362 CALENDAR, 1811. 



APRIL 5th. Tadpoles abundant : I made an experiment 

 to show that they would live and grow to maturity in distilled 

 water. I observed to day, for the first time, the Blackcap 

 Motacilla alricapilla at Waithamstow.

 thamstow.

 first heard the Cuckoo. 



MAY 13th. Papaver orientate has been in full flower at 

 Clapton for some days past. The Redstart has a nest with 

 eggs already in the garden.

 annually about this time, in the small border with a Southern

16th. Walking with my sister at Upper Clapton this 

 gvening I observed very curious cymoid forms of the Wane-

 bed of Sondercloud prevailed.

28th. Being at Eaton near Norwich, I noticed this evening 

 the whole welkin to be replete with beautiful Sonderclouds

 Crowmer. 



AUG. 10th. The night was clear after a showery day, re-
