[Louisiana] Jan. 17. Another very cold night, about like our Maine weather the middle or last of November. Last Monday night was very warm, & we had a warm rain Thursday; but the change since then has been greater than we often have at home at any season. This morning the ground was frozen considerably in low spots, & ice formed a quarter of an inch thick on small puddles of water. It is not strange that men get colds & coughs at such times. Had a Reg. inspection of arms & clothing this P.M. by the Lieut. Co.. & Major. I have made out a “certificate of disability” for Franklin Holbrook today, but there is some doubt about his getting a discharge, though I think he is very anxious to have one. He has been in Hosp. all the time we have been here. I have had a dry hacking cough for some days, though it is not very troublesome. Otherwise I feel very well.
