BRITISH ZOOPHYTES. O 



to Martin Folkes, the Presideut of the Royal Society, 

 in which he entered into descriptions of his own 

 experiments confirmatory of those of Trembley. 



Baker also discovered Lophopiis Grystallinus in 

 Enerland. He named it the " Bell-flower animal.'* 

 Leeuwenhoek had discovered the Hydra in 1703; but 

 its remarkable properties were not found out until 

 the experiments of Trembley. These experiments 

 were communicated by him to Reaumur, who stated in 

 the preface to the sixth volume of his " Memoires pour 

 servir a FHistoire des Insectes/' that he had repeated 

 the most important of Trembley^s experiments, and 

 to his great amazement found every one to exactly 

 answer the accounts given. These curious investiga- 

 tions seem to have attracted the attention of meta- 

 physicians as well as naturalists, for in 1752, Dr. 

 Parsons, F.R.S., found it necessary to publish some 

 " philosophical observations, in which he answered 

 some objections against the indivisibility of the soul, 

 which had been inadvertently drawn from the late 

 curious and useful experiments upon the Polypus and 

 other animals ;" which observations, that they might 



prey. With an account of their diseases and cures ; of their 

 amazing Repeoduction after being cut in pieces (as first discovered 

 by Me. Teemblet at the Hague ;) of the best methods to 

 perform that operation, and of the time requisite to perfect the 

 several parts after being divided : and also full directions how to 

 feed, clean, manage and preserve them in all seasons of the year> 

 likewise a Course of real Experiments performed by cutting 

 these creatures in every way that can be easily contrived : showing 

 the daily progress of each part towards becoming a perfect 

 Polype. The whole explained everywhere by great numbers of 

 proper figures, and intermixt throughout with a variety of Obsee- 

 VATiONS and Expeeiments by Henry Baker, F.R.S." 1743.
