grass, the formation of nitric acid and saltpetre, also many other 

 phenomena, are only caused by the powerful action of oxygen in a 

 nascent state, or with its negative electricity developed." 



From 1845 to 1867 thousands of contradictory opinions have 

 been written on the subject of ozone, but men of science are now 

 returning to the idea clearly pointed out above. The Abbe Moigno 

 has so often pleaded the cause and defended the interests of English 

 scientific men, that we consider it a duty to lend our influence to 

 establish his claim to this forecast of a great discovery.

Morphology. 



A new Gland in the Human Body. — Yon Luschka of Tubingen 

 drew the attention of Human anatomists lately to the presence of 

 an undescribed gland situated at the terminal extremity of the 

 human backbone, which he called the Coccygeal gland, comparing 

 it with the pineal gland. Krause has since found the same body 

 more largely developed in Macacus cynomolgus — and Meyer has 

 examined the tails of the dog, rat, and mouse for a similar 

 structure, but without success. In the cat, however, a similar 

 structure was found. Meyer is inclined to regard this very remark- 

 able body as similar to the caudal hearts or retia mirabilia, which 

 are appendages of the arterial system in many animals. 



Cervical Bibs in Man. — A case of a woman is recorded by 

 Dr. Stieda of Dorpat, in which a pair of cervical ribs sprang from 

 the seventh cervical vertebra. The ribs appear to have been well- 

 marked fully formed pleurapophyses, and were attached by cartilage 

 below to the sternum. The other vertebras in the body were 

 normal. 



Professor Humphry on the Chimpanzee. — Two specimens of 

 the Troglodytes niger have been dissected lately by the Professor of 

 Anatomy at Cambridge, and he gives some account of his observa- 

 tions in the 'Journal of Anatomy and Physiology,' the second 

 number of which has just been published. Professor Humphry 

 makes some excellent remarks on the joints of the limbs, and 

 points out the way in which structure is here concurrent with habit. 

 He dwells on the differences between man and the ape, and dis- 

 cusses the use of the word Quadrumanous. If we are to regard 

 that extremity of a limb which is adapted for grasping as a hand, 

 then assuredly the ape's hind-limb-extremity is as much a hand as
