Dear Father

I have got a cold & unless it sets much better tomorrow I shant go to Kew.² I wrote to D^r H³ to tell him I shouldnt come most likely & said about the price of the Micro’s & that Hartnack didnt mention any agent— Our micro’s are both petit nouveau modèle. I cant say about the “grande ouverture” no mention of that was made in ordering them I think. My micrometer is N^o 2 Eyepiece 3—Object Glasses 4; 5; 8. I will find out about the micrometer values the ones which are badly written. I will ask him which is the best immersion & learn how to use it.⁴ I told Hooker that Klein says Tisley & Spiller’s micros are absolutely the same as the ones he keeps in Paris—⁵
