in each. For every one of these, the Eight Ascensions and Decli- 

 nations brought up to 1865 are given ; and besides these there are, as 

 often as possible, directions similar to the following for finding the 

 great nebula in the constellation AndrornedaB : " An imaginary line 

 drawn in the heavens from the star /J Andromedse, over the star fx, 

 Andromedre, and produced as far again beyond, will place the 

 nebida in the field of the telescope, with a low power eye-piece." 



We should have said that the catalogue has been specially pre- 

 pared with reference to the large maps of the Society for the Diffusion 

 of Useful Knowledge ; and that the possession of those maps is essen- 

 tially necessary to its use by the observer with a non-equatorial 

 telescope. 



The introduction contains valuable instruction in the use of in- 

 struments, catalogues of test objects, and a table of Refractions which 

 will be found very useful. 



PAMPHLET. 



Sericulture in Oudh.* 



Dr. Bona via has published, in the form of a pamphlet, printed at 

 Lucknow, during the year just closed, an account of the advance and 

 prospects of the acclimatization of the silkworm, and of the production 

 of silk in the province of Oudh, which, considering the short time that 

 the experiments have had to bear fruit, may be considered as en- 

 couraging. Silkworm experiments with China and Cashmere worms 

 have been conducted at Fyzabad, Seetapore, Baraitch, as well as 

 at Lucknow ; the latter under the superintendence of Dr. Bo- 

 navia. The China worms, however, became very sickly in the month 

 of October, which he attributes to the alternations of temperature — 

 the hot days and cold nights of that month. Nor could they be reared 

 during the cold months of November, December, and January. The 

 Cashmere worms did not yield very favourable results at first, the 

 cocoons being difficult of reeling, and the thread often becoming en- 

 tangled and continually breaking. Nevertheless, a report of the Agri- 

 horticultural Society of India states that the native reelers, after a 

 week's training, improved greatly, and the quality of the silk is de- 

 scribed as excellent, though rather uneven. Two other kinds of worm 

 have been experimented on, namely, first the Boro-Pooloo silkworm 

 of Bengal, which produced good cocoons, which reeled very well. 

 This, which is described as a very good sort of worm, produces 

 cocoons for the most j>art perfectly white, but many are yellow, 

 and some white with a greenish yellow tinge, and of it Dr. Bonavia 

 remarks, that if he were rearing silkworms for commercial pur- 

 poses in Oudh, he should certainly prefer, for the winter crop, the
