GooLE Scientific Society. — 

 Meeting March 8th, the president, 

 Mr. M. A. Morris, in the chair. — 

 A paper was read by Mr. James 

 Savage, L.R.C.P., on The Heart 

 and circulation of the Blood." The 

 author said that physiology could 

 never be an exact science until the 

 nature of life itseK was known, but 

 that our knowledge of the function 

 of the circulation of the blood more 

 nearly approached completeness 

 than that of any other branch of 

 the science. This knowledge was 

 in great part due to the labours of 

 William Harvey, an English physi- 

 cian of the seventeenth century. 

 He then described the position of 

 the heart in the chest (oblique only 

 in man and the higher apes), its 

 division into four cavities, its struc- 

 ture and the course of the circula- 

 tion, the aids to the circulation, the 

 respiratory and other muscular 

 movements, the presence of valves 

 in the veins, and the elasticity of 

 the coats of the blood vessels. The 

 stop-cock action of the muscular 

 coat of the smaller arteries, the 

 action of the valves, and the re- 

 tardation of the circulation due to 

 the increased sectional area of the 

 smaller ramifications of the arteries 

 were pointed out. The lecture was 

 illustrated by diagrams, recent 

 specimens, and by injected sec- 

 tions, exhibited by the president 



and Mr. Hunter. — H. Franklin 

 Parsons, M.D., Hon. Sec.

 Margerison, president of the Brad- 

 ford Society, would read a paper at 

 the next meeting (April 1st) on 

 " The Ocean our Natural Store- 

 house." Several carboniferous fos- 

 sils were exhibited, including 

 Lepidodendron, Sigillaria, Calamites, 

 and Pecopteris. Mr. J. L. Adam- 

 son reported that a pair of merlins 

 had been captured at Rawfolds,

Society. — Meeting February 19th, 

 the president, Mr. G. T. Porritt, 

 F.L.S., in the chair. — Mr. Richard 

 Jessop exhibited the roseate form 

 of Erythrcea Centaurium from first 

 year's growth. The discussion on 

 " Corals," adjourned from January 

 meeting, was opened by Mr. Joseph 

 Tindall. Mr. A. Spiegel then read 

 a most interesting paper on 

 ^' Chemistry in the Economy of 

 Nature," after which a lively dis- 

 cussion ensued. For want of time, 

 it was decided to postpone the dis- 

 cussion on the result of that day's 

 excursion to Holmfirth, until the 

 next meeting.
