In 1824 the Caledonian Mercury under the heading of Naval Promotions and Appointments -  Alexander Neill, formerly a Surgeons' Mate, had been promoted to Assistant Surgeon (59).

Four years later he was serving as assistant surgeon on the Sybille off the coast of Africa -

 "On Thursday the Esk, Captain Purchas arrived in Portsmouth from the coast of Africa. The Esk left Sierra Leone on 5th January in company with the Sybille and the Black Joke. In running down the Coast, they captured a Spanish slave vessel with 175 negros.  The merchant seamen at Sierra Leone had suffered much from sickness arising principally from the indiscretion of the Master actively employing their crew, without the precaution of providing awnings to the boats in the heat of the day. The Surry of London had sent sixteen men to the Hospital set up at Sierra Leone, then under the charge of Mr. Alexander Neill, Assistant Surgeon of the Sybille, and on investigating the cause of their illness, Mr. Neill learnt that they had in a short space of time discharged a large cargo; that they had proceeded up the River to take in timber many exposed in the upper part of their bodies to the sun while the lower parts was immersed in water, whilst others were in the hold stowing away the timber, exposed to the damp and miasma. Mr. Neill was successful in his mode of treatment, and had been generally so, having on a former occasion restored to health, seven out of eight of another vessel's crew.. The North Star and the Primrose were cruising in the Bight of Benin."  - Hampshire Telegraph, 3rd May 1828 -
