238 List of New Patents. 



" The experiments were made by Robert Bingley, Esq., the 

 King's Assay Master of the Mint; and the calculations by 

 Dr. Kelly, who planned and conducted the general compari- 

 son, and in 1821 published the Results in the Universal Cam- 

 bist, under the sanction of His Majesty's Government. 



" The undertaking was originally patronized and recom- 

 mended by the Board of Trade. The standards were pro- 

 cured from abroad by circular letters issued by Viscount Castle- 

 reagh and Earl Bathurst, Secretaries of State for the Foreign 

 and Colonial Departments ; and the whole plan was essentially 

 promoted by Lord Maryborough, Master of the Mint." 



DEATH OF MR. BOWDICH, THE AFRICAN TRAVELLER. 



We lament to state the decease of this accomplished travel- 

 ler and naturalist, which took place on the 10th of January, 

 at St. Mary's River in Gambia, Africa, in consequence of his 

 over-exertions in making a survey of the river. A widow and 

 three orphans survive him, who are altogether unprovided for ; 

 and we take this opportunity of announcing that a work which 

 Mr. Bowdich completed prior to his death, entitled " Excur- 

 sions in Madeira and Porto Santo," will be published by sub- 

 scription for their benefit. A prospectus of it, we believe, will 

 shortly be issued. 



LECTURES. 



Mr. John Edward Gray's Course of Lectures on Natural 

 History and Materia Medica, will commence in the middle of 

 April ; they will be illustrated with numerous specimens, prac- 

 tical demonstrations and excursions, which he has found to 

 be the only plan by which the pupil can be quickly furthered.
