HISTOLOGY. 



I. Text-books,' &c. — The fifth and concluding part of 

 'Strieker's Histology' contains the following articles: — 

 Continuation of ' The Organ of Hearing,' by Rlidinger and 

 Waldeyer ; 'The Olfactory Organ,' by Babuchiii ; 'The 

 Retina/ by Max Schultze ; other parts of the eye, by 

 Iwanoff, Leber, Schwalbe, Babuchin, and RoUett ; 'The 

 Lachrymal Gland,' by Boll ; ' The Uterus and Appendages,' 

 by Chroback, Reitz, and Griinwald ; and ' The Development 

 of the Simple Tissues,' by Strieker. 



Rindfleisch's ' Pathological Histology ' is announced to 

 appear in an English translation, under the auspices of the 

 New Sydenham Society. 



The new part of Henle's ' Anatomy' (vol. iii, part 2) con- 

 tains " The Brain and Spinal Cord," giving very full histolo- 

 gical as well as topographical descriptions. 



II. The Cell in general. — Eimer, " On the Structure of the 

 Cellular Nucleus" (' Schultze's Archiv,' viii, 141), finds the 

 nucleolus in a large number of cells (skin, connective tissue, 

 ganglion-cells, smooth muscle, fibre-cells, &c.) marked off 

 from the rest of the nucleus by a ring of granules, external 

 to which was usually a circular zone, paler than the rest of 

 the nucleus. 



III. Blood.— I. Manassein ('Centralblatt,'No. 44, Oct. 28th, 

 1871) gives the result of more than 40,(T00 measurements 

 on 174 different animals, intended to show the effect of 

 various physiological and morbid influences on the size of 

 the red corpuscles. In general, influences which raise the 

 temperature of the body were found to diminish the size of 

 the corpuscles, such as very high temperature of the ex- 

 ternal medium, or septic poisoning. Excess of carbonic 

 acid in the air also acts in the same way. OxygeUj on the 

 other hand, increases the dimensions of the corpuscles, and
