X HIS Society resumed its sittings on the 4th of November, by 

 commencing the reading of theCroonian Lecture, by SirE. Home, 

 entitled " A Further Investigation of the component Parts of the 

 Blood." 



Nov. 1 1. The reading of Sir Everard's Lecture was concluded, 

 in which he attempts to show that smaller globules and of a dif- 

 ferent nature from those commonly supposed to exist in blood, 

 are found in it. They were first observed by Mr. Bauer while 

 examining the layers composing an aneurismal tumour. They 

 were seen in the coat in contact with the circulating blood, in 

 the proportion of 1 to 4, compared 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 estimated size was -^-^-^ of an inch. Crystals of muriate 

 and pjiospliate of soda, and sulphate of lime were found in making 

 a section of another aneurismal tumour : these and the globules 

 before mentioned Sir E. supposes to have originally existed in 

 solution in the scrum ; the globules being to be seen only after 

 the blood has coagulated. In coagulated lymph, found during 

 high inflammation, these globules were observed mixed with a 

 few colourless blood globules. They were also found in great 

 numbers in the upper firm coat of the buff of blood, while the 

 lower and softer parts consisted chiefly of blood globules. The 

 author proposes to call the new globules by the name of globules 

 of Lympk^ to distinguish them from blood globules. The author 

 found the quantity of carbonic acid gas evolved from bufFy blood 

 under an exhausted receiver to be much less than that from 

 heallhv l)lood ; and that by far the greatest quantity of this gas 

 was yielded by blood drawn from a healthy person an hour after 

 a full meal. — Both lymph globules and blood globules were found 

 in the mucus of the pylorus and duodenum. In chyle the size of 

 the globules is various. Rlr. JSauer supposes that the blood,
