166 OUTLINES OF PERIODICAL LITERATURE. 
mines of Huantaxaya ; Mr. Clarke’s on the peat-bogs and submarine forests 
of Bourne Mouth; Mr. Hamilton’s on the geology of Asia Minor; Mr. 
Strickland’s on some dikes of calcareous grit in Ross-shire ; Mr. Darwin’s 
on the connexion of certain volcanic phenomena, and on the formation of 
mountain-chains and volcanos, as the effects of continental elevations ; and 
Professor Owen’s on the dislocation of the tail, at a certain point, in the 
skeletons of many Ichthyosauri. At a meeting of the Zoological Society, 
Mr. Martin read observations on the Proboscis Monkey; and Mr. Water- 
house directed attention to several small quadrupeds, belonging to the genera 
Phasogale and Mus, which he considered to be undescribed. Mr. Ogilby 
noticed the generic and specific characters of two species of his new genus 
Kemas; Mr. Owen submitted remarks on the cranium of the Orang Outang, 
exhibiting a transitional state of dentition ; and he then offered some obser- 
vations on a preparation of foetal Kangaroo, with its accompanying uterine 
membranes. With intelligence, and miscellaneous articles relating to the 
tartaric and paratartaric acids, to the action of fermentation on a mixture of 
oxygen and hydrogen gases, and to the action of sulphate of ammonia upon 
glass, the Supplement to volume twelfth is concluded. 
JuLy ushers in a new volume, with the plan of education for students in 
civil engineering and mining, in the University of Durham ; the new course 
of study there established is such as to form, not merely a school of civil 
engineers, but also a school of miners, wherein persons likely to be, through 
life, engaged either in excavating the mineral wealth with which the country 
abounds, or in converting the raw material into an article of commerce, may 
obtain such information on these various subjects as may be required. 
Mr. Potter comes next, with remarks on the radii and distance of 
the primary and secondary rainbows, as found by observation, and on a com- 
parison of their values with those given by theory ; and he is followed by 
Col. Emmett, with meteorological observations taken at St. George’s, Ber- 
muda, in the latter halt of 1837. Dr. Bird proposes, in another section of 
his experimental researches on the nature and properties of free and combined 
albumen, chiefly in relation to carbonic acid and electric currents, to detail 
some facts which tend to support his previously expressed remark—that 
these investigations would serve to point out the presence of albumen in 
certain animal fluids in which it was unsuspected, and thus reveal some new 
combinations of this important product of organization. Two articles are 
furnished by Professor Johnston, on the elastic bitumen of Derbyshire as a 
mineral substance having an organic origin, and on the separation of oxalic 
from other organic acids; and, after these papers, comes one by Dr. Hare, 
on the re-action of the essential oils with sulphurous acid as evolved in union 
with zether in the process of eetherification or otherwise. Mr. Holtzapffel 
explains a scale of geometrical equivalents for engineering and other pur- 
poses, adding illustrative figures; and this article is followed by Mr. Lam- 
ing’s doctrines on the primary forces of electricity, in continuation. Mr. 
Binks’ second communication on some of the phenomena and laws of action 
of voltaic electricity, and on the construction of voltaic batteries, embraces 
three sections, intituled subjects of inquiry, the principle of investiga- 
tion, and the method of investigation with preliminary experiments. Tor 
intelligence and miscellanies, you have a record of the circumstances attend- 
ant on the festival in honour of Sir John F. W. Herschel, and in commemo-
