* From Alcyonium, to which the name implies a rcsemljlance.

 tutes the base of the polype, is composed of a series of stout short setae. 



X Thorn. Johnson. " He was bom near Hull, in Yorkshire, bred an apothecary in 

 London, and afterwards lived and kept a shop on Snow-hill; where by his unwearied 

 pains, advanced with good natural parts, he attained to be the best herbalist of his 

 age in England." He was created M.B. in 1642, and on May 9th 1643 M. D. 

 Oxon. at which time he was " a Lieutenant-Col. in the garrison of Basing-House in 

 Hampshire, whence going with a party, on the 14th of September 1644, to succour 

 certain of the forces belonging to that house which went to the town of Basing to 

 fetch provisions thence, but beaten back by the enemy, (headed bj"^ that notorious 

 rebel, Col. Rich. Norton,) he received a shot in his shoulder, whereby contracting a 

 fever, he died in a fortnight after in the said house : at which time his worth did 

 justly challenge finieral tears, being then no less eminent in the garrison for his valour 

 and conduct as a soldier, than famous through the kingdom for his excellency as nn 

 herbalist and physician." Wood's Fast. Oxon. p. 39.
