QUARTERLY CHRONICLE OF MICROSCOPICAL SCIENCE. 79 



SO do, in general, all substances which depress the animal 

 temperature, as external cold, quinine, hydrocyanic acid, 

 and intoxicating doses of alcohol. Morphia is an exception, 

 since, though it generally reduces animal temperature, the 

 corpuscles become larger under its influence. Finally, acute 

 anaemia (produced by arterial haimorrhage) increases the 

 dimensions of the corpuscles. A. more detailed account is 

 promised. 



2. " Kerner on the White Blood-cells and their Alteration 

 by Quinine." (Pfluger's ' Archiv,' vol. v. p. 27.) 



IV. Epithelium— 1. Robinski (' Reichert's Archiv,' 1871, 

 p. 184:) discusses the microscopical and microchemical rela- 

 tions of the so-called cement substance (kittsubstanz) of 

 Recklinghausen and others, which has been supposed to exist 

 between epithelial cells and other structures, on the ground 

 of their behaviour with silver solutions. He denies the 

 existence of this substance in toto. 



2. Lott (' Centralblatt,' No. 27, Sept. 16th) gives a pre- 

 liminary notice of researches on the structure and physio- 

 logical regeneration of epithelium, especially that of the 

 cornea. 



3. Theelaborate article of Ranvier on epithelium ('Nouveau 

 Dictionnaire de Medecine et Chirurgie,' vol. xiii, p. 675) 

 should not be omitted, though published last year. 



V. Connective Tissue and Fat. — 1. "The Structure and 

 Development of Tissue,^' by F. Boll Q Schnitzels Archiv,' vii, 

 276), including (1) tendon; (2) cartilage; (3) fibrillated 

 connective tissue ; (4) development of the same in the ger- 

 minating lien's egg {' Sch. Arch./ viii, 28). (The commence- 

 ment of along and laborious series of investigations ) 



2. "Physiology oftheFat-cell/'byW. Flemming ('Schultze's 

 Archiv,' viii, p. 328). A continuation of his previous re- 

 searches (see same vol., p. 32, ' Q. J. M. S.,' vol. xi, p. 295). 

 He has now studied atrophy of fatty tissue and also its 

 condition in inflartimation. Discusses the differing views of 

 Toldt. 



3. Ranvier (^ Comptes Rendus,' July 10th, 1871) has 

 studied the morbid alterations of the loose connective (or 

 cellular) tissue in oedema. 



4. A paper on " The Structure of Tendon," by Lanzilotti- 

 Buonsanti {' Sulla struttura dei tendini,' Milano, 1871) is 

 referred to in ' Centralblatt,' No. 40, Sept. 30th, 1871. 



5. Flemming (' Ueber Bindesubstanzen bei Mollusken,' 

 Rostock, 1871 ; ' Centralblatt,' No. 41, Oct. 7th), de- 

 scribes the connective tissue of the mantle of the Lamelli- 

 branchiata. He finds it to be a very peculiar structure.
