Malta 1820 Fell ill with a violent orchitis which Lindsay said was "brought on by the unusual heat and climate of that island". In 1827, Lindsay wrote to the Secretary for War, The Most Honourable the Viscount Palmerston where he complained that after eight years he still suffered pain and inconvenience and hoped that his Lordship will grant him some remuneration".1 It is possible that his illness was Malta Fever or Brucellosis which like mumps also presents with an inflammation of the genitals.

Malta 4 Mar 1824 Promoted Surgeon 18th (The Royal Irish) Regiment of Foot. On 15 Mar 1824, the Director General Army Medical Services wrote to Lindsay about the Officers' Benevolent fund encouraging a donation to the fund. McGrigor wrote " I am indeed happy to congratulate you on your promotion having appeared in the Gazette on Saturday, I beg to send you last year's report on our Charitable Institutions, that for the orphans and for cases of distress among officers of the Medical Department".1
On his promotion "a faithful friend" gave him a few words of advice on the new regiment that he was taking medical charge of. He warned "... they are of very bad material and very troublesome as far as their hospital concerns go. The medical department has long been rotten on the 18th and you have very odd people to deal with. The hospital sergeant, who remains here, is apparently a very simple and ignorant fellow- but I believe him to be the reverse and I know that he acts as as spy upon all the actions and words of the medical officer. I therefore caution you to trust him in nothing. The apothecary, Mr Davies is a very poor creature. Not a word passes in your corps that is not reported to the chief. In short follow the precept of our Divine Master, be harmless as a dove, but it will, in a peculiar manner, be hove you to be wise as a serpent. Forbid in the most positive manner the admission of female visitors to your hospital".1
1825 On duty with 18th.
