In the nomenclature adopted in the preceding Catalogue it has been 

 my wish strictly to adhere to the Rules proposed by the Committee of 

 the British Association for the Advancement of Science, published in

I have to acknowledge my sense of obligation to the Ilon'ble Sii 

 William Norris, late Recorder of II. M. Court of Judicature in the 

 Straits of Malacca, to W. T. Lewis, Esq. Asst. Res. Councillor, Prince 

 of Wales Island, to W. Montgomerie, Esq., M. D. late Senior Surgeon^ 

 Straits of Malacca, and to Capt. Congalton, H. C. Steamer Hooghly 

 for their assistance, to me so much more acceptable, as the limited 

 leisure left me by the superintendence of six Hospitals in Prince of 

 Wales Island, and a seventh in Province Welleslcy, was latterly curtailed, 

 by additional, extra-professional duties, imposed upon me by the present 

 local head authority in the Straits.
