80 MICROSCOPICAL MEMORANDA. 



the question involved the animality of Monades and Vibriones, bearing 

 more particularly on the question of spontaneous generation as restricted 

 to Entozoa and Animalculse. 



The meeting then resolved into the conversazione and examination of 

 objects.

Mandl on the Relations which exist between Blood, Pus, Mucus, and 

 Epidermis. The general conclusions arrived at by the author in his 

 memoir read before the Socitie Medicale d' Emulation, June 3rd, 1840, 

 are as follows : 1 . The fibrinous globules of the blood, the globules 

 of mucus, and those of pus, are identical. 2. All the globules are 

 the product of the coagulation of the fibrin in the serum, which has 

 transuded through the walls of the blood-vessels. 3. The liquid in 

 which the globules swim constitutes the difference between pus and 

 mucus. 4. If the fibrinous globules remain fixed to the surface of the 

 membrane, where they are secreted, they become the nuclei of epider- 

 moid cellules, which constitute the elements of the epidermis. 5. If, 

 on the contrary, the fibrinous globules remain free on the surface of the 

 membrane, they are expelled by the organism, and form an element of 

 pus and mucus. 6. These two elements are simply filtered blood ; 

 that is to say, they contain all the elements of the blood, except the 

 globules; the serum at the same time undergoing chemical altera- 

 tions. Gaz. Med. de Paris, July 1840, in Brit, and For. Med. Rev.

Locality for Crateriumpyriforme. This beautiful microscopic Fungus, 

 which was first noticed by Mr. C. G. White on flint stones in an old 

 gravel pit at Old Ford, near Bow, Middlesex, is now to be found most 

 abundantly on the gravel pebbles on the banks of the South West- 

 India Dock, and no doubt in other localities at this season. They are 

 not restricted to pebbles only, nor found on every stone, but appear 

 chiefly on the Southwestern aspect. Edward Stock, Poplar, June 15, 

 1841. 



Death of M. Turpin. It is with much regret we record the death of 

 this distinguished microscopic observer and draughtsman. His remains 

 are deposited in Fere la Chaise, Paris. In a future number we intend 

 inserting an abstract of his researches, and further details connected 

 with the life of this illustrious observer.
