April 4. — N.E. Cloudy morning, afterwards fair and 

 calm, with various clouds. 



April b. — Wind very calm and variable ; curmdostratus 

 prevailed through the day; in the afternoon gentle nimbi; 

 a sort of conButnt rirroai7727</t/5 disposed in rows appeared, 

 in the fair intervals, above the artmilosfrnti, which pro- 

 duced rain by inosculation. Birds sing, and gnats and flies 

 appear. 



April 6. — Chiefly cloudy and hazy. 



April 7. — S. — S.E. — E. Cloudy, followed by rain, but it 

 held up a-jain at night. 



/ipril 8. — E. Some rain early; when it cleared, several ill- 

 defined modifications as usual. Clear and very cold nit^ht. 

 April g. — E. Clear morning ; it afterwards became 

 clouded with cinmilostratus, and other defined clouds; 

 none of the modifications have lately been well marked.

 form haze threatened rain, which however, did not come 

 down ; wind gentle and varioMS. 



April 12. — E. — W. Cloudy morning, and fair afternoon, 

 with light fleecy masses o^ cumulus apparently diiriinishing 

 by evaporation, and nearly stationary : lower down fibrous 

 cirri passed alontj in a oeulle gale from the west. This is 

 an inversion in the general order of clouils worth notice j 

 in the evening features of cirrosiratus. 



April 13. — Cloudy morning, fair afternoon; clear and 

 eold easterly wind ; cumulus and cumulostrntiis. 



April 14. — Cold easterly wind, rather lofty masses of 

 cumvbis through the day ; in the evening cirri passed ov.er 

 from the west, some of them opposite to the setting sun 

 showed a fine red colour : cirrosiratus also observed ; very 

 clear cold night. 



April 15. — S.E. This morning a veil of cirrtis taking 

 on here and there the cirrocunmlative form, while cumuli 

 of various degrees of density and various fi<j;ures rolled un- 

 der. The fall of the barometer and irregular strength of the 

 wind indicated a change of weather ; but the; day continued 

 fair, and the night particularly clear. The blueness of the 

 sky, however, was not so great this afternoon as in the 

 morning. 



April 16 — S.E. Early, a confused veil of cirrus appeared 

 spread aloft, while cumuli sailed under, and produced cu- 

 muloslratusy which ohsciued the skv. In the course of the 

 day nimbi formed in diflcrent places, and a few drops of 



rain
