214 VEGETABLE PARASITES. 



springing from spots; J. P. Frank (1792), exanthemata scabra, 

 he confounded them with stomatitis; Hufeland (1792), critical 

 phenomenon; Fleisch (1808), vesicles, stomatitis vesicularis; 

 Jahn (1803), local disease, dots, fissures, vesicles; Gardin (1807), 

 critical exanthem of white tubercles, moreover identical at all 

 ages; Capuron (1821), translated by Puchelt, a critical exanthem ; 

 A. G. Richter, pustulous exanthem; Good (1822), granulated 

 vesicles; Wendt (1823), white spots and vesicles; Josephus

5th period. The period in which Muguet meets with a special 

 description, and is separated from aphthae, by the French school. 



Knellie, an Englishman, is the first who describes the Mugue.t, 

 although he does not give it that name. The French school 

 begins with the year 1738, when the attention of the government 

 was called to the excessive mortality at the Paris Hospital for 

 Children, with the work of Martinet, 1740, who calls the disease 

 Blanchet, or Muguet, and who ascribes to it a contagious cha- 

 racter, Colombier (1779), de petits boutons blancs et durs; 

 Doublet (1783) describes accurately the course of their develop- 

 ment. Amongst the competitors for the prize given at Paris, in 

 1786, who were successful, were Sarponts, who distinguishes 

 " aphthae in puncto albicantes et pustulae miliares," and recom- 

 mends inoculation as a protection ; Auvity, who separated aphthae 

 and muguet, and mentioned the glands of the mucous membrane 

 as their seat; Van de Vieupersse, who classifies them with the 

 exanthemata, as being more related to miliaria, and therefore 

 critical, and knew that the vesicles discharge no liquid; Coop- 

 mans, who says, the word aphthae was used for " stomacace " and 

 " noma J> by ancient writers, whilst they are tubercles or pus- 

 tules around the rectum aphthae are the same in the North 

 as miliaria are in the South; Arnemann, who says, aphthae are 

 neither ulcers nor pustules, but white tumours, consisting of three 

 species the commonest are those of foundling-hospitals, and 

 those of grown-up people, which latter alone are critical ; and 

 Lentin, who calls them a non-critical formation of papillae. 

 Wedekind knows them to exist in an isolated state (Stomatitis 

 follicutaris) , and aphthae in heaps (true aphthae and diphtheritis) ; 

 Hecker (1815), in his otherwise good description, is, however, 

 defective, he divides Aphthae neonatorum } the same as " soor" and 

 Schwammchen (thrush) ; Bertin (1810) ; Geoffrey (in the ' Dic- 

 tionnaire des Sciences medic,/ 1812) ; Dievilliers (1819, ibidem,
