8. New Permission Rifle, ignited by a Spring instead of a Look. 
Lieutenant Colonel Miller is the author of this improvement, which is stated to 
combine the following advantages. 1, It produces tire more suddenly than the com- 
mon lock. 2, It is less liable to get out of order ; and 3. It may be constructed at 
half the expense of an ordinary rifle. A favourable report of its performance as tried 
at Woolwich is annexed.— Phil. Mag. and An. Phil. vol. Hi. p 277.

The Atlas of India, published by the East India Company 
This noble work, of itself a splendid monument of the munificence of the East 
India Company, is upon a scale of four miles to an inch, and taken from actual 
surveys, which when completed will form a map of India on one uniform plan. 
The project was first conceived by Colonel McKenzie, and a large portion of those 
parts already published were surveyed under his superintendence. The surveys on 
the northern part of the peninsula have for their basis the triangtdation of Colonel 
Lambton, who extended a set of principal and secondary triangles over the whole 
country. 
The sheets are published as they are completed ; some of them have blank 
spaces, to be filled up as the surveys proceed ; nothing being allowed to go forth 
to the world which is not founded upon actual survey. The following are the sheets 
already published. 
Sheet 17 contains the surveys of Captain Hodgson and Lieutenant Herbert in the 
mountainous country comprising the northern part of the province of Sirmur, and 
the principal part of Biss&hir. 
Sheet 48 contains the surveys of Captain Hodgson and Lieutenant Herbert in the 
Southern part of the province of Sirmfir, part of Garhwal, and the Delira Dfin. 
The flat country is from the surveys of Lieutenant White, Lieutenant Hodgson, 
Captain Colvin, and Lieutenant Blake. 
Sheet 65 is principally the survey of Captain Hodgson and Lieutenant Herbert 
of the sources of the Ganges, and of Captain Hearsey and Mr. Moorcroft of the 
sources of the Indus and Setluj. 
Sheet 66, is principally the survey of Captain Webb, of the province of KamAun. 
Sheets 69 and 70, contain the greater part of the province of Bandelkund sur- 
veyed by Captain Franklin, brother of Captain Sir John Franklin, R.N. 
Sheets42, 43,58,59, 60, 77,78,80,81,95, are surveys executed in the peninsula.

Survey of the Heavens. 
It will be recollected by our astronomical readers that in the plan published by 
the Berlin Academy in 1825, for the construction of a new map of the Heavens, it 
was proposed to survey a zone equal to thirty degrees in declination, namely 15“ 
above, and 15° below the equator ; and that this zone was to be divided into twenty- 
four hours of right ascension, each of which was to he assigned for the observation 
of one individual. Any astronomer wishing to be employed on the map, was to 
address himself to one of the members of the commission appointed for the object 
by the academy, who would assign for his portion any of the hours of the zone, not 
undertaken by another. This region was to he allotted to each observer for two 
years, and at the end of this time, if no real progress had been made, the commis- 
sion was to lie at liberty to appoint another observer. The whole was to be finished 
by January 1st 1829. We now read in some late numbers of the Antol.'gia, that 
two astronomers have furnished the task assigned to them, namely, M. Icghirami 
of Florence, and M. Harding of Gottingen The Italian astronomer bad undertaken 
the 18tli hour, one of the most difficult, as it contains the greater part of the milky 
way comprehended in the zone : his map contains a list of nearly 7500 stars, of which 
only 1500 were set down in the catalogues of Bradley, Fiazzi, Lalande, and Bessel ; 
the other 6000 are the result of his own observations- Notwithstanding the vast- 
ness of the undertaking, M. Inghirami has been the first to complete bis part of the 
map. These details are stated by M. Encke, Secretary to the commission, and are 
inserted in the Italian Journal. M. Harding, who was entrusted with the 15th 
hour, has only recorded 3000 stars. The results of the labours of the other astro- 
nomers are not yet known. — For. Qu. Rev. vol. iv. p. 332.
