 another number of the Annals. As many of my readers would 

 probably consider this as exceeding the requisite allowance, I

KOYAL SOCIETY. 



On Nov. 4, this Society recommenced its sittings ; when the 

 Croonian lecture, by Sir E. Home, was begun It was entitled 

 " A Further Investigation of the component Parts of the Blood." 



Nov. 11. — The Croonian lecture was concluded. The author 

 attempted to show that globules are to be found in the blood, of a 

 less size, and of a different nature, from those commonly supposed 

 to exist in that fluid. These were first observed by Mr. Bauer 

 during an examination of the layers composing an aneurismal tu- 

 mour. In the coat in contact with the circulating blood, these 

 smaller globules were observed in the proportion of 1 to 4 com- 

 pared with the larger globules, but in the other layers they were 

 more numerous ; and in that which had been first formed, they 

 existed in the proportion of 4 to 1 . Their size was estimated by 

 Mr. B. at -j-gVoth of an inch. In making a section of another 

 aneurismal tumour, crystals of sulphate of lime, and muriate and 

 phosphate of soda, were observed, which salts, as well as the 

 globules above-mentioned, Sir E. supposed to have originally 

 existed in solution in the serum, the globules being only to be 

 seen after the coagulation of the blood had taken place. 



In the coagulated lymph formed during violent inflammation, 

 the same globules were observed mixed with a few colourless 

 blood globules. In the upper and firmest coat of the buff of 

 blood, they were likewise very numerous, but the lower and 

 softer parts were found to be composed chiefly of blood globules. 

 To distinguish these globules from the larger blood globules, the 

 author proposed to call them globules of lymph. 



The author proceeded to state that the quantity of carbonic 

 acid gas evolved under the exhausted receiver of an air-pump 

 from bufty blood was much less than that from healthy blood, 

 but that by far the greatest proportion of this gas escaped from 

 the blood of a healthy person drawn an hour after a full meal. 



Mr. Bauer found both lymph and blood globules in the mucus 

 of the pylorus and duodenum. In the chyle, he found the size 

 of the globules various. Mr. B. supposes that the blood globules
