Thomas Stewart Traill, M.D. of Liverpool, and Joseph Walker, Esq. of Allerton. For some beautiful specimens 
bted to the accomplished pencil of 
of drawings from living plants in the Botanic Garden at Liverpool, I am inde 
Miss Rebecca Miller, who in this department of the art has not often been rivalled. 
Jaw Mrs. Edward Roscoe, and in various degrees by 
Fletcher and Miss Mary Waln. It is with great 
acknowledgments to the Committee and 
And obligations of a similar 
kind have also been conferred upon me by my daughter-in 
her sister Mrs. James Dixon, by Miss Ellen Yates, Miss Emily 
pleasure I avail myself also of the present occasion to return my 
Proprietors of the Botanic Garden at Liverpool, for the accommodation which I have received at all times from 
their Institution. Nor must I omit to return my sincere thanks to Mr. John Shepherd, now for nearly 
thirty years the assiduous and skilful curator of that garden, and to Mr. Henry Shepherd, F.L.S. for 
their continual assistance and unremitting attention to me in my labours, which have rendered them a pleasure 
to myself, and will, I hope, entitle them to the favourable estimation of my friends. Lastly, I have to 
notice Mr. Thomas Allport, a meritorious young Artist, who by his commendable diligence has obtained a 
considerable degree of excellence in Botanical delineations, and finished from the living plants a great portion 
of the drawings for the following work, all of which have been engraved and coloured under the care 
and direction of Mr. George Graves, Jun. of Peckham.
