Andrew Crosse was a country squire in the Quantocks, where he lived all his life on his estate, and spent all his leisure 

 for fifty years in electrical research, a pursuit in which he has had few fellows save the late Lord Salisbury. In 1837, while 

 experimenting on electro-crystallisation, he made the remarkable discovery of the appearance of insect life in immediate 

 connexion with his voltaic arrangements, and in metallic solutions supposed to be destructive to organic life. The insect 

 was named acarus electricus. On publishing a discovery so suggestive of abiogenesis he was, in his own words, ' met with 

 so much virulence and abuse that it seems as if it were a crime to have made the experiments ' (D. N. B.). The author of 

 the above Memorials, ' a charming volume, full of graceful and vivacious reminiscences ', was his second wife, and survived 

 him for forty years, during which she knew Murchison, Faraday, Babbage, Landor, the Brownings, Kinglake, and many 

 others, of whom she recorded her remembrances in ' Red Letter Days of my Life ' in 1892.

'He constructed most delicate telescopes, and made important modifications and simplifications of electrical methods. 

 He was the first to show, that when the temperature of one junction of certain thermo-electric circuits was gradually 

 raised, the current gradually rose to a maximum, then fell off, and finally was reversed at a red heat.' G. T. Bettany. 



' Gumming appears to have been the first to use a coil surrounding a pivoted needle to measure the current. To him we 

 owe the term (Galvanometer.' Prof. Silvaniis Thompson.

By way of variety from the then prevailing phlogistic theory, the anonymous author originates a still more peculiar theory 

 of his own, as stated in the introduction: ' Tho ingenious author has herein laid a great many Experiments and Observa- 

 tions together, in order to prove that Water is the only first Material Principle of Natural Bodies ; and that all the other 

 pretended Hypostatical Principles are ultimate and reducible into mere Elementary Water '.
