mind may, and in fact 

 does, exist independently of matter. The series which you 

 have completed is very beautiful. First, Mr. Grove's masterly 

 demonstration of the correlation of the physical forces, then 

 your proof of their correlation with the vital force so happily 

 illustrated by the zoospores, and, lastly, the remarkable correla- 

 tion between the vital and mental forces. No doubt this series 

 will mark the middle of the nineteenth century as a great 

 scientific epoch, the discoveries arising from which who can 

 predict, when the motion of a microscopic atom affords irre- 

 sistible proof of an important fact ? The paper you have kindly 

 sent is so full of interesting matter, and contains so much new 

 to me, that it is in vain to write all I should have wished to 

 talk to you about. I can only heartily thank you for it. 



The researches on the Foraminifera, on which Dr. 

 Carpenter had been long engaged, were now drawing to a 

 close. Four successive memoirs upon them had been pre- 

 sented to the Royal Society, and published in the " Philo- 

 sophical Transactions," and on these, together with his 

 investigations into the microscopic structure of shells, his 

 observations on the embryonic development of Piirpiira, 

 and his various other writings in Physiology and Com- 

 parative Anatomy, was based the award of one of the 

 Royal medals, which he received from the President and 

 Council of the Royal Society in i86i. He was still hard 

 at work completing the long-delayed treatise on the entire 

 group, designed for the Ray Society, in which he was 

 assisted by Mr. W. K. Parker and Mr. T. Rupert Jones. 

 With how much eagerness he toiled, even through the hot 

 summer days in which he was detained by University 

 examinations, may be inferred from the following letter 

 to his wife at Holy Island : —
