in each part is too small ; but we flatter ourselves that a little 

 consideration will satisfy the intelligent Gentlemen to whom we 

 allude, that they are as numerous as is consistent with the size 

 of the part. The average number of papers in each, we find, 

 ejxceeds 20 ; so that in the first volume are contained more than 

 120 different papers, of which a very considerable proportion 

 are original. 



It has also been complained that too great a proportion of the 

 Annals has been devoted to Chemistry. We admit that, like 

 all other journals of the present day, our Annals must contain 

 a greater proportion of Chemistry, which is making a rapid 

 progress, than of those sciences which are in a great measure 

 stationary. But any person who will run over the contents of 

 our volume, will find essays belonging to the following branches 

 of knowledge, namely, Agriculture, Anatomy, Astronomy, 

 Biography, Botany, Geognosy, Hydraulics, Magnetism, Medi- 

 cine, Meteorology, Mineralogy, Optics, Physiology, Statistics. 

 This comprehends as many different sciences as could well have 

 been expected to make their appearance in one volume, and 

 more indeed than we anticipated in the outset. 



We expect every day to receive complete sets of the French 

 and German periodical works for the last three years ; which 

 will in all probability furnish us with interesting matter to fill 

 that department of our Annals which would otherwise lie vacant 

 during the summer recess of the Philosophical Societies of 

 London. 



One other topic it may, perhaps, be proper just to notice. 

 Several letters have been received mentioning the small number 

 of contributions that have been furnished to the Annals by the 

 different philosophers of Great Britain, and regretting the great 

 weight that has fallen, in consequence, on the Editor; but the 

 Editor himself is of a different opinion, and acknowledges with 

 pleasure that the number of contributions has greatly exceeded 

 his expectation. He had laid his account with conducting the 

 Annals of Philosophy for at least a year without any assistance 

 of much consequence ; but he has been agreeably disappointed. 

 He can already reckon among his contributors the names of 

 some of the first scientific men in Britain ; and he lies under 

 obligations of an equally important nature to other eminent 

 men, who have not permitted him to make their names public.
