respecting the egg, in which he followed out the 

 views of Fabricius. In the troubles which suc- 

 ceeded the death of the unfortunate Charles, the 

 house of Harvey was pillaged; and he lost the whole 

 of the labours he had bestowed on the generation 

 of insects. His wor, Exercitationes de Genera- 

 tione Animalium, was published at London in 1651 ; 

 it is more detailed and perfect than that of Fabri- 

 cius; but the author was prevented by the un- 

 settled condition of the country from getting figures 

 engraved to accompany his descriptions. 



Many succeeding anatomists pursued the exami- 

 nation of the series of changes in generation, and of 

 the organs which are concerned in them, especially 

 Malpighi, who employed the microscope in this 

 investigation, and whose work on the Chick was 

 published in 1673. It is impossible to give here 

 any general view of the result of these laborious 

 series of researches : but we may observe, that they 

 led to an extremely minute and exact survey of all 

 the parts of the foetus, its envelopes and appen- 

 dages, and, of course, to a designation of these by 

 appropriate names. These names afterwards served 

 to mark the attempts which were made to carry the 

 analogy of animal generation into the vegetable 

 kingdom. 



There is one generalization of Harvey which 

 deserves notice 5 . He was led by his researches to 

 the conclusion, that all living things may be pro-
