ADDRESS. - lix 
Statistics, Geography, and Ethnology, to which small sums have been as- 
signed. 
The newly issued Report of our Manchester Meeting is admirably calcu- 
lated to maintain the reputation of the Association. Besides a number of 
excellent Reports which are the continuation of researches already published 
in our yolumes, it contains elaborate and important Reports by Mr. Stewart 
on the Theory of Exchanges in Heat; by Dr. Smith and Mr. Milner on 
Prison Diet and Discipline ; by Drs. Schunck, Angus Smith, and Roscoe on 
the progress of Manufacturing Chemistry in South Lancashire ; Mr. Hunt on 
the Acclimatization of Man; Dr. Sclater and M. Hochstetter on the Apteryx 
of New Zealand ; Professor Phillips and Mr. Birt on the Physical Aspect of 
the Moon. Professor Owen contributes a most interesting paper on the 
Natives of the Andaman Islands. The President of the Royal Society re- 
ports the Repetition Magnetic Survey of England ; and Mr. Fairbairn, our late 
President, reports on the Resistance of Iron-Plate Pressure and Impact. 
_ The Transactions of the Sections occupy nearly as much space as the 
Reports, and are replete with valuable and original matter, which it would 
be impossible to particularize. 
Many of my predecessors in their Addresses have alluded to the most 
striking advances that have been made in the various sciences since the last 
Meeting; I will mention a few of these in Astronomy, Chemistry, and 
Mechanics. : 
In Astroyomy, M. Delaunay has communicated to the Academy of Sciences 
of Paris the results of his long series of calculations in the Lunar Theory, 
destined to fill two volumes of the Memoirs of the Academy, The first volume 
was published in 1861; the printing of the other is not yet begun. This 
theory gives the expressions for the three coordinates of the moon under an 
analytic form, and carries those for longitude and latitude to terms of the 
seventh order inclusive, that of Plana extending generally only to terms of 
the fifth order. The addition of two orders has required the calculation of 
1259 new terms for the longitude, and 1086 new terms for the latitude. It 
was by having recourse to a new process of calculation, by which the work was 
broken up into parts, that M. Delaunay has been able to advance the calcu- 
lation of the lunar inequalities far beyond the limits previously reached. 
The Earl of Rosse has given to the Royal Society (in a paper read June 20, 
1861) some further account of researches in Sidereal Astronomy carried 
on with a Newtonian telescope of six-feet clear aperture. These researches 
are prefaced by an account of the process by which the six-feet specula were 
made, a description of the mounting of the instrument, and some considera- 
tions relative to the optical power it is capable of. A selection from the 
observations of nebulz is given in detail, illustrated by drawings, which con- 
vey an exact idea of the bizarrerie and astonishing variety of form exhibited 
by this class of cosmical bodies, 
Argelander, the eminent director of the Observatory at Bonn, is carrying 
on with great vigour the publication of his Atlas of the Stars of the Northern 
‘Heavens within 92° of Polar Distance. A large portion of this enormous 
work is completed, and two volumes, containing the data from observation 
for the construction of the Charts, were recently published. These volumes 
contain the approximate places of 216,000 stars situated between the parallels 
of 2° south declination and 41° north declination. 
Simultaneously with the construction of Star-charts, among which those 
of M. Chacornac of the Paris Observatory deserve particular mention, addi- 
tions have been made to the number of the remarkable group of small planets
